FYI, the ``soft power switch'' normally needs the CPU to respond in order for it to work, however, there is a timeout circuit such that if the switch is held for >4 or so seconds the power supply is told to shut down. I know this won't help you find the SMP bug, but it may atleast allow you to reset the machine without pulling the power plug out of the wall. -- Rod Grimes - KD7CAX - (RWG25) rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc.
