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 don't use qemu often, but filo, grub2, or seabios for paylaods to boot
gpt.

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.
You could read up on the cbfs header to understand how the addressing would
work.
Thanking You!
Ganesh
