Changes in 1.46:
* New program PXELINUX to do network booting over the PXE
(Pre-Execution Environment) network booting protocol. See
pxelinux.doc for details.
Changes in 1.45:
* Serial console support. See syslinux.doc for details.
Changes in 1.44:
* Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the
kernel stepping on it; 3f000000h was apparently a higher
limit than the kernel used!
Changes in 1.43:
* Add sys2ansi.pl script to display the contents of a
colorized SYSLINUX file.
* Changed the io_delay once again, after a report that the
old delay port causes hangs on some systems.
Changes in 1.42:
* Frob the "fast A20 gate" port as well as the keyboard
controller; will this help systems with problems?
* Be even more paranoid about A20, unfortunately even this
seems to be not paranoid enough... what I don't understand
is that if there is hardware out there *this broken*, how
can it run Linux at all? Report an error message rather
than hang forever if A20 is stuck.
* Include some intermediate files in the distribution, plus
provide a "make installer" target for distributors to relink
the install programs only. I would prefer the syslinux boot
loader proper to be "binary clean" for debuggablity -- use
"make clean ; make installer" to rebuild the installers only.
Changes in 1.41:
* Don't get confused by directories, volume labels, or VFAT
long names.
* Use INT 15h, AX=0E801h to query memory size before trying
INT 15h, AH=88h. This not only provides more headroom
between the kernel and the initrd on large-memory machines,
but it appears some recent BIOSes actually have started
returning garbage for the AH=88h (older) call.
* Trust high memory beyond the 15 MB mark if the user has
specified it, or if obtained with INT 15h, AH=0E801h (with
no memory holes above 1 MB.)
Changes in 1.40:
* Increase A20M delay and put in a test to avoid problems on
certain IBM Thinkpads (thanks to Donnie Barnes of RedHat
for vital info on this one.)
* Support COMBOOT style boot command images.
* Support chain loading (foreign operating systems, e.g. DOS).
* Include a new "copybs" DOS utility to copy a boot sector to
a file (under Linux, use "dd".)
* Fix the DOS installer to work for disks over 32 MB.
* SYSLINUX should now handle disks with more than 65536 tracks.
Changes in 1.37:
* Fix a bug that caused "label" statements in syslinux.cfg to
not be handled properly.
* Updated the documentation. Among other things, we now allow
up to 128 "label" statements.
Changes in 1.36:
* Fix for booting old (pre-initrd) kernels.
* It seems at least some versions of OS/2 doesn't set up all
the fields in the superblock correctly. Account for that.
* Fix bug that caused boot failure when using the mem= option.
Changes in 1.35:
* Loading from partitions now should work properly. (Actually
tested, this time. You should even be able to dd a floppy
to a partition and boot from it.)
* Removed large workaround code for an alleged ancient BIOS
bug I have never actually seen. The -s option should work
on those machines, anyway.
* Support for simple keyboard remappings, same as used by
LILO (once again to support localization.) The program
keytab-lilo.pl from the LILO distribution included to
generate such maps.
* Added a "safe, slow and stupid" (-s) option to the
installers. This option will lobotomize the boot sector to
hopefully work on even very buggy BIOSes.
Changes in 1.34:
* Ability to load a VGA font on bootup (for localized Linux
distributions.)
Changes in 1.33:
* Bug fix in the Linux installer.
* Added a workaround for a bug in certain AMI/Intel BIOSes
when booting from CD-ROM.
* Documentation changes.
Changes in 1.32:
* FAT16 filesystems are now supported.
Changes in 1.31:
* Now compiles under Linux, using NASM, rather than using
Turbo Assembler under DOS. See http://www.cryogen.com/Nasm
for information about NASM.
* Linux-hosted SYSLINUX installer, as well as a
rewritten DOS installer (now is written in assembler, so we
don't need Turbo C.)
Changes in 1.30:
* Added support for loading bzImage and initrd loading, and made
SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31).
* Added LILO-style kernel labels; see the LABEL and IMPLICIT
keywords in README file.
* Added support for colorization of intro and help screens.
* The vga= option is now handled correctly.
* Massive rewrite of large chunks of the code in order to
support the first two new features.
Changes in 1.20:
* Added simple online help at the "boot:" prompt.
* Removed 2880K image as I no longer have access to such a
floppy drive. (Donations accepted!!)
* Decided to distribute the source in a subdirectory rather
than in a nested zipfile.
Changes in 1.11:
* Removed a sanity check which would cause booting to fail on
Phoenix BIOS version 4.03. Apparently this BIOS is buggy.
Changes in 1.10:
* Added configuration file SYSLINUX.CFG. This file contains all
configurable options, and can be edited from any OS which can
access an MS-DOS filesystem; there is no longer a need to run
SYSLINUX.EXE except to write the boot sector.
* Default command line now given by "default" line in config
file.
* LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by
"display" and "prompt" lines in config file.
* LILO-style option appending now supported ("append" line in
config file).
* Prompt timeout is now supported ("timeout" line in config
file). The timeout is cancelled when anything is typed on the
command line.
* Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts
the kernel loading in progress and returns the user to the
boot: prompt.
* The installer now automatically sets the READONLY flag on
LDLINUX.SYS.
* Added 2880K disk image.
Changes in 1.03:
* Fixed bug that would prevent booting from double-density
floppies and other DOS filesystems with multiple sectors per
cluster.
* Added 720K disk image.
* Changed default kernel name on disk images to LINUX.
Changes in 1.02:
* Fixed bug that would garble the command line on recent kernels
with more than 4 sectors of setup code (this wasn't really a
*bug*; rather, a kernel change broke the code. Unfortunately
the Linux boot interface is still sorely undocumented).
* Added BOOTMSG.TXT file support (message file which does not
force display of the boot prompt).
Changes in 1.01:
* Fixed bug on some (most?) 386 BIOSes would require two boot
attempts.
