Hi,
   Just a quick word about this technique.  Some ATX
motherboards have to be UNPLUGGED from the outlet before the
switch (jumper) is set.  This is because there is always power
running to the motherboard, even when the computer is off.
(This comes from a motherboard's web site, but I can't remember
which one (I think FIC)).
