"One of the last vestiges of closed source proprietary software
in current PCs is the PC BIOS. The BIOS, most always written in

the ROM of current motherboards--completely removing the legacy
BIOS. While the LinuxBIOS effort fully supports Linux, other modern
operating systems, e.g. *BSD, and Windows 2000/XP, could not be
directly supported because of their reliance on a few services
provided by those legacy BIOSes. In this paper, we describe how we
