I'm not a core GRUB developer, but how would you do it? Let's see, you
have 512 bytes minus some space for the partition table. You want to
access the file system in the space. Lets see, is that fat, ext,
reiser, jfs, xfs, ntfs, lvm, raid, or something else? Do you want a
splash screen with that? Somebody will. Are you booting over a serial
line? A network card? Do you want that for linux, one of the bsd's,
windows, solaris, or beos? Is that for intel, sparc, or powerpc?
Remember, you have about 448 bytes...
