Because It's potentially a serious security hole. If your processor
isn't physically secure. (read: locked up in a room somewhere)
anybody with some smarts and some knowledge of magic mode can
do violence (or at least dubious things) to your system if so inclined.
THAT is why they allow you to change the firmware password and smart
SAs do just that...

Yeah, they're cryptic, allright, but if any yabbo could do it, then any
yabbo could crack your system easily. Try the 'set' command when you're in
the shell at M.Mode and you'll see lots of useful shell variables and
shell functions for the more necessary functions.
