OK now it should work, but I'm getting this now in gdb when I'm trying to load the file:

(gdb) file /home/sphinx/coreboot/coreboot-v2/targets/emulation/qemu-x86/qemu-x86/coreboot.rom
"/home/sphinx/coreboot/coreboot-v2/targets/emulation/qemu-x86/qemu-x86/coreboot.rom": not in executable format: File format not recognized

Argh! My fault... It belongs into Options.lb, not Config.lb. I corrected the Wiki page.

You need to put the "uses" in the top half of the file (to the other uses statements) and the "default" into the lower half (where the other default statements are)

How does it fail? Please paste the last few lines of the log so we can
investigate.

With more info, we can probably figure it out.
