Any ideas? > There is no soft way to do a hard boot. Perhaps I could get some feedback on what interest might be for the following product: One of our sync cards has a "watchdog timer", which can be set to "hard reboot" the PC if no interrupt is received for X seconds. (there is a jumper on the board which connects to the reset pins on your MB). If you run a simple utility you can set the timeout to ~0 and hard reboot the machine on demand. Now you probably don't want to buy a sync card for $500. to get this. But if a stripped down card (for say $150) was available would there be interest? It would be very easy to do.
