whichsys.c32: execute specific command, based on Syslinux bootloader variant

2010-07-05T21:52:39+00:00

Detemine which command to execute, based on the Syslinux bootloader variant
from which you run it.

  Usage:    whichsys.c32 [-iso- command] [-pxe- command] [-sys- command]
  Examples: whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap
            whichsys.c32 -iso- config iso.cfg -sys- sys.cfg -pxe- pxe.cfg

chain.c32: add grubcfg= for passing an alternative config filename to GRUB Legacy and cleanup the root partition passing

2010-07-04T18:35:15+00:00

GRUB Legacy reserves 89 bytes for storing the filename of the configfile
from memory address 0x8217 to 0x826f.
We allow overwriting the default value (/boot/grub/menu.lst) when
grubcfg= is used together with grub=.

Examples:
  chain.c32 fs grub=/boot/grub/stage2 grubcfg=/boot/grub/grub.lst
  chain.c32 hd1,10 grub=/boot/grub/stage2 grubcfg=/boot/grub/grub.lst

Use a structure instead of hard-coded offsets for modifying the install_partition variable
(and the configfile name) in the stage2 file.

Add some comments about the "boot information format" of the Multiboot specification, which
is very similar to the install_partition variable used by GRUB Legacy.

ifplop.c32: Detect if PLoP USB/CD INT13h hook is enabled/disabled

2010-07-01T20:39:34+00:00

New module which detects if the PLoP Boot Loader already has booted a
CDROM or USB drive by checking for the presence of the PLoP INT13h hook.

The following assembly code (NASM) can detect the PLoP INT13h hook:

  mov eax,'PoLP'  ; Reverse of 'PLoP'
  mov ebp,'DKHC'  ; Reverse of 'CHKD'
  int 13h
  cmp eax,' sey'  ; Reverse of 'yes '
  jz plop_INT13h_active
