Alright. What I'm trying to do here is demonstrate a known working state and use-case of coreboot. Once I have that working I want to start looking at getting it working on my hardware. Is there a better known-working state of coreboot I can use? I'd prefer to stick with qemu for this part. -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
