Thank you very much! I got very clear concepts on coreboot, old bios and linux from you, it's very helpful. I think coreboot is doing the right thing, providing more and better support for AMD shall be a pressure on intel and other cpu and chipset vendors, I think. I'm reading the source code of flashrom now, hope i can figure out it. :)
