My previous attemps to put coreboot on my laptop (Asus G1, with vgarom on bios) have failed. I want to keep trying to get something to work but it is a real pain in the behind to keep taking out the flash chip and reprogramming it. I think it could be easier to have coreboot booting the original bios , and run any other payload on some key press (or something like that). That way, i could keep flashing new code to try, and in case it doesnt work just boot the orig. bios and reflash. (this is asuming coreboot gets to run)
Is it possible ?
Short answer: No, this is not possible.
Long answer: Yes, something like this is possible, but you will have to modify the original BIOS and coreboot and rewrite parts of them. Since you have no sources for the original BIOS, this will be pretty difficult. Basically, neither coreboot nor the original BIOS expect to have a switcher run before them. That switcher would have to preserve the environment completely and not violate any coreboot/BIOS expectations. I wouldn't even try to do it without a bootle of aspirin and sources for the BIOS. If you decide to try it, good luck!
