Heh, that's funny. I must admit I'd never thought of that.
Anyway, the bios gets confused because it's trying to figure out (in a very
simple way) where the keyboard and mouse are. It's true there's lots of
voodoo in PC BIOSes; keyboard/mouse detection isn't one of them.
(As I recall, I have to have something in the port to get it enabled. Linux
doesn't seem to know how to enable it.)
