Watch Dog Enable/Disable

JWD enables the Watch Dog func- tion. Watch Dog is a system moni- tor that can reboot the system when a software application is "hung up". Pins 1-2 will cause WD to reset the system if an applica- tion is "hung up". Pins 2-3 will generate a non-maskable interrupt signal for the application that is "hung up". See the table on the right for jumper settings. Watch Dog can also be enabled via BIOS. (*Note, when enabled, the user needs to write his own application software in order to disable the Watch Dog Timer.)
