If you plan to implement this I can test it for you in real hardware.

I have known about coreboot but I do not want to mess up my bios. DUET
acts like a uefi wrapper for bios. I used it because no "flashing the
motherboard" was involved. I do not want to try flashing coreboot to
my motherboard.

grub2 efi works fine in my VirtualBox 3.2.8 PUEL. IN edk1 duet it has

Sorry, but i do not have a qemu image because I am using actual
hardware. I guess you are asking for qemu image of my DUET USB
pendrive. Can you provide link to instructions on how to create one?
Can virtualbox be used to create the image.
