Makefile: Use -Ox option to NASM

2012-03-26T21:59:39+00:00

We already require a new enough version of NASM that the -Ox option is
supported, so just use it.

Makefile: Move Makefile fragments into mk/

2011-04-07T16:59:11+00:00

Move the MCONFIG files into a mk/ directory and give them more
descriptive names.

This is purely a cosmetic change to make the 'include' directives a
bit more coherent by making it obvious exactly which MCONFIG file
we're including. For example, in com32/lua/src/Makefile we exchange
the line,

	include ../../MCONFIG

for the much more comprehensible,

	include $(MAKEDIR)/com32.mk

Merge syslinux/extlinux patch code and core code

2010-06-21T00:07:52+00:00

Merge the SYSLINUX and EXTLINUX patching code and core code, removing
EXTLINUX as a separate derivative.  All the disk-based systems now use
the same code.

mdiskchk: Add --no-sequential mode

2010-06-15T04:48:56+00:00

It might be useful to suppress MDISKCHK.COM's classic behaviour
of probing all BIOS drive numbers in search of MEMDISKs.  Some BIOSes
might not enjoy being probed.

eltorito: Include drive 0xFF in scan

2010-06-15T04:48:34+00:00

Although drive 0xFF could yield a false positive as the El Torito
booted-from drive number, some users of GRUB4DOS actually use
this drive number, so we should include it in our scan.

eltorito: Scan upwards instead of downwards

2010-06-17T18:44:37+00:00

A developer for GRUB4DOS called tinybit has reported that some
BIOSes crash when the DOS ElTorito.Sys driver scans drive number
0xFF.  According to the El Torito specification, drive 0x7F
means "terminate all," so a plausible explanation suggested
by H. Peter Anvin is that the drive 0xFF is a shadow of drive
0x7F, thus contributing to a failure on these BIOSes.

Now we scan from 0x80 through 0xFF, instead.

mdiskchk: Support three new features

2010-06-11T05:08:41+00:00

MDISKCHK.COM now supports three new modes:

mdiskchk.com --mbfts
  This mode will scan between free base memory and
  0xA00000 looking for MEMDISK mBFTs.  For each one
  found, its detail will be reported.

mdiskchk.com --safe-hooks
  This mode will attempt to walk the chain of INT 13h
  "safe hooks".  For each MEMDISK "safe hook" found,
  its detail will be reported.

mdiskchk.com --batch-output
  This mode suppresses the normal detail report and
  instead outputs a list of DOS SET commands.  This
  is useful if one wishes to populate a batch file
  and call that batch file to set DOS environment
  variables, so that programs have access to those
  MEMDISK kernel arguments passed at boot-time.

These command-line options may be combined.

For example, your AUTOEXEC.BAT might go:
  @echo off
  echo @echo off>setenv.bat
  mdiskchk.com -m -s -b>>setenv.bat
  call setenv.bat>nul

dosutil: move copybs here, update Makefile

2010-02-15T23:20:56+00:00

Move copybs to dosutil, change the Makefile to deal with UPX being
able to compress (e.g. very small files.)

dosutil: don't remove targets which need Watcom even for "make spotless"

2009-12-31T00:03:22+00:00

Most systems won't have Watcom installed, so don't remove
Watcom-generated binaries even with "make spotless".
