It will continuously monitor PC critical counter function. The PCI watchdog card only requires that you have a PCI slot available and a PC with a reset switch. The reset cable is disconnected from the motherboard and plugged into the PCI watchdog card. A cable is provided to go from the watchdog board to the motherboard. When the PC locks up and the watchdog times out, then it will perform the equivalent of a push-button reset.
