We sold some ATX machines to the local gas company to do real-time flow control w/ QNX, until they realized they could not do a remote reboot. We had to take back the machines. > I ended up making up my own circuit to provide a signal pulse signal to > the power supply triggered and powered off the standby power line. Works > fine.

Well, a reboot causes the machine to shutdown completely, so a BIOS fix would not work. There are some MBs that use a toggle switch instead of intermittant, but the cases are based on intermittant (reset-type) powers.
