Thanks for that paper, might prove to be an interesting piece to read. > how long will be be before BIOS function support is totally gone? I > don't know. I don't know either. Current situation seems to be system with 1 of the following: * traditional BIOS * traditional BIOS with some tricks for allowing 3GB discs * UEFI with legacy compatibility * UEFI without legacy compatibility (Apple machines?) * Coreboot * Coreboot with SeaBIOS , allowing DOS, Windows and the usual stuff to run. If you've tested programs in QEMU..well SeaBIOS is the opensource BIOS they're using there. On physical machines it's used on top of Coreboot (for those boards ported/supported, that is). > UEFI is taking over and slowly(?)/fastly(?) transitioning out BIOS > functionality.

If I understand correctly, GPT partitioning scheme isn't a requirement for UEFI, but UEFI is a requirement for GPT partitioning scheme (used on discs with more than 2GB capacity). So far it seems like current UEFI implementations have a legacy compatibility layer. I share your concerns about future versions dropping that, ofcourse. However above mentioned SeaBIOS should work, provided your board gets supported by CoreBoot. I don't think it's possible to hook up SeaBIOS to UEFI. Another option ofcourse is if motherboards start embedding their own hypervisor for para-virtualisation. I don't see BIOS disappearing from virtual machines any time soon. > hey - I am a forward thinker. I see problems down the road and I like to > solve them up front.
