Hello,
Sorry for not replying earlier, I'm currently busy trying to figure out how to
access the Compatibility Support Module, and possibly enable lecagy boot.

Well, this should also work if grub is the main bootloader of your machine,
but I think it would be a bit harder in the case you have grub on a EFI
bootable CD or USB stick (or that would depend on the primary bootloader in
this case). But actually, I don't know this part very well ...
I also still have to clean the chainloader options patch, but here is the
changelog for the others:
2007-11-18 Alexandre Boeglin <[EMAIL PROTECTED]>
* normal/arg.c (grub_arg_parse): If one of the args is "--", add remaining
N args, instead of "--" N times.
* commands/i386/efi/halt.c: New file.
* commands/i386/efi/reboot.c: New file.
* conf/i386-efi.rmk (grub_emu_SOURCES): Replace i386/pc/halt.c and reboot.c by
i386/efi/halt.c and reboot.c.
(grub_install_SOURCES): Add halt.mod and reboot.mod.
(halt_mod_SOURCES): New variable.
(halt_mod_CFLAGS): Likewise.
(halt_mod_LDFLAGS): Likewise.
(reboot_mod_SOURCES): Likewise.
(reboot_mod_CFLAGS): Likewise.
(reboot_mod_LDFLAGS): Likewise.
* include/grub/efi/efi.h (grub_reboot): New function declaration.
(grub_halt): Likewise.
* kern/efi/efi.c (grub_reboot): New function.
(grub_halt): Likewise.
And I just received the copyright assignment papers yesterday. I will post
them on monday.
Regards,
Alex
