Hi,
I documented the latest developments (git and crossgcc) at http://www.coreboot.org/Build_HOWTO. Please someone double-check.
My build succeeded following these instructions. As a first-time user, it would be helpful to have a quick-start guide which would be basically this wiki page + the steps necessary to do boot what I built in qemu. There are bits of that here:
Unfortunately, it looks like that page has old information on it.
Which version of Qemu was that again?
$ qemu --version QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008 Fabrice Bellard
Is it integrated into the payload? Reading the QEMU_Build_tutorial, http://www.coreboot.org/QEMU_Build_Tutorial, led me to try:
$ qemu -bios build/coreboot.rom -hda /dev/zero -serial stdio
This resulted in something else entirely, the shell output terminating in the following:

You're now running coreboot, but coreboot was unable to find your payload (eg, SeaBIOS).
However, it seems the CBFS header is corrupted, so it is not even checking for a payload file.
Not sure why, on first sight.
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.
