I am not interested.

You will certainly not come anywhere near GRUB stage 1.5 without some
number of real mode BIOS interrupts.

If you don't use any GRUB code but only FILO code you can certainly
try to find GRUB's menu.lst by emulating what GRUB stage 1 does, but
because device names are assigned differently in BIOS (which is the
abstraction used by GRUB) and FILO, the file is useless unless it is
adjusted for FILO's device names. (Then it becomes useless for GRUB
of course.)

This is pointless. But let's talk that new boot spec.
