Coreboot is not the OS loader if the OS is on a CD. Coreboot is what
runs before that loader. An OS loader can be eliminated completely if
the OS fits into the boot flash, but so far this is not the typical
case. (LAB, Linux-as-Bootloader)

FILO (GRUB2?) are the OS loaders that can load from a CD. If support
for the ElTorito extension is needed it should be added there. Sorry
I wasn't more clear about this separation in the last post. I should
have been more clear since the subject says FILO but the discussion
started going toward coreboot.

But - ElTorito is needed only for floppy disk emulation. Possibly it
can be avoided completely and instead we'll have native support for
booting from the CDs that people want to use. (As FILO already does
for Linux, and hopefully will do for Windows too once booting Windows
in general works well enough.)
