coreboot is an open source (GPLv2) x86 lightweight firmware written in C
(with optional BIOS and EFI compatibility modules if anyone cares).
While it does not support all current x86 chipsets, it still does
support quite a few mainboards.
The developers are friendly and try to fix any reported bugs. There are
two big obstacles until x86 world domination, though: A dozen core
developers are simply not enough for the huge task (there are more open
specs than developers can keep up with), and some chipset vendors don't
open their specs. Anyone interested is invited to contribute and make
the world a better place.

Oh, and it supports packing a Linux kernel in the mainboard flash ROM
for diskless/networkless booting (that coreboot+Linux combination was
called LinuxBIOS some time ago).
