Does anyone know where I can get the information of video card rom hacking for OF based systems? I don't mean simply flashing a card, but the actual code required for a rom to make it compatible with OpenFirmware based systems. I read that some Mac OF based cards work in Sun SPARC based computers as well. I could just compare a pc and a g5 1900xt bios to see whats different, but I want to experiment, see if I can't take say an 8600 and make it OpenFirmware capable. All links, notes, mailing lists, and what have you of information is welcome.
