Hi,

	as tested with Sascha

	you can run it from qemu (more easy to debug)

	first you will need an EFI binary
	you can use this one
	http://ufpr.dl.sourceforge.net/project/edk2/OVMF/OVMF-X64-r15214.zip

	and then you need to create a vfat FS

	dd if=/dev/zero bs=1M count=10 > dosfs; mkfs.vfat dosfs

	in the dosfs mounted copy the barebox.efi in /EFI/BOOT/ as BOOTx64.efi

	and finally the magic

	qemu-system-x86_64 -pflash OVMF.fd -nographic dosfs

Best Regards,
J.
