There is an interesting article on the AMD blog site about plans they have to implement “coreboot” for some new chipsets/processors: An Update on coreboot | Business Blog
According to coreboot.org: coreboot and Benefits - coreboot Coreboot (formerly known as LinuxBIOS) is a Free Software project aimed at replacing the proprietary BIOS (firmware) in computers with a GNU/Linu based version. Presumeably being 100% free software (GPL) it has no royalties nor license fees, and because of its structure supports fast boot times.
I’m also hoping it will improve GNU/Linux distribution compatibility with motherboards in such Coreboot BIOS fitted PCs, but likely the jury is still out on that.
