Endian control depends on the CPU type (BookE has per page E bit,
6xx/7xx desktops have a global endian mode, and G5s don't have little
endian support at all).
It's useless but for old versions of Windows NT, which means it's
useless, period. :)

If you look at the MOL bk web front end, you'll see an openbios dir
in there)
