The (classic legacy) BIOS is dead. Long live the BIOS. (Miscellaneous)

A new PC with Windows 8 Compatibility requires that "Such a system may also support fallback to
legacy BIOS boot on systems with OS which do not support UEFI ..."

Here reference is made to legacy BIOS option ROM and the UEFI Compatibility Support Module.

Yes it's unavoidable. I already talked about it here. For some years there will be hardware with compatability module in UEFI but it will be dropped. The alternative is more support for coreboot + seabios project.
