What's Coreboot?

coreboot is an alternate firmware image for PC BIOS. It is tiny and only loads a "payload", usually a linux kernel or SEABIOS or such. http://www.coreboot.org/Welcome_to_coreboot

Why coreboot?

Because EFI. We can't grant or adopt hardware that contains locked non-free firmware. Regular BIOS are bad enough!
