For PC Motherboards which don't have a reset header on the motherboard, the QUANCOM® WDOG-BTX-Kab1 can be used in conjunction with the PWDOG2N - PCI Watchdog, the ISA PC Watchdog 2 and the new Internal USB Watchdog 2 or the External USB Watchdog 3. This adaptor can also be used to reset a PC if your cabinet has a reset switch, but the motherboard does not have a reset header.
