and, of course, there's always the issue that many BIOS USB stacks
will support *some*, but not *all*, keyboards. I had this recently
with a brand new Sun Ultra40. No PS/2 keyboards for them, no sir! USB!
It's the 21st century!

So, the hunt for a working USB keyboard turned up several NFG units
and one working unit.

Summary: Just because the BIOS won't support *a* USB keyboard, does
not mean it can not support some other USB keyboard.

Just to keep it interesting.
