I'm running my Laptop with Barebox on EFI, so it's certainly possible. Without any error messages I can only guess what the problem might be. Have you enabled CONFIG_EFI_STUB in your kernel config? This is necessary for barebox to boot your kernel. > 2. Non-EFI - I have compiled barebox with the attached config file, but it > seems to triple fault according to qemu.

Don't use it unless you're interested in barebox development and want to fix it :-).
