I don't know about the SGI kit specifically, but I do know these boxes
can be picky. I have two generic USB keyboards. One works fine
everywhere, including my 540. The other works fine everywhere except
the 540, which hangs pre-boot with the dignostics scrolling helplessly
over and over when I try this keyboard in it.
