So far I have gathered that grub uses the GOP ( Graphics Output
Protocol ) EFI interface for graphics.  Am I correct in assuming that
interface is implemented via an EFI option rom driver on the video
card, or a bios fallback?  It seems that my system is limited to a
simple text mode ( and the EFI shell could upgrade it to only a
slightly higher line count mode, didn't even get to 50 ).  Is this a
limitation of my particular interface, or the GOP protocol?  In other
words, if I had a different video card, could grub-efi possibly run
gfxmenu?
