We're happy to announce that we've successfully booted Windows 2000 without a legacy proprietary BIOS. We accomplished this by developing software that combined elements from two very successful projects: LinuxBIOS and BOCHS. The Etherboot project also helped in various ways. As a result, we now have a completely free software replacement for the BIOS that supports (without modification) either LILO or GRUB as bootloaders, and Linux, OpenBSD, and Windows 2000 as operating systems (NOTE: We're still working on supporting FreeBSD and Windows XP. We expect that improving ATA support will permit Win98 and WinXP to boot, and finishing PIRQ support will permit FreeBSD to boot.
