Many modern PC BIOS' now omit the option of setting the NumLock to a state of
"OFF" when the system boots.  For us old timers, we still use that pad for
arrow keys, not numbers, so we still want that set to off at boot time.  If 
you still use Win 9X or DOS, then stuff this in your autoexec.bat and you are 
set.  It also works as you might expect in DOS boxes.  The author is me (Paul 
Hsieh).
