[conspire] ATX power supplies & default power up state (was: CPU upgrade questions (was ...)

Well worth noting, of course.  FWIW, Deirdre's former ShuttlePC
lunchbox-format 'server' motherboard utterly lacked such a BIOS Setup
control, and I've seen waaaaay too many examples of such ATX failure in
the years since then.  Enough that I regard it as a serious and
pervasive problem.

If you asked me to cite a motherboard brand where I would _least_ expect
to observe that problem, I would probably say 'SuperMicro'.  (I oserve
it most commonly on machines designed to be workstations -- as with the
ShuttlePC.)
