Hi!
I tried booting ELILO (disk.img - in gpt), ubuntu & windows 8(iso) on QEMU but wasn't successful. I am able to boot into serial uefi shell only(a blank fully black screen). I tried std vga ROM in QEMU too but no result. Any comments/help would be grateful. Below is the serial output:

I want to try creating CBFS support in tianocore by writing a UEFI DXE Driver. Since the ROM's address will be known, raw access of memory corresponding to the ROM could be done and parsing functions provided. For CBFS located elsewhere a base address could be provided as an argument. Existing cbfstool's code could be used. I would like to know if this is a correct approach.
Thanking You! Ganesh
