Watchdog
Watchdog (JWD1) is a system monitor that can reboot the system when a software application
hangs. Close pins 1-2 to reset the system if an application hangs. Close pins 2-3 to generate
a non-maskable interrupt (NMI) signal for the application that hangs. Refer to the table below
for jumper settings. The Watchdog must also be enabled in the BIOS.
