I don't want to get too argumentative here( I really do appreciate all your 
advice) but is this true?

The ATX power supply on my machine will come on %100 of the time with no 
processor installed, provided I don't plug in that 4 pin connector.

On the embedded IA32 systems I've worked on (About Pentium class) The ATX 
power control is actually located in the "super IO" chip, which is integrated 
into the South Bridge in more modern architectures, correct?

This would indicate that the chipset would be responsible for controlling the 
ATX supply and not the CPU.

Am I off on this?

thx,
NZG.
