gPXE: remove the gPXE contrib directory

Remove the gPXE contrib directory.  We don't use it, and it causes
trouble with rpmbuild due to .spec files.

-This utility was apparently writen by John Finlay and came to me
-via Richard Schroeder who got it from Greg Beeley. John, if you want
-to be credited with your full address or whatever in the Etherboot
-documentation, please contact me (Etherboot maintainer).
-
-1/18/2000 Marty Connor (mdc@thinguin.org) added code for the 3C905C
-with AT49BV512 Flash memory, and created cromutil and bromutil to
-differentiate the versions.  cromutil is for 3C905C and bromutil is
-for 3C905B.
-
-Be careful. You can easily erase your Flash memory using these
-utilities.  Make *sure* to back them up first using the "read"
-command. You must "erase" before using "prog" to program the chip with
-Etherboot code.  This code comes with NO WARRANTY, and you take sole
-responsibility and liability for whatever it does.  Read the
-"romutil.txt" file for more information on commands.
-
-That being said, if you are programming a 3C905C-TXM (for example)
-you would do something like this:
-
-    $ cd etherboot-x.x.x/contrib
-    $ tar -zxvf n3c905xutil.tar.gz
-    $ cd n3c905xutil
-    $ make
-    # replace 0x6600 with whatever the IO Addr for your card is!!!!
-    $ ./cromutil 0x6600 read > 905cbackup.bin
-    $ ./cromutil 0x6600 erase
-    $ ./cromutil 0x6600 prog < 3c90x.lzrom
-
-You should now have an Etherboot-enabled 3c905C-TXM.

-I wrote the attached little util program to try out the basic approach
-and thought that you might find it useful as well as providing some
-simple testing. It isn't a final solution so the interface is rough. The
-program must be run as root on an Intel based machine.
-
-The key point is that the IO address needs to be entered - I grab it
-from the dmesg output:
-
-eth0: 3Com 3c905B Cyclone 100baseTx at 0xe400,  00:10:4b:d2:5e:0d, IRQ
-11
-
-or "cat /proc/pci" to find the "I/O at XXXXXX" for your 3Com Card.
-
-Some example commands are:
-
-romutil 0xe400 erase            - erases the ROM contents
-romutil 0xe400 protect            - enables the Software Data Protection
-on the ROM [3c905B only]
-romutil 0xe400 unprotect       - disables the Software Data Protection
-on the ROM [3c905B only]
-romutil 0xe400 id                    - displays the manufacturer and
-device IDs
-romutil 0xe400 read >file    - writes the contents of the ROM to stdout
-romutil 0xe400 prog <file    - writes the contents of the stdin into the
-ROM (<64k)
-
-I tried reading and writing the ROM while doing large ftp transfers and
-experienced no problems. I didn't spend much time worrying about the
-possible race conditions. My system has lots of resources (450MHx P2,
-128MB RAM) so it might not provide the best test candidate.
-
-Let me know what results you get if you try it out.
-
-Thanks

-1. Introduction.
-
-
-1.1. What is it for?
-
-This document describes how to build software distribution to run Java client on diskless 
-terminal booted from Microsoft Windows 95/98/NT workstation. Package can also be easily 
-modified to be used as Linux terminal or X Windows terminal's software. I found it also 
-convenient for setup over the Ethernet of floppyless PS's, hard disk of which for some 
-reason can not be accessed (sealed case under warranty, etc.).
-
-
-1.2. Do we need this HOWTO?
-
-To be honest, I'm not sure. There are few excellent HOWTO's (see 3. Recources) that up until 
-recently I considered quite sufficient to build what I've done two years ago. But since my 
-project uses MS Windows as a file server vs. traditional NFS there were some know-how's 
-involved which number of people wanted to see in some formal document.
-
-
-1.3. A bit of history.
-
-My project at that time (1996) was to find OS/JVM that will allow to run Java application 
-on hardware we manufacture. Hardware is practically generic x86 PC except it has no keyboard, 
-hard drive, floppy drive, mouse, but touchscreen over LCD, plus some POS specific peripherals 
-(badge reader, credit card reader, etc.). Due to cost consideration it had no any significant 
-storage, so OS and Java client along with support binaries, libraries etc. had to be loaded 
-remotely. Because our clients are exclusively Windows shops, Server had to be Windows as well. 
-During evaluation of different commercial OS'es along with JVM's available it become apparent 
-to my surprise that most promising solution was GPL one - Linux.
-
-
-2. Project description.
-
-2.1. Packaging.
-
-The whole distribution consists of remote file system (RemoteFS) residing on MS Windows
-server (NT Workstation, NT Server or Windows9x) and tagged bootable image. 
-
-
-2.2. Image.
-
-Image (~1.5MB) is generated by mknbi utility that comes with Etherboot package
-<http://etherboot.sourceforge.net>. It can include minimal root file system (MRFS) 
-like in my case (since I had to boot client from MS Windows server and Linux kernel doesn't 
-support SMBFS-Root, only NFS-Root. So I had to keep rootfs in the ramdisk). To generate 
-image the following script can be used.
-
-#!/bin/sh
-# mkrootnet: makes tagged netbootable image
-# This image includes kernel and minimal root filesystem
-# to do initial boot.

-echo "Uploading $BOOTIMAGE to $UPLOAD"
-cp $BOOTIMAGE $UPLOAD
-echo "Cleaning after ourselves"
-rm -f $KERNELTMP $DEVICEFILENAME $BOOTIMAGE
-echo "All done"
-
-
-In the above script actual image is generated by the following comand
-
-#mknbi -d ram -i rom -r rootfs.gz -k vmlinuz-nt -o img
-
-where:
-	rootfs.gz - minimal root file system (MRFS);
-	vmlinuz-nt   - kernel;
-	img       - resulting image.
-
-
-Note:
-Default ramdisk size is 4096. It was enough for RedHat4.1 based minimal file system, but 
-apparently not enough for 5.2 based. When this happens "end request:I/O error, dev 01:00 ..." 
-error shows up. To fix that either use "mknbi -a ramdisk_size=8192" to pass parameter to the 
-kernel (doesn't require kernel recompilation), or change /usr/src/linux/drivers/block/rd.c: 
-int rd_size= from 4096 to 8192 or whatever and rebuild the kernel.                                                    
-
-
-2.2.1. Kernel.
-
-Kernels 2.0.30 and 2.0.36 have been used by author, although nothing is preventing you from
-experimenting with others. Kernel should include ramdisk support. The following 
-<link to .config> configuration has been used to build <link to binary (kernel 2.0.30)>. 
-You may find some components unnecessary, just exclude them and rebuild. 
-
-Don't forget to change root device after you built the kernel (rdev vmlinuz /dev/rd).
-
-Gotcha's: apparently smbfs is broken in 2.2.x kernels. Symptoms: remote share is mounted
-just fine but after a while fails with "smb_request: result = -32" errmsg. I've heard
-SuSe has fix for that.
-
-2.2.2. MRFS.
-
-Minimal root file system is required to get Linux up and running along with networking until 
-it can mount remote file system to run X/Java from there. After image gets loaded from the 
-server MRFS is decompressed into ramdisk. If you can afford a lot of ram on your terminal the 
-entire remote file system can be moved to rootfs.gz. That will make your terminal more 
-responsive.
-
-
-2.2.3. Building MRFS.  
-
-Some folks found it easier to start from scratch, others use known "minimal" Linux distributions
-(Linux Router, tomsrtbt, etc.), yet others prefer to start from "big" Linuces like I did. Every
-path has it's pro and contras.
-
-Pruning standard distribution (RedHat, Debian, etc.) to your needs might be very time consuming.
-To ease that painful process I have used remotely booted diskless client with NFS-Root (see 
-Etherboot's Readme, NFS-Root and NFS-Root-Client mini-HOWTO's, Diskless-HOWTO):
-
-- setup minimal RedHat4.1 install (networked workstation, X, no development, mail, etc., ~117MB);
-- find . -print|cpio -pmd /usr/NFS/ROOTFS - copy entire fs tree to NFS exported dir;
-- mknod /usr/NFS/ROOTFS/dev/nfsroot b 0 255;
-- build vmlinuz-nfs kernel according to NFS-Howto (built-in bootp,rarp,NFS,NFS root,NIC 
-  driver,RAM disk);
-- rdev vmlinuz-nfs /dev/nfsroot - to set NFS root device; 
-- build image for NFS-Root fs:
-  #mknbi -d rom -i rom -k vmlinuz-nfs -o nfsImage;
-- boot client while monitoring NFS file requests (by Solaris snoop);
-- copy files from /usr/NFS/ROOTFS to /usr/BOOT/ROOTFS (MRFS model) according to snoop's
-  filelist;
-- generate image by mkrootnet script (don't forget to point to the right kernel vmlinuz-nt).
-
-The above trick not only allows to determine the sought files set but also debug boot process 
-analyzing NFS messages. I found it convenient to put "read tmp" statements into init scripts
-for debugging. Tracking files up until issuing login gives you <link to rootfs.gz> MRFS (~1MB) 
-that can be used to boot Linux from ROM (flash, eprom, DiskOnChip, SanDisk, etc.) as well. All 
-the other files requested by client (during starting X, Java, Java client) were put into (link 
-to remotefs.zip, ~9MB).
-
-
-To restore MRFS model on your PC from the above rootfs.gz:
-- #cd /tmp
-- #gunzip rootfs.gz
-- #mount -o loop -t ext2 /tmp/rootfs /mnt
-- #cd /mnt
-- #find . -print|cpio -pmd /usr/BOOT/ROOTFS
-- #umount /mnt
-
-Note: 
-
-You will have to change attributes of some dirs, files (/etc/mtab, /etc/mtab~, /var/lock/subsys/*, 
-/var/run/*, /dev/tty*, etc.) against standard. This is because with standard attribs diskless 
-client refused to work. For example I had to change /dev/tty* ownerships to 99:99 from original 
-0:0 or 0:5, to get rid of errmsg "INIT: Id "1" respawning too fast: disabled for 5 minutes". 
-Being admin illiterate I just chmod them to 777 and chown to 99:99 to make life easier. 
-THIS IS SERIOUS SECURITY VIOLATION!!! Using keyboardless terminal with no daemons running in 
-my case reduces the risk, yet I would appreciate very much those more experienced who will help 
-to restore the right attribs while keeping the distribution working.
-
-Some "gotcha's" to watch for during MRFS building:
-- standard attributes/ownership of some files don't work;
-- rdev must be set (non-tagged image didn't work, so couldn't use config file to pass parrs 
-  to the kernel);
-- diskless client writes 99:99 ownership on generated files;
-- "password incorrect" for root, but any other OK and su OK too.
-
-
-2.3. RemoteFS.
-
-Remotefs.zip file includes everything required by the system that can be located on
-remote file system, i.e after booting has been complete and remote file system mounted.
-In my case it is X Windows System and Java binaries, libraries etc. To use that file on
-MS Windows NT:
-- unzip remotefs.zip to some directory;
-- share this directory read-only as "usr" (or share as some other name and pass this name to
-  the client through bootptab configuration file for BOOTP server;
-- create an account username=root, password=linux on NT (can be set in bootptab).
-
-Note:
-There's no symbolic links on NTFS, so UNIX links must be replaced by copies on NTFS. 
-To determine potential troublmakers one could use the following:
-- first copy required subset (according to snoop's intercept) from /usr/NFS/ROOTFS to 
-  /usr/BOOT/REMOTEFS;
-- mount some share from NTFS to /mnt;
-- /usr/BOOT/REMOTEFS#find . -print|cpio -pmd /mnt 2>links;
-In the links file you will find names to work with.
-
-
-2.4. Booting sequence.
-
-Boot occurs in the following sequence:
-- bootprom sends bootp request,
-- bootp server responds with subnet mask, client's name, client's IP, TFTP server's IP, 
-  bootfile name and some optional parameters (like NT's username/password to use it's share,
-  you could pass some other share name here as say T104="somedir");
-- bootprom downloads image from TFTP server;
-- kernel starts;
-- kernel decompresses MRFS in RAM;
-- system starts init using ramdisk root,
-- mounts remote file system from NT via SMBFS;
-- automatically logins;
-- starts xstart script located on remotefs (/usr/sbin) where you can start any of your
-  programs, change parameters, etc. without rebuilding the image.

-Gotcha's:
-Looks like smbmount client from smbfs package used to mount remote Windows shares to local 
-Linux dirs in pre 2.2.x era isn't maintained anymore so you should use one coming with 
-Samba package. Also binary smbmount won't work with 2.2.x, so you have to recompile with 
-2.2.x headers following Samba's readme. Yet even that won't guarantee reliable work until
-somebody fixes kernel's smbfs module.
-
-2.4.1. BOOTP, TFTP.
-
-There are number of BOOTP, TFTP servers for Windows on the market. You could find them
-here:
-
-- www.walusoft.co.uk (Walusoft's tftp);
-- ftp.coast.net/simtel/nt/internet/tftpds12.zip (Millwood AB's tftp);
-- ftp.cabletron.com/pub/snmp/bootftp/boottft2.zip (Cabletron's bootp/tftp combo);
-- www.tellurian.au.com (Tellurian's bootp, tftp, dhcp servers).
-- www.metainfo.com (Metainfo's DHCP server)
-- www.nts.com (Network Telesystems's DHCP server in IPserver package)
-
-My choice was Tellurian's products - very reliable, simple to install, attractively priced
-(fully capable evaluation versions are available).
-
-2.5. Bootprom.
-
-Ken Yap's Etherboot <etherboot.sourceforge.net> will tell you everything about bootprom. 
-Here I just want to mention that normally you would have to put bootprom's code into network
-adapter's PROM. But if your hardware like mine has BIOS programmed in flash you could 
-re-program it to add bootprom (some BIOS requires special programmer to do that, others don't)
-as BIOS extension.
-
-This is what I did to add ne.rom (bootprom generated by Etherboot's makerom for NE2000 clone) 
-to AMI BIOS on my flash:
-
-- read flash content by programmer into bios.bin binary file;
-- use one of available binary editors (say www.simtel.net/Win95/editors/hxp3005.zip to add
-  ne.rom to bios.bin (and to edit ne.rom if necessary);
-- write new bios.bin back to flash.
-
-Notes:
-- makerom generates bootprom for standard EPROM sizes (8k, 16k, 32k, etc.), so if you tight on 
-  space use -s flag to adjust size (or cut it manually to multiple of 512 bytes blocks, just
-  don't forget to adjust extension's length which is coded in Byte 2 and checksum to 8 bits 
-  of zero;
-- valid absolute addresses for BIOS extensions are from 0xC8000 to 0xF4000 (check with 
-  motherboard's manufacturer how flash is mapped onto system memory space);
-- Byte 0 must be 0x55, Byte 1 must be 0xAA, Byte 2 must be extension's length in 512 bytes 
-  blocks;
-- extension BIOS has to start at a 2k boundary;
-

-Date:        11/9/2001 3:56 PM

-From:        Steve Tilden, stilden@sicom-sys.com

-2)  I have added conditional code to main.c from Etherboot 5.0.4 to add
-a new default boot option and I have included the modified main.c as an
-attachment to this message.
-
-As I received Etherboot 5.0.4, in the Config file, if you select
-ASK_BOOT with a non zero time-out option, then you also get to set
-ANS_DEFAULT = ANS_NETWORK or ANS_DEFAULT = ANS_LOCAL to determine what
-will happen if the operator does not respond to the prompt.   I have now
-added conditional code in main.c such that if you set ANS_DEFAULT =
-ANS_AUTO, the default answer will be set according to whether or not
-there is a hard disk in the system (as detected by the BIOS).  If a hard
-disk is present, then if the operator does nothing, the system will boot
-from it.  If a hard disk does not exist, then again if the operator does
-nothing, the system will boot via the network.  Either way, for our
-particular environment, the operator has to do nothing to get it to boot
-correctly.  Yet the operator can still override the default selection
-to, for example, allow a unit without a hard disk, to boot directly from
-a floppy rather than the network, or to allow a unit with a hard disk,
-to boot from the network.
-
-I don't know it the code I have added might be correct for a future
-production version of Etherboot, but I thought I'd send it to you and
-let you get it into the system if you feel it might be appropriate.
-
-Thanks,
-

-[Ed: On a compliant BIOS, it will actually boot the next device in the
-BIOS list if local is selected, either explicitly or by timeout, which
-may or may not be the hard disk, which is why it's less than general and
-not included in the distribution by default.]

-# Makefile for Etherboot
-#
-# Most of the time you should edit Config
-#
-# Common options:
-#	VERSION=v	- Set the version string
-#
-# NS8390 options:
-#	-DINCLUDE_NE	- Include NE1000/NE2000 support
-#	-DNE_SCAN=list	- Probe for NE base address using list of
-#			  comma separated hex addresses
-#	-DINCLUDE_3C503 - Include 3c503 support
-#	  -DT503_SHMEM	- Use 3c503 shared memory mode (off by default)
-#	-DINCLUDE_WD	- Include Western Digital/SMC support
-#	-DWD_DEFAULT_MEM- Default memory location for WD/SMC cards
-#	-DCOMPEX_RL2000_FIX
-#
-#	If you have a Compex RL2000 PCI 32-bit (11F6:1401),
-#	and the bootrom hangs in "Probing...[NE*000/PCI]",
-#	try enabling this fix... it worked for me :).
-#	In the first packet write somehow it somehow doesn't
-#	get back the expected data so it is stuck in a loop.
-#	I didn't bother to investigate what or why because it works
-#	when I interrupt the loop if it takes more then COMPEX_RL2000_TRIES.
-#	The code will notify if it does a abort.
-#	SomniOne - somnione@gmx.net
-#
-# 3C509 option:
-#	-DINCLUDE_3C509	- Include 3c509 support
-#
-# 3C90X options:
-#	-DINCLUDE_3C90X	- Include 3c90x support
-#	-DCFG_3C90X_PRESERVE_XCVR - Reset the transceiver type to the value it
-#			  had initially just before the loaded code is started.
-#	-DCFG_3C90X_XCVR - Hardcode the tranceiver type Etherboot uses.
-#	-DCFG_3C90X_BOOTROM_FIX - If you have a 3c905B with buggy ROM
-#			  interface, setting this option might "fix" it.  Use
-#			  with caution and read the docs in 3c90x.txt!
-#
-#	See the documentation file 3c90x.txt for more details.
-#
-# CS89X0 (optional) options:
-#	-DINCLUDE_CS89X0- Include CS89x0 support
-#	-DCS_SCAN=list	- Probe for CS89x0 base address using list of
-#			  comma separated hex addresses; increasing the
-#			  address by one (0x300 -> 0x301) will force a
-#			  more aggressive probing algorithm. This might
-#			  be neccessary after a soft-reset of the NIC.
-#
-# LANCE options:
-#	-DINCLUDE_NE2100- Include NE2100 support
-#	-DINCLUDE_NI6510- Include NI6510 support

-Date: Tue, 10 Apr 2001 23:19:19 +0200
-Organization: Prisma Engineering srl
-
-Hi Ken,
-I have ported Etherboot on an embedded, biosless platform and would like
-to contribute the code.
-
-Essentially, the hardware I was running Etherboot is a Pentium based
-embedded system, with an Intel Chipset, *but* without serial, VGA,
-keyboard etc., only an 82559 Intel (custom) Ethernet controller (I debug
-it with the etheral Ethernet packet analyser and an emulator).
-
-What I did was:
-
-  a.. integrate the init.s file within the firmware, with GDT
-(re)initialisation (a simple and single entry point taking control of
-the boot process)
-  b.. provide some stupid BIOS stubs in order to let the OS boot and
-still belive that an INT10 call goes to the BIOS
-  c.. provide some basic functions to Etherboot, like timer (I used the
-Pentium TSC internal counter)
-  d.. hardwire in the code information about the RAM size
-The BIOS stubs are enough to boot Linux, pSOS and QNX with bootp. QNX is
-somewhat difficult to load, because the i82559 driver tries to find the
-component using the BIOS32 calls, so I had to patch it.
-
-what i I got from the original firmware is the PCI initialisation and
-resource (I/O, interrupts, memory) allocation.
-
-I send you what I changed, that is, the initialisation code and the
-misc.c file containing the timer, and the makefile (I don't remember
-exactly the options I used to compile all).
-
-Of course, it is only a good starting point for anyone wanting to
-implement a bootp client on a biosless platform; some integration work
-still needs to be done.
-
-Ciao
-Paolo
-
-And in a subsequent email:
-
-I worked with version 4.6.12, but the real modifications involve the
-init.S file, which I think is quite sstable between releases.  I forgot
-to say that my entry point (symbol _start in init.s) assumes the
-processor is already in protected mode.
-
-[The only difference between main.c and misc.c from those in Etherboot
-4.6.12 seems to be the deletion of eth_reset(). This may be of use to
-others trying to make these changes work on more recent releases. Ken]

-/* Intel Hex format specifications
-
-The 8-bit Intel Hex File Format is a printable ASCII format consisting of one
- or more data records followed by an end of file record. Each
-record consists of one line of information. Data records may appear in any
- order. Address and data values are represented as 2 or 4 hexadecimal
-digit values. 
-
-Record Format 
-:LLAAAARRDDDD......DDDDCC 
-
-
-LL
-AAAA
-RR
-DD
-CC
-Length field. Number of data bytes.
-Address field. Address of first byte.
-Record type field. 00 for data and 01 for end of record.
-Data field.
-Checksum field. One's complement of length, address, record type and data
- fields modulo 256. 
-CC = LL + AAAA + RR + all DD = 0
-
-Example: 
-:06010000010203040506E4 
-:00000001FF 
-
-The first line in the above example Intel Hex file is a data record addressed
- at location 100H with data values 1 to 6. The second line is the end
-of file record, so that the LL field is 0

-Running Etherboot within Bochs
-==============================
-
-Michael Brown <mbrown@fensystems.co.uk>
-Based on an idea suggested by H. Peter Anvin <hpa@zytor.com>.
-
-$Id$
-
-Bochs is a program that simulates a complete Intel x86 computer,
-including hardware.  It can be used to test Etherboot.  There is a
-special pseudo NIC ("pnic") implemented in Bochs, with a corresponding
-driver in Etherboot.  (There is also an NE2000 ISA driver in Bochs,
-but it doesn't seem to quite work.)
-
-To get bochs running is fairly simple:
-
-1.  Build the utilities in this directory:
-      make
-
-2.  Get the bochs source code:
-      cvs -d:pserver:anonymous@bochs.cvs.sourceforge.net:/cvsroot/bochs \
-           login
-      cvs -d:pserver:anonymous@bochs.cvs.sourceforge.net:/cvsroot/bochs \
-           co bochs
-
-3.  Configure bochs with
-      pushd bochs
-      ./configure --enable-all-optimisations --enable-show-ips \
-		  --enable-cpu-level=6 \
-		  --enable-pci --enable-pnic --enable-ne2000 \
-                  --enable-debugger --enable-disasm
-      popd
-
-4.  Build bochs:
-      make -C bochs
-
-5.  As root, set up a TAP virtual network device:
-      /sbin/modprobe tun
-      chmod o+rw /dev/net/tun
-      ./tunctl -u <username> -t tap0
-      /sbin/ifconfig tap0 up 10.254.254.2 netmask 255.255.255.0
-
-6.  As root, add the following fragment to /etc/dhcpd.conf:
-      subnet 10.254.254.0 netmask 255.255.255.252 {
-        range dynamic-bootp 10.254.254.1 10.254.254.1;
-      }
-    You will also need to add in any of your usual declarations for
-    Etherboot, e.g. 'filename "vmlinuz.ltsp";'.  Note that this setup
-    assumes that your DHCP server, TFTP server etc. all live on the
-    machine you are using for running Bochs.  If not, then you're on
-    your own.
-
-7.  As root, restart dhcpd
-      /etc/init.d/dhcpd restart
-
-8.  Build Etherboot images
-      pushd ../../src
-      make bin/pnic.dsk
-      popd
-
-9.  Start Bochs
-      ./bochs/bochs -q
-    You should get to the debugger prompt "<bochs:1>".  Type "c" to
-    start running Bochs.
-
-You should see Bochs start up, load up Etherboot and attempt to boot
-from the network.
-
-
-
-Serial console
-==============
-
-You can use the program "serial-console" to obtain a virtual serial
-console for Etherboot running within Bochs.  Simply run
-"./serial-console" on a spare tty (e.g. a separate xterm window)
-before starting Bochs, and ensure that you have enabled CONSOLE_SERIAL
-in config.h.
-
-There is a manual page for "serial-console"; use
-"man ./serial-console.1" to view it.
-
-
-
-TODO
-====
-
-Packet forwarding/masquerading - document what must be set up.
-
-Mention possibility of using RFB as the display device - in
-conjunction with the serial console, gives you a test facility that
-can be accessed remotely.
-
-Mention use of BOCHSBP instruction (xchgw %bx,%bx) to avoid need to
-calculate breakpoints.

-Running Etherboot within qemu
-=============================
-
-Michael Brown <mbrown@fensystems.co.uk>
-
-To get qemu running is fairly simple:
-
-1.  Build the utilities in this directory:
-      make
-
-2.  Get the qemu source code:
-      cvs -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/qemu \
-           login
-      cvs -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/qemu \
-           co qemu
-
-2a. Patch the qemu code.  There is currently a bug that causes qemu to
-    execute Etherboot incredibly slowly.  The bug seems to be related
-    to the relative prioritisation of CPU and I/O operations within
-    qemu.  This patch (which I found via Google) isn't a proper fix,
-    but it does work around the problem:
-      patch -p0 < qemu-patch
-
-3.  Configure qemu with
-      pushd qemu
-      ./configure --enable-system
-      popd
-
-    Note that qemu will not compile with gcc4; if your system's
-    default compiler is gcc4 then specify the path to gcc3 using
-    e.g. --cc=gcc-3.3.6
-
-4.  Build qemu:
-      make -C qemu
-
-5.  As root, set up a TAP virtual network device:
-      /sbin/modprobe tun
-      chmod o+rw /dev/net/tun

-    your own.
-
-7.  As root, restart dhcpd
-      /etc/init.d/dhcpd restart
-
-8.  Build Etherboot floppy disk images and pad to 1.44MB
-      pushd ../../src
-      make bin/rtl8139.pdsk
-      popd
-
-9.  Start qemu

-When serial-console starts, it will print out the message "Slave pty
-is /dev/pts/XX", where XX is a number.  You need to append the option
-

-Debugging Windows Remote Installation Services (RIS) can be
-problematic.  Here are some assorted notes on the process:
-
-
-Getting hold of the files
-=========================
-
-Add/Remove Windows Components -> Remote Installation Services
-
-Files will be placed in \windows\system32\reminst.  Copy them out to a
-TFTP server.  Configure DHCP to hand out startrom.com.
-
-
-Getting past the "Press F12" message
-====================================
-
-Passing F12 through to the guest machine is difficult.  It's easier to
-patch the startrom.com binary to accept a different key.  Open
-startrom.com in a hex editor, search for the hex string
-6681fb00860000, and replace it with 6681fb66210000.  startrom.com will
-now accept the "F" key instead of "F12".
-
-
-
-DHCP filename
-=============
-
-Must use Windows backslash separator e.g. 'filename
-"OSChooser\\i386\\startrom.com";', otherwise startrom.com fails to
-correctly identify the path to NTLDR.

-#=======================================================================
-# CONFIG_INTERFACE
-#
-# The configuration interface is a series of menus or dialog boxes that
-# allows you to change all the settings that control Bochs's behavior.
-# There are two choices of configuration interface: a text mode version
-# called "textconfig" and a graphical version called "wx".  The text
-# mode version uses stdin/stdout and is always compiled in.  The graphical
-# version is only available when you use "--with-wx" on the configure 
-# command.  If you do not write a config_interface line, Bochs will 
-# choose a default for you.
-#
-# NOTE: if you use the "wx" configuration interface, you must also use
-# the "wx" display library.
-#=======================================================================
-#config_interface: textconfig
-#config_interface: wx
-
-#=======================================================================
-# DISPLAY_LIBRARY
-#
-# The display library is the code that displays the Bochs VGA screen.  Bochs 
-# has a selection of about 10 different display library implementations for 
-# different platforms.  If you run configure with multiple --with-* options, 
-# the display_library command lets you choose which one you want to run with.
-# If you do not write a display_library line, Bochs will choose a default for
-# you.
-#
-# The choices are: 
-#   x              use X windows interface, cross platform
-#   win32          use native win32 libraries
-#   carbon         use Carbon library (for MacOS X)
-#   beos           use native BeOS libraries
-#   macintosh      use MacOS pre-10
-#   amigaos        use native AmigaOS libraries
-#   sdl            use SDL library, cross platform
-#   svga           use SVGALIB library for Linux, allows graphics without X11
-#   term           text only, uses curses/ncurses library, cross platform
-#   rfb            provides an interface to AT&T's VNC viewer, cross platform

-#
-# NOTE: if you use the "wx" configuration interface, you must also use
-# the "wx" display library.

-# ROMIMAGE:
-# The ROM BIOS controls what the PC does when it first powers on.
-# Normally, you can use a precompiled BIOS in the source or binary
-# distribution called BIOS-bochs-latest. The ROM BIOS is usually loaded
-# starting at address 0xf0000, and it is exactly 64k long.
-# You can also use the environment variable $BXSHARE to specify the
-# location of the BIOS.
-# The usage of external large BIOS images (up to 512k) at memory top is
-# now supported, but we still recommend to use the BIOS distributed with
-# Bochs. Now the start address can be calculated from image size.
-#=======================================================================
-romimage: file=bochs/bios/BIOS-bochs-latest, address=0xe0000
-#romimage: file=mybios.bin, address=0xfff80000 # 512k at memory top
-#romimage: file=mybios.bin # calculate start address from image size
-
-#=======================================================================
-# CPU:
-# This defines cpu-related parameters inside Bochs:
-#
-#  COUNT:
-#  Set the number of processors:cores per processor:threads per core 
-#  when Bochs is compiled for SMP emulation.
-#  Bochs currently supports up to 8 threads running simultaniosly. 
-#  If Bochs is compiled without SMP support, it won't accept values 
-#  different from 1.
-#
-#  RESET_ON_TRIPLE_FAULT:
-#  Reset the CPU when triple fault occur (highly recommended) rather than
-#  PANIC. Remember that if you trying to continue after triple fault the 
-#  simulation will be completely bogus !
-#
-#  IPS:
-#  Emulated Instructions Per Second.  This is the number of IPS that bochs
-#  is capable of running on your machine. You can recompile Bochs with
-#  --enable-show-ips option enabled, to find your workstation's capability.
-#  Measured IPS value will then be logged into your log file or status bar
-#  (if supported by the gui).
-#
-#  IPS is used to calibrate many time-dependent events within the bochs 
-#  simulation.  For example, changing IPS affects the frequency of VGA
-#  updates, the duration of time before a key starts to autorepeat, and
-#  the measurement of BogoMips and other benchmarks.
-#
-#  Examples:
-#  Machine                                         Mips
-# ________________________________________________________________
-#  2.1Ghz Athlon XP with Linux 2.6/g++ 3.4         12 to 15 Mips

-# Point this at a hard disk image file, cdrom iso file, or physical cdrom
-# device.  To create a hard disk image, try running bximage.  It will help you
-# choose the size and then suggest a line that works with it.
-#
-# In UNIX it may be possible to use a raw device as a Bochs hard disk, 
-# but WE DON'T RECOMMEND IT.  In Windows there is no easy way.
-#
-# In windows, the drive letter + colon notation should be used for cdroms.
-# Depending on versions of windows and drivers, you may only be able to 
-# access the "first" cdrom in the system.  On MacOSX, use path="drive"
-# to access the physical drive.
-#
-# The path is always mandatory. For flat hard disk images created with
-# bximage geometry autodetection can be used (cylinders=0 -> cylinders are
-# calculated using heads=16 and spt=63). For other hard disk images and modes
-# the cylinders, heads, and spt are mandatory.
-#
-# Default values are:
-#   mode=flat, biosdetect=auto, translation=auto, model="Generic 1234"
-#
-# The biosdetect option has currently no effect on the bios

-# BOOT:
-# This defines the boot sequence. Now you can specify up to 3 boot drives.
-# You can either boot from 'floppy', 'disk' or 'cdrom'
-# legacy 'a' and 'c' are also supported
-# Examples:
-#   boot: floppy
-#   boot: disk
-#   boot: cdrom
-#   boot: c
-#   boot: a
-#   boot: cdrom, floppy, disk

-# CLOCK:
-# This defines the parameters of the clock inside Bochs:
-#
-#  SYNC:
-#  TO BE COMPLETED (see Greg explanation in feature request #536329)
-#
-#  TIME0:
-#  Specifies the start (boot) time of the virtual machine. Use a time 
-#  value as returned by the time(2) system call. If no time0 value is 
-#  set or if time0 equal to 1 (special case) or if time0 equal 'local', 
-#  the simulation will be started at the current local host time.
-#  If time0 equal to 2 (special case) or if time0 equal 'utc',
-#  the simulation will be started at the current utc time.
-#
-# Syntax:
-#  clock: sync=[none|slowdown|realtime|both], time0=[timeValue|local|utc]
-#
-# Example:
-#   clock: sync=none,     time0=local       # Now (localtime)
-#   clock: sync=slowdown, time0=315529200   # Tue Jan  1 00:00:00 1980

-# LOG:
-# Give the path of the log file you'd like Bochs debug and misc. verbiage
-# to be written to. If you don't use this option or set the filename to
-# '-' the output is written to the console. If you really don't want it,
-# make it "/dev/null" (Unix) or "nul" (win32). :^(
-#
-# Examples:
-#   log: ./bochs.out
-#   log: /dev/tty
-#=======================================================================
-#log: /dev/null
-log: bochsout.txt
-
-#=======================================================================
-# LOGPREFIX:
-# This handles the format of the string prepended to each log line.
-# You may use those special tokens :
-#   %t : 11 decimal digits timer tick
-#   %i : 8 hexadecimal digits of cpu current eip (ignored in SMP configuration)
-#   %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
-#   %d : 5 characters string of the device, between brackets
-# 
-# Default : %t%e%d
-# Examples:
-#   logprefix: %t-%e-@%i-%d
-#   logprefix: %i%e%d
-#=======================================================================
-#logprefix: %t%e%d
-
-#=======================================================================
-# LOG CONTROLS
-#
-# Bochs now has four severity levels for event logging.
-#   panic: cannot proceed.  If you choose to continue after a panic, 
-#          don't be surprised if you get strange behavior or crashes.
-#   error: something went wrong, but it is probably safe to continue the
-#          simulation.
-#   info: interesting or useful messages.
-#   debug: messages useful only when debugging the code.  This may
-#          spit out thousands per second.
-#
-# For events of each level, you can choose to crash, report, or ignore.
-# TODO: allow choice based on the facility: e.g. crash on panics from
-#       everything except the cdrom, and only report those.
-#
-# If you are experiencing many panics, it can be helpful to change
-# the panic action to report instead of fatal.  However, be aware
-# that anything executed after a panic is uncharted territory and can 
-# cause bochs to become unstable.  The panic is a "graceful exit," so
-# if you disable it you may get a spectacular disaster instead.
-#=======================================================================
-panic: action=ask
-error: action=report
-info: action=report
-debug: action=ignore
-#pass: action=fatal
-
-#=======================================================================
-# DEBUGGER_LOG:
-# Give the path of the log file you'd like Bochs to log debugger output.
-# If you really don't want it, make it /dev/null or '-'. :^(
-#
-# Examples:
-#   debugger_log: ./debugger.out
-#=======================================================================
-#debugger_log: /dev/null
-#debugger_log: debugger.out
-debugger_log: -
-
-#=======================================================================
-# COM1, COM2, COM3, COM4:
-# This defines a serial port (UART type 16550A). In the 'term' you can specify
-# a device to use as com1. This can be a real serial line, or a pty.  To use
-# a pty (under X/Unix), create two windows (xterms, usually).  One of them will
-# run bochs, and the other will act as com1. Find out the tty the com1
-# window using the `tty' command, and use that as the `dev' parameter.
-# Then do `sleep 1000000' in the com1 window to keep the shell from
-# messing with things, and run bochs in the other window.  Serial I/O to
-# com1 (port 0x3f8) will all go to the other window.
-# Other serial modes are 'null' (no input/output), 'file' (output to a file
-# specified as the 'dev' parameter), 'raw' (use the real serial port - under
-# construction for win32), 'mouse' (standard serial mouse - requires
-# mouse option setting 'type=serial' or 'type=serial_wheel') and 'socket'
-# (connect a networking socket).
-#
-# Examples:
-#   com1: enabled=1, mode=null
-#   com1: enabled=1, mode=mouse
-#   com2: enabled=1, mode=file, dev=serial.out
-#   com3: enabled=1, mode=raw, dev=com1
-#   com3: enabled=1, mode=socket, dev=localhost:8888
-#=======================================================================
-#com1: enabled=1, mode=term, dev=/dev/ttyp9
-
-
-#=======================================================================
-# PARPORT1, PARPORT2:
-# This defines a parallel (printer) port. When turned on and an output file is
-# defined the emulated printer port sends characters printed by the guest OS
-# into the output file. On some platforms a device filename can be used to
-# send the data to the real parallel port (e.g. "/dev/lp0" on Linux, "lpt1" on
-# win32 platforms).
-#
-# Examples:
-#   parport1: enabled=1, file="parport.out"
-#   parport2: enabled=1, file="/dev/lp0"
-#   parport1: enabled=0
-#=======================================================================
-parport1: enabled=1, file="parport.out"
-
-#=======================================================================
-# SB16:
-# This defines the SB16 sound emulation. It can have several of the
-# following properties.
-# All properties are in the format sb16: property=value
-# midi: The filename is where the midi data is sent. This can be a
-#       device or just a file if you want to record the midi data.
-# midimode:
-#      0=no data
-#      1=output to device (system dependent. midi denotes the device driver)
-#      2=SMF file output, including headers
-#      3=output the midi data stream to the file (no midi headers and no
-#        delta times, just command and data bytes)
-# wave: This is the device/file where wave output is stored
-# wavemode:
-#      0=no data
-#      1=output to device (system dependent. wave denotes the device driver)
-#      2=VOC file output, incl. headers
-#      3=output the raw wave stream to the file
-# log:  The file to write the sb16 emulator messages to.
-# loglevel:
-#      0=no log
-#      1=resource changes, midi program and bank changes
-#      2=severe errors
-#      3=all errors
-#      4=all errors plus all port accesses
-#      5=all errors and port accesses plus a lot of extra info
-# dmatimer:
-#      microseconds per second for a DMA cycle.  Make it smaller to fix
-#      non-continuous sound.  750000 is usually a good value.  This needs a
-#      reasonably correct setting for the IPS parameter of the CPU option.
-#
-# For an example look at the next line:
-#=======================================================================
-
-#sb16: midimode=1, midi=/dev/midi00, wavemode=1, wave=/dev/dsp, loglevel=2, log=sb16.log, dmatimer=600000
-
-#=======================================================================
-# VGA_UPDATE_INTERVAL:
-# Video memory is scanned for updates and screen updated every so many
-# virtual seconds.  The default is 40000, about 25Hz. Keep in mind that
-# you must tweak the 'cpu: ips=N' directive to be as close to the number
-# of emulated instructions-per-second your workstation can do, for this
-# to be accurate.
-#
-# Examples:
-#   vga_update_interval: 250000
-#=======================================================================
-vga_update_interval: 300000
-
-# using for Winstone '98 tests
-#vga_update_interval:  100000
-
-#=======================================================================
-# KEYBOARD_SERIAL_DELAY:
-# Approximate time in microseconds that it takes one character to
-# be transfered from the keyboard to controller over the serial path.
-# Examples:
-#   keyboard_serial_delay: 200
-#=======================================================================
-keyboard_serial_delay: 250
-
-#=======================================================================
-# KEYBOARD_PASTE_DELAY:
-# Approximate time in microseconds between attempts to paste
-# characters to the keyboard controller. This leaves time for the
-# guest os to deal with the flow of characters.  The ideal setting
-# depends on how your operating system processes characters.  The
-# default of 100000 usec (.1 seconds) was chosen because it works 
-# consistently in Windows.
-#
-# If your OS is losing characters during a paste, increase the paste
-# delay until it stops losing characters.
-#
-# Examples:
-#   keyboard_paste_delay: 100000
-#=======================================================================
-keyboard_paste_delay: 100000
-
-#=======================================================================
-# MOUSE: 
-# This option prevents Bochs from creating mouse "events" unless a mouse
-# is  enabled. The hardware emulation itself is not disabled by this.
-# You can turn the mouse on by setting enabled to 1, or turn it off by
-# setting enabled to 0. Unless you have a particular reason for enabling
-# the mouse by default, it is recommended that you leave it off.
-# You can also toggle the mouse usage at runtime (control key + middle
-# mouse button on X11, SDL, wxWidgets and Win32).
-# With the mouse type option you can select the type of mouse to emulate.
-# The default value is 'ps2'. The other choices are 'imps2' (wheel mouse
-# on PS/2), 'serial', 'serial_wheel' (one com port requires setting
-# 'mode=mouse') and 'usb' (3-button mouse - one of the USB ports must be
-# connected with the 'mouse' device - requires PCI and USB support).
-#
-# Examples:
-#   mouse: enabled=1
-#   mouse: enabled=1, type=imps2
-#   mouse: enabled=1, type=serial
-#   mouse: enabled=0
-#=======================================================================
-mouse: enabled=0

-#=======================================================================
-# private_colormap: Request that the GUI create and use it's own
-#                   non-shared colormap.  This colormap will be used
-#                   when in the bochs window.  If not enabled, a
-#                   shared colormap scheme may be used.  Not implemented
-#                   on all GUI's.

-# Examples:
-#   private_colormap: enabled=1
-#   private_colormap: enabled=0

-# fullscreen: ONLY IMPLEMENTED ON AMIGA
-#             Request that Bochs occupy the entire screen instead of a 
-#             window.

-# ne2k: NE2000 compatible ethernet adapter
-#
-# Examples:
-# ne2k: ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE, script=SCRIPT
-#
-# ioaddr, irq: You probably won't need to change ioaddr and irq, unless there
-# are IRQ conflicts.
-#
-# mac: The MAC address MUST NOT match the address of any machine on the net.
-# Also, the first byte must be an even number (bit 0 set means a multicast
-# address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast
-# address.  For the ethertap module, you must use fe:fd:00:00:00:01.  There may
-# be other restrictions too.  To be safe, just use the b0:c4... address.
-#
-# ethdev: The ethdev value is the name of the network interface on your host
-# platform.  On UNIX machines, you can get the name by running ifconfig.  On
-# Windows machines, you must run niclist to get the name of the ethdev.
-# Niclist source code is in misc/niclist.c and it is included in Windows 
-# binary releases.
-#
-# script: The script value is optional, and is the name of a script that 
-# is executed after bochs initialize the network interface. You can use 
-# this script to configure this network interface, or enable masquerading.
-# This is mainly useful for the tun/tap devices that only exist during
-# Bochs execution. The network interface name is supplied to the script
-# as first parameter
-#
-# If you don't want to make connections to any physical networks,
-# you can use the following 'ethmod's to simulate a virtual network.
-#   null: All packets are discarded, but logged to a few files.
-#   arpback: ARP is simulated. Disabled by default.
-#   vde:  Virtual Distributed Ethernet
-#   vnet: ARP, ICMP-echo(ping), DHCP and read/write TFTP are simulated.
-#         The virtual host uses 192.168.10.1.
-#         DHCP assigns 192.168.10.2 to the guest.
-#         TFTP uses the ethdev value for the root directory and doesn't
-#         overwrite files.

-# KEYBOARD_MAPPING:
-# This enables a remap of a physical localized keyboard to a 
-# virtualized us keyboard, as the PC architecture expects.
-# If enabled, the keymap file must be specified.
-# 
-# Examples:
-#   keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map
-#=======================================================================
-keyboard_mapping: enabled=0, map=
-
-#=======================================================================
-# KEYBOARD_TYPE:
-# Type of keyboard return by a "identify keyboard" command to the
-# keyboard controler. It must be one of "xt", "at" or "mf".
-# Defaults to "mf". It should be ok for almost everybody. A known
-# exception is french macs, that do have a "at"-like keyboard.
-#
-# Examples:
-#   keyboard_type: mf
-#=======================================================================
-#keyboard_type: mf
-
-#=======================================================================
-# USER_SHORTCUT:
-# This defines the keyboard shortcut to be sent when you press the "user"
-# button in the headerbar. The shortcut string is a combination of maximum
-# 3 key names (listed below) separated with a '-' character. The old-style
-# syntax (without the '-') still works for the key combinations supported
-# in Bochs 2.2.1.
-# Valid key names:
-# "alt", "bksl", "bksp", "ctrl", "del", "down", "end", "enter", "esc",
-# "f1", ... "f12", "home", "ins", "left", "menu", "minus", "pgdwn", "pgup",
-# "plus", "right", "shift", "space", "tab", "up", and "win".
-#
-# Example:
-#   user_shortcut: keys=ctrl-alt-del
-#=======================================================================
-user_shortcut: keys=ctrl-alt-del
-
-#=======================================================================
-# I440FXSUPPORT:
-# This option controls the presence of the i440FX PCI chipset. You can
-# also specify the devices connected to PCI slots. Up to 5 slots are
-# available now. These devices are currently supported: ne2k, pcivga,
-# pcidev and pcipnic. If Bochs is compiled with Cirrus SVGA support
-# you'll have the additional choice 'cirrus'.
-#
-# Example:
-#   i440fxsupport: enabled=1, slot1=pcivga, slot2=ne2k
-#=======================================================================
-i440fxsupport: enabled=1, slot1=pcipnic
-#i440fxsupport: enabled=1, slot1=ne2k
-
-#=======================================================================
-# USB1:
-# This option controls the presence of the USB root hub which is a part
-# of the i440FX PCI chipset. With the portX option you can connect devices
-# to the hub (currently supported: 'mouse' and 'keypad'). If you connect
-# the mouse to one of the ports and use the mouse option 'type=usb' you'll
-# have a 3-button USB mouse.
-#
-# Example:
-#   usb1: enabled=1, port1=mouse, port2=keypad
-#=======================================================================
-#usb1: enabled=1
-
-#=======================================================================
-# CMOSIMAGE:
-# This defines image file that can be loaded into the CMOS RAM at startup.
-# The rtc_init parameter controls whether initialize the RTC with values stored
-# in the image. By default the time0 argument given to the clock option is used.
-# With 'rtc_init=image' the image is the source for the initial time.

-=head1 NAME
-
-serial-console
-
-=head1 SYNOPSIS
-
-serial-console [options]
-
-Options:
-
-    -h,--help         Display brief help message
-    -v,--verbose      Increase verbosity
-    -q,--quiet        Decrease verbosity
-    -l,--log FILE     Log output to file
-    -r,--rcfile	FILE  Modify specified bochsrc file
-
-=head1 DESCRIPTION
-
-C<serial-console> provides a virtual serial console for use with
-Bochs.  Running C<serial-console> creates a pseudo-tty.  The master
-side of this pty is made available to the user for interaction; the
-slave device is written to the Bochs configuration file
-(C<bochsrc.txt>) for use by a subsequent Bochs session.
-
-=head1 EXAMPLES
-
-=over 4
-
-=item C<serial-console>
-
-Create a virtual serial console for Bochs, modify C<bochsrc.txt>
-appropriately.
-
-=item C<serial-console -r ../.bochsrc -l serial.log>
-
-Create a virtual serial console for Bochs, modify C<../.bochsrc>
-appropriately, log output to C<serial.log>.
-
-=back
-
-=head1 INVOCATION
-
-Before starting Bochs, run C<serial-console> in a different session
-(e.g. a different xterm window).  When you subsequently start Bochs,
-anything that the emulated machine writes to its serial port will
-appear in the window running C<serial-console>, and anything typed in
-the C<serial-console> window will arrive on the emulated machine's
-serial port.
-
-You do B<not> need to rerun C<serial-console> afresh for each Bochs
-session.
-
-=head1 OPTIONS
-
-=over 4
-
-=item B<-l,--log FILE>
-
-Log all output (i.e. everything that is printed in the
-C<serial-console> window) to the specified file.
-
-=item B<-r,--rcfile FILE>
-
-Modify the specified bochsrc file.  The file will be updated to
-contain the path to the slave side of the psuedo tty that we create.
-The original file will be restored when C<serial-console> exits.  The
-default is to modify the file C<bochsrc.txt> in the current directory.
-
-To avoid modifying any bochsrc file, use C<--norcfile>.

-The  compressor achieves  an  average compression  rate of 60%  of the
-original size which is on par with "gzip". It seems that you cannot do
-much better for compressing  compiled  binaries.  This means that  the
-break even  point  for using compressed  images is   reached, once the
-uncompressed size approaches 1.5kB. We  can stuff more than 12kB  into
-an 8kB EPROM and more than 25kB into an 16kB EPROM.   As there is only
-32kB of RAM  for both the uncompressed  image  and its BSS  area, this
-means that 32kB EPROMs will hardly ever be required.
-
-The compression  algorithm uses a  4kB  ring buffer  for buffering the
-uncompressed data. Before   compression starts,  the  ring buffer   is
-filled  with spaces (ASCII  character  0x20).  The algorithm tries  to
-find repeated  input sequences of a  maximum length of  60 bytes.  All
-256 different input  bytes  plus the 58 (60   minus a threshold of  2)
-possible  repeat lengths form a set  of 314 symbols. These symbols are
-adaptively Huffman encoded.  The  algorithm starts out with a Huffmann
-tree  that  assigns equal code lengths    to each of  the  314 symbols
-(slightly favoring the repeat  symbols over symbols for regular  input
-characters), but  it will be changed whenever  the frequency of any of
-the symbols  changes. Frequency counts are  kept in 16bit  words until
-the total number of compressed codes totals 2^15.  Then, all frequency
-counts will be halfed (rounding to the bigger number).  For unrepeated
-characters (symbols 0..255) the Huffman code  is written to the output
-stream.  For repeated characters the  Huffmann code, which denotes the
-length of the repeated character sequence, is written out and then the
-index in the ring buffer is computed.   From this index, the algorithm
-computes  the offset   relative to  the current  index  into  the ring
-buffer. Thus,  for typical input data,  one would expect that short to
-medium range offsets are more frequent  than extremely short or medium
-range to long range offsets. Thus the  12bit (for a 4kB buffer) offset
-value  is statically Huffman encoded  using a precomputed Huffman tree
-that favors  those  offset  values    that  are deemed to   be    more
-frequent. The  Huffman encoded offset  is  written to the output  data
-stream,  directly  following the code  that   determines the length of
-repeated characters.
-
-This algorithm, as implemented in the  C example code, looks very good
-and  its operating parameters are   already well optimized. This  also
-explains   why  it achieves     compression ratios    comparable  with
-"gzip". Depending on the input data, it sometimes excells considerably
-beyond what "gzip -9" does, but this  phenomenon does not appear to be
-typical. There are some flaws with  the algorithm, such as the limited
-buffer  sizes, the  adaptive  Huffman tree  which takes  very  long to
-change, if    the input  characters  experience   a sudden   change in
-distribution, and the static Huffman   tree for encoding offsets  into
-the  buffer.   The slow  changes of   the  adaptive  Huffman  tree are
-partially counteracted by  artifically keeping  a 16bit precision  for
-the frequency counts, but  this does not  come into play until 32kB of
-compressed data is output, so  it does not  have any impact on our use
-for "etherboot", because  the BOOT Prom  does not support uncompressed
-data of more then 32kB (c.f. doc/spec.doc).
-
-Nonetheless,  these problems  do  not  seem  to affect  compression of
-compiled  programs very much.  Mixing  object code with English  text,
-would not work too  well though, and  the algorithm should be reset in
-between. Actually, we  might  gain a little  improvement, if  text and
-data   segments    were compressed  individually,    but   I have  not
-experimented with this option, yet.

-Subject: [Etherboot-users] Example ISC DHCP v3 dhcpd.conf using conditional operations
-Date: Wed, 13 Jun 2001 20:22:21 -0600
-
-Hopefully someone will find this useful.  I spent a long time tracking
-down and figuring out all the pieces.  To the powers that be, feel free to
-stick this in contrib if you like it.
-
-Goal:  Use the vendor-class-identifier and ISC DHCP v3 "match" option to
-conditionally send proper options only when the DHCP discover/request from
-etherboot comes in.  We use static-MAC-to-IP mappings for classroom
-computers, and dynamic dhcp ranges for other clients (student laptops,
-etc).
-
-I used Etherboot 5.0.1 and the patch (required) in this email:
-
-http://www.geocrawler.com/lists/3/SourceForge/5299/0/5952625/
-
-Furture versions of Etherboot will likely already have this patch
-included.

-Ok, here is a diff for etherboot 4.6.0 that adds identifiers.
-
-To test this you need to use a class in the dhcpd.conf file and
-also send back a string in option 208.
-
-These identifiers prevent a client from booting from other DHCP
-servers when you have more than 1 in your network.
-
-In will also prevent any client, except the valid ones, to use this
-DHCP server.
-
-Here is a subset of my dhcpd.conf :
-
-option iNdiskless-state code 208 = text;
-
-class "iNdiskless-boot" {
-    match if substring(option iNdiskless-state,0,4) = "BOOT";
-}
-class "iNdiskless-setup" {

-Hello!
-
-When Intel eepro100+ NIC disappeared from the market, I didn't know
-what to do. I didn't find any information if anyone has used the
-new eepro100+ Management Adapter to netboot linux. 
-
-I thought that the card should netboot with the same configuration as
-the old card when I read Donald Beckers comment:
-> The driver should "just work" with the '559. It's not supposed to be
-> substantially different than the '558. (I don't have a datasheet
-> or sample card to confirm this statement.)
-
-The problem was now only to put the netboot-program to the built in
-flash memory on the NIC. With the old card I used a flash memory (Intel
-N28F020 [N28010 didn't work])) and the program FUTIL.EXE from Intel to
-flash it. FUTIL did't recognize the memory on the management card
-and did not work therefore.
-
-I found the intel program FBOOT.EXE that was made to upgrade the built
-in Intel BOOT agent. I did: Boot dos from floppy, Run FBOOT (choose
-adapter), choose (u)pdate, choose Create restore image, rename the
-backup file (in my case 2743BE52.FLS [the eight last hex digits from
-the MAC address]), rename your netboot code (in my case netboot 0.8.1)
-to the backup files original name (in my case 2743BE52.FLS), run
-FBOOT, choose (r)estore.
-
-Voila!
-
-A shorter way (if you don't need the backup of the old Intel BOOT
-agent code) is of course: rename netboot file to [the eight last hex
-digits from the MAC address].FLS, run FBOOT, choose restore.
- 
-Caution: I think it is possible to make a NIC unusable if you have
-made the netboot (or etherboot) file with "wrong" parameters. A couple
-of month ago I did a etherboot boot file and put it on an old
-EEPRO100+ card. It worked fine, but it was impossible to boot local
-with it. So I could not boot dos and with FUTIL or FBOOT erase the
-flash memory!  To erase the chip I had to take out the memory chip,
-boot dos and then put in the memory chip. This isn't possible when the
-memory chip is build in.

-Subject: Look Mom, no PROM burner! (eepro100b flashing instructions) :-)

-Continuing the Etherboot World Domination theme, I noticed that there was 
-a PCI ethernet card on my bookshelf that still contained the original 
-vendor's code in its flash memory.  The card virtually cried out to be 
-flashed with Etherboot 4.4.1. :-)
-
-After having figured out how to flash the 3C905C last week, and owing to 
-the fact that the temperature here in Cambridge, Massachusetts (USA) has 
-dropped well below freezing, I decided to explore the possibility of 
-flashing the Intel eepro100b that was sitting on my bookcase.
-
-After determining that it was unlikely that one could flash the chip in 
-user mode under linux like the 3C509C,  I turned to other options.  (the 
-reason is that the flash is memory mapped to a place that causes a core 
-dump if accessed.  i suppose one could to patch the kernel to flash the 
-card, or add a linux device driver, but... :-)  
-
-By the way, If you are ever looking for Linux utilities for Ethernet 
-cards, you may want to check out: 
-
-   http://cesdis.gsfc.nasa.gov/linux/diag/
-
-which is a treasure trove of tools for manipulating and testing Ethernet 
-cards, all with source, courtesy of Donald Becker.
-
-At this point, I felt it was time to make a virtual trip to the Intel 
-site (http://www.intel.com/), and search for utilities that might work 
-with the eepro100B.  I found two candidates:  FUTIL and FBOOT.  I 
-downloaded, decompressed, and transferred them to a DOS formatted floppy. 
-Next I determined (after a few tries) that F8 will let me get to DOS 
-instead of booting windows. (I tend to avoid Windows when I can).
-
-I first tried FUTIL.EXE.  No good.  It told me it didn't recognize the 
-flash on my eepro100B.  how unfortunate.  and I had such hopes :-)
-
-Next I tested FBOOT.EXE  (available at 
-http://support.intel.com/support/network/adapter/pro100/100PBOOT.htm)  
-This program did in fact recognize my eepro100b card.
-
-The thing about FBOOT however, is that it thinks it only can load certain 
-files.  I of course needed to load an Etherboot image.  It appeared to 
-have no option for doing that.  Things looked grim.
-
-Then I noticed that FBOOT was kind enough to do the following dialog:
-
-   Select Option (U)pdate or (R)estore: U
-
-I chose Update and it then offered to back up my flash rom for later 
-restore:
-
-   Create Restore Image (Y)es or (N)o: Y
-
-I chose "Y" and it proceeded to write a file of my flash memory, which 
-contained the Intel code.
-
-   Writing FLASH image to file... 100%
-
-It then erased the device:
-
-   Erasing FLASH Device... 100%
-
-and then programmed it with fresh code (stored inside the program, no 
-doubt):
-
-   Programming FLASH Device... 100%
-
-So now I had a backup of the Intel boot code in a file strangely called:
-
-   2794FC60.FLS
-
-Hmmmm, interesting name.  The MAC address of the card is 09902794FC60.  
-They just name the file with the last 4 octets of the MAC address and 
-.FLS.  The file is exactly 65536 bytes, which would make sense for a 64K 
-Flash Memory device.
-
-Then I got to thinking, I wonder how carefully the "restore" part of 
-FBOOT looks at what it is loading?  What if I took an Etherboot .rom 
-file, padded it with 48K of 0xFFs and named it 2794FC60.FLS.  What if I 
-then told FBOOT.EXE to "restore" that?
-
-Well, I guess by now, you know it worked :-) 
-
-The card came up with the delightful Etherboot banner, Did DHCP, tftp, 
-and started a kernel.
-
-The only unfortunate part is that you need to do this under DOS because 
-you seem to need to be in real mode to program the card.  Oh well, 
-sacrifices have to be made :-)
-
-So, in summary, to prepare Etherboot image for flashing into the Intel 
-EEPRO100B card with FBOOT, you need to first make an eepro100.rom file, 
-as usual.
-
-Then, see how large it is, with an "ls -l eepro100.rom". the answer will 
-probably be 16,384.  You need to pad it with hex FFs to make it 64K for 
-FBOOT.  I used the following two lines to create the flash image file.
-
-   $ perl -e 'print "\xFF" x 49152' > 48kpad.bin
-   $ cat eepro100.rom 48kpad.bin > 2794FC60.FLS
-
-Next write it to a DOS Floppy:
-
-   $ mount -t msdos /dev/fd0 /mnt/floppy
-   $ cp 2794FC60.FLS /mnt/floppy
-   $ umount /mnt/floppy
-
-Now you need to get to DOS.  You could actually use a bootable DOS floppy 
-with FBOOT.EXE and 2794FC60.FLS on it.  I started a Windows box and hit 
-F8 right before Windows started, and chose option 5, "Command Prompt 
-Only", which gives you DOS.  This program can't run in a DOS window under 
-Windows or anything like that.  You need to be in real DOS.
-
-Next it's time to run FBOOT.  It will detect your ethernet card(s), ask 
-you which one you want to program, and let you choose it from a menu.
-
-now the fun part:
-
-   Select Option (U)pdate or (R)estore: R
-   Erasing FLASH Device... 100%
-   Writing FLASH image from file... 100%
-
-Time to reboot and let Etherboot take over.
-
-So there you go, a way to make Intel EEPRO100Bs play nicely with 
-Etherboot.  Maybe we should put these instructions in the Etherboot 
-contrib directory so people who have eepro100b cards will be able to 
-avoid 3C905C envy :-)
-
-I hope this helps a few people out.
-
-Regards,
-
-Marty

-Hello!
-
-In <http://www.han.de/~gero/netboot/archive/msg01718.html> I wrote what I
-did know about futil and fboot then. It is about the same as Martys
-instructions, but I have a few comments now.
-
-> Then, see how large it is, with an "ls -l eepro100.rom". the answer will

->   $ cat eepro100.rom 48kpad.bin > 2794FC60.FLS
-
-It worked for me without any padding. When I burned a smaller image
-the program printed 50% instead of 100% and then it
-stopped. Everything worked anyway.
-
-
-I also did a brutal way of install etherboot or netboot on a
-EEPRO100+Mng without creating a file of type "2794FC60.FLS" for
-every card. It was necessary for me when I installed 70 clients...
-
-I chopped the binary file fboot.exe (my version was 99811 bytes, I
-don't remember the version name) in three parts:
-
-fboot1 30096 bytes
-fboot2 65536 bytes
-fboot3 4179  bytes
-
-Then you cat put them together again, but with a different part 2 and
-save it as fbootown.exe and execute it. It worked for me anyway. Of
-course you have to use padding to get a 64k part instead of fboot2.

-Error Code Lookup for gPXE
-==========================
-This program looks up gPXE error codes so you can locate the line of source
-code which produced the error.
-
-Setup
------
-You must run:
-./build_errcodedb.py >errcodedb.py
-
-This extracts error code definitions from the gPXE source code and produces a
-"database" which is used by the main program.
-
-Once you have done this errcode.py and errcodedb.py are the only files you
-need.  They are now independent of the gPXE source code and can be moved
-anywhere.
-
-[OPTIONAL]
-A PHP script is provided as a web interface.  First edit errcode.php to point
-$ERRCODE_PATH to the errcode.py script.  Then move errcode.php to a location
-visible from your web server.
-
-[OPTIONAL]
-A simple IRC bot is provided.  Edit gpxebot.py to fill in the IRC details.
-
-Usage
------
-Looking up error codes on the command-line:
-./errcode.py 0x12345678
-
-Further information
--------------------
-See http://etherboot.org/.

-It is good joke, at this moment I have only simple version of MBR to load
-image from HD, but only from track 0. HD have to have enough sectors per
-track for rom image.
-And small program in turbo-pascal to download image to HD.
-
-below is assembler code for MBR. Is writen for tasm and tlink. 
-If you have 512 bytes binary file with MBR code, then concat it with
-rom-image and download to hda. BUT NOT DIRECTLY !!!! You have to copy 
-partition table ( and NT signature ) to MBR and then download. BUT ONLY tO
-TRACK 0.
-
-Everything in your own risk.
-
-If I will have some free time, I will write some code directly to netboot.

-README for mkinitrd-net
-
-mkinitrd-net enables you to use your distribution's stock kernel for
-diskless workstations, without having to compile in support for the
-relevant network card(s).  It creates an initial ramdisk image containing
-the required network-card kernel modules and bootstrap scripts to load the
-module, obtain an IP address via DHCP and mount the root filesystem via
-NFS.
-
-mkinitrd-net also generates a dhcpd.conf file fragment that can be used to
-automate the process of mapping NBI files to clients, based on the PCI IDs
-of their network cards.  Etherboot will send the PCI ID of the network
-card to the DHCP server in the etherboot-encapsulated-options field
-(Etherboot 5.0.7 and newer) and the DHCP server can use this to identify
-the correct NBI to point the client towards.
-
-The end result is that:
-
-a) You can avoid the hassle of compiling custom kernels for diskless
-   workstations.
-
-b) Diskless workstations will automatically download the correct
-   kernel+initrd.
-
-c) You have an easier life! :-)

-%description
-mkinitrd-net allows you to build initial ramdisk images (initrds) suitable
-for use with Etherboot and other network-booting software.  This package
-contains two main utilities: mkinitrd-net (to build an initrd containing a
-specified set of network-card modules) and mknbi (to generate
-Etherboot-usable NBI images from a given kernel and initrd).  It also
-contains a helper script mknbi-set which will maintain sets of initrds to
-match all your currently-installed kernels.
-
-mkinitrd-net uses code from the uClibc, busybox, udhcp and Etherboot
-projects.

------BEGIN PGP SIGNED MESSAGE-----
-
-linux-2.0.21-transname.patch enables diskless clients, X-terminals etc to
-mount the *root filesystem* of the server. This makes administration of
-large pools *a lot* easier.
-
-Currently different diskless clients must have their root "/" on different
-directories on the server, beause each client has _some_ different
-configuration files. However, most administration files (typically about 99%)
-have the same contents on the clients and on the server, but have to be
-(and maintained separately) just because of the 1% differences.
-
-This duplication causes very large efforts in practice, since at least
-the /etc directory has to be duplicated for every client. Even in /etc
-many files are identical, for example sendmail.cf, initrc scripts and
-others. Maintaining a large pool means to ensure coherence amoung the
-duplicates. Classical methods like symlinks are unconvenient
-for this task because they have to be valid in the view of mounted
-filesystems at the client, not at the server.
-
-linux-2.0-transname.patch overcomes this problem by allowing filenames
-to be context-dependend. For example, if you have a file "/etc/config"
-that should differ on the hosts "myserver" and "myclient", you just
-create two different files named "/etc/config#host=myserver#" and
-"/etc/config#host=myclient#". On host "myserver", the file
-"/etc/config#host=myserver#" will appear as if it were hardlinked to
-file "/etc/config" (without the #...=...# suffix). On host "myclient",
-the corresponding other file will appear as "/etc/config". So you
-can access the right file contents under the same name, depending
-on which host you are.
-
-As a result, you may use different contexts for e.g. /etc/fstab, but
-have one shared /etc/passwd for all pool machines. So you don't need
-yp or NYS any more.
-
-The kernel patch was developped for and is used at our Linux pool at the
-University of Stuttgart with good results. Maintainance of the pool is
-at a minimum, and adding new clients is a child's play. No worry with
-keeping up mail configurations, newly installed tools, changed /etc/services,
-/etc/shells, /etc/resolv.conf and many, many others. In contrast to a
-sophisticated symlink solution, adding a new file to the /etc directory
-is seen immediately by all clients. I never had less trouble with
-administration before.
-
-I just uploaded the patch to
-  ftp://ftp.lmh.ox.ac.uk
-         where it should appear in /pub/linux-kernel-patch-archive/
-and also to
-  ftp://sunsite.unc.edu/pub/Linux/Incoming/
-         where it should be moved to /pub/Linux/kernel/patches/misc/ soon.
-
-More details can be found in the README there, and also in the
-configure-help.
-
-Enjoy,
-

-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                          675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>

-mkQNXnbi is a quick hack to generate tagged images from QNX boot images.
-
-To boot a QNX client with Etherboot you have to consider the following:
-1. You MUST have another QNX box running in the network to provide the
-   root filesystem and the license info to the client. QNX cannot use
-   e.g. NFS for its root filesystem, as it needs to load a valid license
-   from a file on the root fs before being able to start TCP/IP. This
-   would lead to a chicken-and-egg problem.
-2. The Net task normally determines the size of its internal tables from
-   the actual number of licensed nodes. Since this information is not
-   available at boot time when booting from the network, you will have
-   to set the max. number of nodes as well as a valid netmap entry for
-   the node providing the root filesystem as an option to Net in the
-   build file.
-   See examples/ws.etherboot and fill in the <blanks>.
-3. The client does not need a TCP/IP license in order to boot.
-4. You can use the boot-server OS of your choice. If you choose to use
-   QNX as boot server, the server of course needs a TCP/IP run-time
-   license.  In this case you have the option of creating the boot image
-   on-the-fly and use the macro $(netmap) instead of a hard-coded MAC
-   address.
-   See examples/ws.etherboot.on-the-fly and fill in the <blanks>.
-   A template bootptab for the QNX bootp server is placed in the
-   examples directory.
-5. mkQNXnbi expects the QNX image to be supplied on stdin and generates
-   the tagged image to stdout. This can be overridden on the command line
-   using the options -i <input-file> and -o <output-file>.
-
-mkQNXnbi can be compiled using e.g. Linux/gcc or on QNX using Watcom C
-(or gcc, if you have it - see http://w3c.teaser.fr/~jcmichot/)

-This is a quick and dirty script to convert a floppyfw floppy
-(http://www.zelow.no/floppyfw/) to a tagged image for booting with
-Etherboot (http://etherboot.sourceforge.net/). The advantages of network
-booting include: it's much faster loading from the network than from a
-floppy disk, you can boot from any size floppy, and you are not limited
-to the maximum of 1.44 MB of the physical floppy. If you have enough RAM
-and use a virtual floppy to build the initial boot image, you can put as
-much on it as will fit the ramdisk.
-
-See further down under -nonet if you want to boot from HD or CDROM.
-
-This program requires mtools, tar, bzip2, loopback mount in the kernel,
-and root privileges to execute. Hope you have them.
-
-This script works for any of the releases for which a subdirectory of
-that name is provided, but it should not be too hard to make it work for
-other releases, all that is done here is to substitute some scripts for
-the distributed ones.
-
-First of all you should make the floppy work the way you want before
-converting it to a tagged image. This involves editing the various
-config files on the floppy. Instructions on this are distributed from
-the floppyfw web page mentioned above.
-
-Edit the $tftpdir assignment for the directory where you put your tagged
-images.  Edit the $libdir assignment and the use lib directive near the
-top if you decide to put this package somewhere other than
-/usr/local/lib/mkffwnb/. Adjust the instructions below as necessary.
-
-Copy everything to $libdir.
-
-	mkdir -p /usr/local/lib/mkffwnb/
-	cp -a . /usr/local/lib/mkffwnb/
-
-Make a link from /usr/local/lib/mkffwnb/mkffwnb.pl to
-/usr/local/bin/mkffwnb so that it's in your path.
-
-	ln -s /usr/local/lib/mkffwnb/mkffwnb.pl /usr/local/bin/mkffwnb
-
-Then run it as:
-
-	mkffwnb
-
-You can also provide a floppy drive as an argument, e.g.
-
-	mkffwnb x:
-
-where x: could be mapped to a disk file. This allows you to build an
-image without a real floppy drive. Remember that for virtual drives root
-must have the mapping for the drive in question in ~root/.mtoolsrc.
-
-You can use the option --localtime=/etc/localtime to specify that the
-file /etc/localtime is to be copied to /etc/localtime on the initrd.
-Instead of /etc/localtime, you can use any of the timezone files under
-/usr/share/zoneinfo/, it's just that /etc/localtime will usually be the
-correct one for your timezone.
-
-If you use the option -nonet, it leaves the intermediate files in
-$tempdir, /tmp/mkffwnb by default. This is useful if you want the
-vmlinuz and initrd.gz files for use with LILO or isolinux to boot from
-HD or CDROM. Actually you can also use these with a floppy, it loads
-faster if you fold all the scripts and modules into the initrd ahead
-of time.
-
-mkffwnb has to be run as root because it uses loopback mounts and also
-because the files inside the initrd are owned by root.

-#
-# Perl script to make a bootable image from a floppyfw floppy
-# The basic idea is to unpack and replace or convert all
-# the necessary config files into the initrd
-# and then make a bootable image out of it
-#
-# The --format= option overrides the default of nbi or elf hardcoded
-# in the source. Valid arguments are nbi or elf.
-#
-# The --output= options specifies an output file instead of stdout
-# The --nonet option specifies that a netbootable image is not to
-# be built but the vmlinuz and initrd.gz files left behind in $tempdir
-# The --localtime=f option specifies a timezone file that's to be
-# copied to /etc/localtime in the initrd, allowing a different timezone.
-# The --ffw29 option is intended for 2.9.x and above and extends
-# the size of the initrd by making a bigger one and copying the original over.
-#
-# The first non-option argument is taken to be the letter of a floppy to
-# convert, e.g. a:, b: or even x: where x: is mapped to a file using
-# mtools mapping in $HOME/.mtoolsrc. See the mtools documentation.
-# Thus you can work on a floppy image in a disk file and only write
-# to a floppy with dd or cp when you need to test the image.

-It is primarily intended for diskless Linux hosts running as printer drivers
-but there is no reason why it could not be used on diskful hosts.
-Port 9100 is copied to /dev/lp0, 9101 to /dev/lp1 and 9102 to /dev/lp2.
-The default is port 9100 to /dev/lp0.
-.LP
-The \fB-f\fR option can be used to specify a different printer device,
-e.g. /dev/usblp0.
-.LP
-The \fB-i\fR option can be used to specify binding to one address instead
-of all interfaces which is the default.
-.LP
-The \fB-b\fR option turns on bidirectional copying.
-.LP
-The \fB-v\fR option shows the version number.
-.SH INSTALLATION
-.I p910nd
-can be run as a standalone daemon or from inetd.
-It will automatically detect if it is running under inetd.
-.LP
-A sample SysVinit script,
-.IR p910nd.sh ,
-is provided for operation as a daemon.
-.I p910nd
-will change its name under ps to match the printer port, i.e.
-.I p9100d, p9101d
-and
-.IR p9102d .
-.LP
-When running under inetd, the
-.I /etc/inetd.conf
-entry should look something like this (with tcpwrappers protection):
-.sp
-.nf
-p9101 stream tcp nowait root /usr/sbin/tcpd /sbin/p910nd
-.fi
-.sp
-Don't forget to add an entry in
-.I /etc/services
-for the corresponding port.
-.LP
-If operating with lprng, use the host%port syntax for the
-printer device to send jobs to it.
-.LP
-If operating with CUPS, this is supported as the AppSocket
-protocol, also known as the JetDirect (probably TM) protocol.
-.LP
-If operating with classic Berkeley lpd, a sample client,
-.IR client.pl ,
-is provided.
-This should be installed as the ifilter (if=) in /etc/printcap.
-.I banner.pl
-should be installed as the ofilter (of=) in /etc/printcap.
-It may be necessary to create a dummy spool file for lpd (lp=).
-This file will be opened but not written to.
-The corresponding C versions are left as an exercise for the reader.
-.LP
-When running under inetd, more than one instance could be started.
-To avoid problems with multiple instances attempting to access the
-printer at the same time, make sure that only one client is active
-at any one time. This can be done by designating one host as the
-spooler and sending all jobs to this host. You will probably
-need to set up an intermediate queue anyway to provide print job filtering.
-.LP
-If compiled with USE_LIBWRAP and linked with -lwrap, it uses the libwrap
-library (tcpwrappers). Access control can be done with /etc/hosts.allow
-and /etc/hosts.deny. The service name is p910nd.
-.SH DIAGNOSTICS
-.I p910nd
-logs error messages to syslog.
-.SH "SEE ALSO"
-printcap(5), hosts_access(5)
-.SH FILES
-/var/run/p9100d.pid, /var/lock/subsys/p9100d, /etc/hosts.allow, /etc/hosts.deny

- *	Port 9100+n daemon
- *	Accepts a connection from port 9100+n and copy stream to
- *	/dev/lpn, where n = 0,1,2.
- *
- *	Run standalone as: p910nd [0|1|2]
- *
- *	Run under inetd as:
- *	p910n stream tcp nowait root /usr/sbin/tcpd p910nd [0|1|2]
- *	 where p910n is an /etc/services entry for
- *	 port 9100, 9101 or 9102 as the case may be.
- *	 root can be replaced by any uid with rw permission on /dev/lpn
- *
- *	Port 9100+n will then be passively opened
- *	n defaults to 0
- *
- *	Version 0.8
- *	Allow specifying address to bind to
- *
- *	Version 0.7
- *	Bidirectional data transfer
- *
- *	Version 0.6
- *	Arne Bernin fixed some cast warnings, corrected the version number
- *	and added a -v option to print the version.
- *
- *	Version 0.5
- *	-DUSE_LIBWRAP and -lwrap enables hosts_access (tcpwrappers) checking.
- *
- *	Version 0.4
- *	Ken Yap (ken_yap@users.sourceforge.net), April 2001
- *	Placed under GPL.
- *
- *	Added -f switch to specify device which overrides /dev/lpn.
- *	But number is still required get distinct ports and locks.
- *
- *	Added locking so that two invocations of the daemon under inetd
- *	don't try to open the printer at the same time. This can happen
- *	even if there is one host running clients because the previous
- *	client can exit after it has sent all data but the printer has not
- *	finished printing and inetd starts up a new daemon when the next
- *	request comes in too soon.
- *
- *	Various things could be Linux specific. I don't
- *	think there is much demand for this program outside of PCs,
- *	but if you port it to other distributions or platforms,
- *	I'd be happy to receive your patches.

-.TH PPMTOANSI 1 "January 12, 1997"
-.SH NAME
-ppmtoansi \- Graphics Conversion Program For Extended ANSI Escape Codes
-.SH SYNOPSIS
-.B ppmtoansi
-[
-.SM \-b
-r/g/b ] [
-.SM \-t
-r/g/b:idx] [
-.SM \-x
-<xoffset> ] [
-.SM \-y
-<yoffset> ] [
-<filename> ]
-.SH DESCRIPTION
-.I ppmtoansi
-converts input files in
-.IR ppm (5)
-format to escape sequences that are understood by
-.IR etherboot .
-This allows for displaying icons and logos on the BOOT-Prom's splash
-screen.
-.PP
-If no input file is specified, data is read from
-.IR standard
-.IR input .
-All output is send to 
-.IR standard
-.IR output ,
-error messages go to
-.IR standard
-.IR error .
-.I ppmtoansi
-tries to do some compression and minimizes the output filesize.
-.SH OPTIONS
-.TP
-.B \-b
-Specifies the
-.IR red ,
-.IR green , and
-.IR blue
-intensities for the background color. This information is
-used for providing a shape mask. All values are in the range from 0 to
-255.
-.TP
-.B \-t
-Allows for explicitly providing a translation between color values and
-color indices. The indices are in the range 0 to 7 and conform to the
-standard
-.IR ANSI
-.IR colorcodes .
-.RS
-.PP
-0 black       4 blue
-.PP
-1 red         5 magenta
-.PP
-2 green       6 cyan
-.PP
-3 yellow      7 white
-.PP
-If no translations apply,
-.IR ppmtoansi
-will automatically select the color that is closest.
-.RE
-.TP
-.B \-x
-Specify an X offset relative to the current text cursor position.
-.TP
-.B \-y
-Specify an Y offset relative to the current text cursor position.
-.SH FILE FORMAT
-.IR ppmtoansi
-uses these extensions to the standard
-.B ANSI escape
-.BR codes .
-.TP
-.B <esc>[a;b;c;d+<data>
-Draw pixel data.  Use one byte per pixel.  Colors are encoded as shown
-above.  In text mode, graphics is approximated by outputting suitable
-characters.  Parameters differ depending on the number of parameters
-passed:
-.RS
-.TP
-.B cnt
-.IR cnt
-data bytes follow. They will be drawn to the right of the last
-graphics position.
-.TP
-.B rle;col
-The next
-.IR rle
-pixels have the value
-.IR col .
-They will be drawn to the right of the last graphics position. No data
-bytes follow.
-.TP
-.B x;y;cnt
-.IR cnt
-data bytes follow. They will be drawn relative to the top left corner
-of the text cursor with an offset of
-.RI ( x / y ).
-.TP
-.B x;y;rle;col
-the next
-.IR rle
-pixels have the value
-.IR col .
-They will be drawn relative to the top left corner of the text cursor
-with an offset of
-.RI ( x / y ).
-No data bytes follow.
-.RE
-.TP
-.B <esc>[a;b;c;d\-<data>
-same as above, but pack pixels into three bits. The first pixel is
-stored in the three most significant bits of the first data byte.
-.SH "SEE ALSO"
-ppm(5), mknbi-linux(8), mknbi-dos(8).

-This code was written by Dave Ashley for NXTV, Inc. It is released under
-the terms of the GPL. The purpose is to let you write to the bootrom of
-the SMC9462TX card. The assumption is that you've stuck an AT29C512 in the
-socket. Note that the board has pins D5 + D6 reversed on the socket. Also
-the socket only supplies 3.3V to the rom. Good luck trying to locate a
-DIP programmable flash device that operates at 3.3V. What I do is to bend
-pin 32 back and solder a wire directly from the 5V side of the 3.3V regulator
-over to it. The dp83820's bootrom interface pins are all 5V logic tolerant.
-However mod your board at your own risk, no warranty or guarantees are implied
-or given!!! If you don't wire the 5V to the AT29C512, you can still read
-the rom contents (it operates ok at 3.3V evidently) but you can't write to it
-because the AT29C512 has a safety protection, it disables writes if the
-power supply voltage drops below 3.8V.
-
-See the comments at the top of the 2 C files for more information.
-
-The Makefile needs to be hacked to build for your system. If you can't
-figure it out you shouldn't be messing with this stuff anyway.

-   Kernel module for the dp83820 flash write utility. This code was written
-   by Dave Ashley for NXTV, Inc.
-   Copyright 2004 by NXTV, Inc.
-   Written 20040219 by Dave Ashley.
-
-   This code is released under the terms of the GPL. No warranty.
-
-   THEORY: The dp83820 bootrom interface is flawed in that you can't
-   read or write a single byte at a time, and this is required in order
-   to write to flash devices like the AT29C512. So the workaround is
-   to use the chips ability to map into memory the bootrom, then the cpu
-   can directly do byte accesses.
-
-   The problem is that a "feature" of the dp83820 is that when you map
-   in the bootrom, you conveniently lose access to the PCI registers.
-   So we need to do this in kernel space and wrap every access to the
-   bootrom within interrupt_disable/restore, in case a network interrupt
-   were to come in.
-
-   This kernel module is very simple, it just creates a proc file
-   /proc/dp83820
-   If you write 3 bytes to this file you are doing a write to the flashrom:
-
-Byte 1   2    3
-   ALOW AHIGH DATA
-
-   If you write 2 bytes to this file you are doing a read from the flashrom:
-Byte 1   2
-   ALOW AHIGH
-   Then the next read from the file will return a single byte of what
-   was at that location.
-
-   You only get one shot at accessing the proc file, you need to then
-   close/open if you want to do another access. This could probably be
-   cleaned up pretty easily so more accesses can be done without having
-   to close/open the file.

-This is a TFTP to HTTP proxy. To the TFTP client it looks like a TFTP
-server. To the HTTP server it looks like a HTTP client. So you can store
-your boot files on the HTTP server. Or even create them with a CGI
-program. E.g. if you can get dhcpd to send a filename which has strings
-representing attributes of the client, as determined from the DHCP
-request, then you can get the CGI program to parse this and send the
-appropriate image, which might even be synthesised.
-
-There are two versions of the proxy, in Perl and in Java.
-
-1. The Perl version.
-
-This is the original quick Perl hack conceived in a moment of madness.
-:-) Perl is great for prototyping.
-
-To run it, you need Perl 5.8.0 or later and all the Perl modules listed
-at the top of the program installed. Edit and install the xinetd config
-file as /etc/xinetd.d/t2hproxy and restart xinetd. The prefix is the
-string that is prepended to all filenames to form the URL requested from
-the HTTP server. Remember you need the trailing / if the filenames don't
-start with /.
-
-This is only a proof-of concept. It has these drawbacks at the moment:
-
-+ (I don't consider this a draback, but some may.) It's started from
-xinetd because xinetd handles all the socket listening, IP address
-checking, rate limiting, etc.
-
-+ It has no cache. Use a proxy to do the caching (there's a --proxy
-option). This also takes care of fetching from outside a firewall.
-
-+ It reads the entire HTTP content into memory before serving. Ideally
-it should stream it from the HTTP server to minimise memory usage. This
-is a serious drawback for booting lots of clients. Each instance of the
-server will consume an amount of memory equal to the size of image
-loaded.
-
-+ If the HTTP server is at the end of a slow link there is a delay
-before the first data block is sent.  The client may timeout before
-then.  Another reason for streaming, as this allows the first block to
-be sent sooner.  A local cache primed with the images in advance may
-help. Using the blocksize option helps here because this causes the
-server to send the OACK to the client immediately before the data is
-fetched and this prevents it from starting up another connection.
-
-+ The transfer size may not be obtainable from the HTTP headers in all
-cases, e.g. a CGI constructed image. This matters for clients that need
-the tsize extension, which is not supported at the moment.
-
-If I'm feeling masochistic I may write a Java version, which should take
-care of the multi-threading and streaming.
-
-2. The Java version
-
-The main problem with the Perl version is that it does not stream the
-HTTP input but sucks it all in at once. As mentioned, this causes a
-delay as well as requiring memory to hold the image. I could fix this by
-doing the polling on the HTTP socket myself instead of letting LWP do
-it, but that's for later. Java has streaming facilities as well as
-threading and is also somewhat portable.  So I decided to be masochistic
-and give it a go.  But boy is Java bureaucratic.
-
-You will need a Java 1.4 JRE, because I use the java.nio classes; and
-the commons-httpclient and commons-logging jars from the
-jakarta.apache.org project. As I understand it, there are several ways
-to get those jars on your classpath. One is to put it in the directory
-where your java extensions jars are kept, normally
-$JAVA_HOME/jre/lib/ext. But it may not be writable to you. Another is to
-set your $CLASSPATH variable to have those jars in the path. A third is
-to use the -cp option of the java interpreter, see the shell script
-runT2hproxy for details.
-
-All the source is in one Java file. build.xml is a "Makefile" for ant to
-compile and jar it. You should then edit runT2proxy.sh as required, then
-start it. As with the Perl version, the prefix is what's prepended to
-the filenames requested by the TFTP client, and the proxy is the
-host:port string for the proxy if you are using one. On *ix you will
-need root permission to listen on ports below 1024 (TFTP is at 69 UDP by
-default).
-
-Currently it logs to stderr, but you can change this by downloading and
-installing the log4j jar from jakarta.apache.org and instructing
-commons-logging to use that, with a command line property setting and a
-property file.  Destinations could be syslog, or a file, or an event
-logger, or...; it's supposedly very flexible.
-
-3. Licensing
-
-All this code is GPLed. For details read the file COPYING found in the
-Etherboot top directory since it currently bundled with Etherboot. I
-don't see the point of including COPYING in every directory.

-.TH TFTP 1 "September 20, 1988"
-.UC 6
-.SH NAME
-tftp \- trivial file transfer program
-.SH SYNOPSIS
-.B tftp
-[
-host
-]
-.SH DESCRIPTION
-.I Tftp
-is the user interface to the Internet TFTP
-(Trivial File Transfer Protocol),
-which allows users to transfer files to and from a remote machine.
-The remote
-.I host
-may be specified on the command line, in which case
-.I tftp
-uses
-.I host
-as the default host for future transfers (see the
-.B connect
-command below).
-.SH COMMANDS
-Once
-.I tftp
-is running, it issues the prompt
-.B tftp>
-and recognizes the following commands:
-.TP
-\fBconnect\fP \fIhost-name\fP [ \fIport\fP ]
-Set the
-.I host
-(and optionally
-.IR port )
-for transfers.
-Note that the TFTP protocol, unlike the FTP protocol,
-does not maintain connections betweeen transfers; thus, the
-.I connect
-command does not actually create a connection,
-but merely remembers what host is to be used for transfers.
-You do not have to use the 
-.I connect
-command; the remote host can be specified as part of the
-.I get
-or
-.I put
-commands.
-.TP
-\fBmode\fP \fItransfer-mode\fP
-Set the mode for transfers; 
-.I transfer-mode
-may be one of
-.IR ascii
-or
-.IR binary .
-The default is
-.IR ascii .
-.TP
-\fBput\fP \fIfile\fP
-.ns
-.TP
-\fBput\fP \fIlocalfile remotefile\fP
-.ns
-.TP
-\fBput\fP \fIfile1 file2 ... fileN remote-directory\fP
-Put a file or set of files to the specified
-remote file or directory.
-The destination
-can be in one of two forms:
-a filename on the remote host, if the host has already been specified,
-or a string of the form
-.I host:filename
-to specify both a host and filename at the same time.
-If the latter form is used,
-the hostname specified becomes the default for future transfers.
-If the remote-directory form is used, the remote host is
-assumed to be a
-.I UNIX
-machine.
-.TP
-\fBget\fP \fIfilename\fP
-.ns
-.TP
-\fBget\fP \fIremotename\fP \fIlocalname\fP
-.ns
-.TP
-\fBget\fP \fIfile1\fP \fIfile2\fP ... \fIfileN\fP
-Get a file or set of files from the specified
-.IR sources .
-.I Source
-can be in one of two forms:
-a filename on the remote host, if the host has already been specified,
-or a string of the form
-.I host:filename
-to specify both a host and filename at the same time.
-If the latter form is used,
-the last hostname specified becomes the default for future transfers.
-.TP
-.B quit
-Exit
-.IR tftp .
-An end of file also exits.
-.TP
-.B verbose
-Toggle verbose mode.
-.TP
-.B trace
-Toggle packet tracing.
-.TP
-.B status
-Show current status.
-.TP
-\fBrexmt\fP \fIretransmission-timeout\fP
-Set the per-packet retransmission timeout, in seconds.
-.TP
-\fBtimeout\fP \fItotal-transmission-timeout\fP
-Set the total transmission timeout, in seconds.
-.TP
-.B ascii
-Shorthand for "mode ascii"
-.TP
-.B binary
-Shorthand for "mode binary"
-.TP
-\fBblocksize\fP \fItransfer-blocksize\fP
-Set the blocksize that is used for transfers. This assumes that the
-server knows about RFC1782 and RFC1783 extensions to the TFTP
-protocol; automatic fallback is supported and will result in a default
-blocksize of 512 octets.
-.TP
-\fB?\fP \ [ \fIcommand-name\fP ... ]
-Print help information.
-.SH BUGS
-.PP
-Because there is no user-login or validation within
-the
-.I TFTP
-protocol, the remote site will probably have some
-sort of file-access restrictions in place.  The
-exact methods are specific to each site and therefore
-difficult to document here.

-.SH NAME
-tftpd \- DARPA Trivial File Transfer Protocol server
-.SH SYNOPSIS
-.B /etc/tftpd
-[
-.SM \-c
-<rootdir> ] [
-.SM \-d
-] [
-.SM \-r
-<filter> ]
-.SH DESCRIPTION
-.I Tftpd
-is a server which supports the DARPA Trivial File Transfer
-Protocol.
-The TFTP server operates
-at the port indicated in the ``tftp'' service description;
-see
-.IR services (5).
-The server is normally started by
-.IR inetd (8).
-.PP
-The use of
-.I tftp
-does not require an account or password on the remote system.
-Due to the lack of authentication information, 
-.I tftpd
-will allow only publicly readable files to be
-accessed.
-Files may be written only if they already exist and are publicly writable.
-Note that this extends the concept of ``public'' to include
-all users on all hosts that can be reached through the network;
-this may not be appropriate on all systems, and its implications
-should be considered before enabling tftp service.
-The server should have the user ID with the lowest possible privilege.
-.SH OPTIONS
-.TP
-.B \-c
-Pathname of a directory that is considered the rootdirectory for all
-transfers. N.B.
-.I tftpd
-does not actually perform a
-.IR chroot (2)
-call; you should be aware of the security implications and you
-probably should run the server from an unpriviledged account.
-.TP
-.B \-d
-Increased debugging level.
-.TP
-.B \-r
-Pathname of a file that is considered to be a filter program. Whenever
-a client tries to download this file, the filter will be started and
-its output is send to the client. An arbitrary amount of these
-filters can be specified.
-.SH "SEE ALSO"
-tftp(1), inetd(8)

-Notes on turning tomsrtbt El Torito into a Etherboot image:
-
-0. Tomsrtbt (http://www.toms.net/) is an all-purpose rescue and utility
-1-floppy Linux system. You can read all about it at the web site. These
-notes explain how to turn the El Torito version of it into a netbootable
-image for Etherboot.  Note that the .img file is not an ISO image, it is
-a 2.88M floppy emulation image for writing onto a CD-R(W) with mkisofs.
-It's actually a minix filesystem.  Inside it are the kernel bz2bzImage
-and initrd.bz2.
-
-1. First uncompress the .img:
-
-	bunzip2 tomsrtbt-2.0.103.ElTorito.288.img.bz2
-
-2. Mount the image using loopback. You probably need to be root to do
-this:
-
-	mount -o ro,loop tomsrtbt-2.0.103.ElTorito.288.img /media/floppy
-
-I've specified /media/floppy which is the floppy mount point for my
-system, but any convenient directory will do.
-
-3. Copy the kernel image and initrd off it:
-
-	cp -p /media/floppy/bz2bzImage /media/floppy/initrd.bz2 .
-
-4. Use mkelf-linux (or mknbi-linux) to make a netbootable image:
-
-mkelf-linux --append='root=100' bz2bzImage initrd.bz2 > tomsrtbt.nb
-
-root=100 means use /dev/ram0 (device 1,0) as the root device.
-
-5. That's it. Clean up by unmounting the .img:
-
-	umount /media/cdrom
-
-tomsrtbt.nb can now be loaded with Etherboot. Have fun.

-Subject: [Etherboot-developers] WOL Routine
-
-Attached is a WOL routine that can be used to wake a remote server from 
-gpxe.  I put wol.c in src/usr and wol.h in src/include/usr.  This is really 
-in improved replacement of that in contrib\wakeonlan\wakeserver.patch.  This 
-version will no longer work since the eth_transmit routine no longer works 
-with the newer driver arhitecture such as the e1000 driver.
-
-Please consider adding it to gpxe preferrably in the main src directory or 
-in the contrib directory.
-
-Thank you
