tiara borrowed lots of grub code, not quite the same thing. But it could be a place to start for actual grub support. Other things to look at: ppcboot http://ppcboot.sourceforge.net/ armboot http://sourceforge.net/projects/armboot gbios http://www.humboldt.co.uk/gbios.html These are related non-x86 projects that I have found. > you know more than me.

The PCBIOS interrupt table most be at physical address 0. Among other things video cards implement int 0x10. And to so they set the int 0x10 vector by writing to the interrupt table. This is the big reason I wanted it in it's own ELF utitlity. The PCBIOS memory layout is different from the optimal/convinient LinuxBIOS layout. If we take this route we can copy the LinuxBIOS table to 0xF0000 and be saner. Eric
