Public Service Announcement: The LinuxBIOS project, a Free Software project which intends to replace the proprietary BIOS found in most computers these days, has been renamed to coreboot.
The old name has become quite a misnomer in recent years; the name LinuxBIOS created the impression that it's a drop-in BIOS-replacement and that it's using Linux or is Linux-specific in any way. Neither is the case.
- coreboot is not a BIOS in the sense that it provides the legacy BIOS callbacks / interrupt routines. Instead, coreboot is just a small hardware initialization firmware. It does some basic hardware init, then hands over control to one of many possible payloads. This can be a boot loader such as FILO (or GRUB2, which shall ultimately replace FILO) if you want to boot from disk, or Plan 9, or memtest86, or a Linux kernel, or OpenBIOS/OpenFirmware/SmartFirmware, or...
- coreboot is not Linux or Linux-specific. Yes, it can indeed use Linux kernels as payload (i.e., you put the Linux kernel in your flash ROM chip together with coreboot) or boot a Linux kernel indirectly using FILO/GRUB2. But as mentioned above it can also be used (together with the fitting payload) to boot other OSes or systems such as Plan 9, Windows, FreeBSD, and others.
The initial author and project leader of LinuxBIOS/coreboot, Ron Minnich, explains in more detail why the renaming was done in his original announcement on the coreboot mailing list.
