Watch Dog Enable/Disable
JWD controls the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a software
application hangs. Pins 1-2 will cause
WD to reset the system if an applica-
tion hangs. 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 must also be enabled in
BIOS. Note: When enabled, the user
needs to write their own application
software in order to disable the Watch
Dog Timer.
