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 has frozen. Leaving the jumper
open will disable the Watch Dog fea-
ture. See the table on the right for
jumper settings. Watch Dog must also
be enabled in BIOS (setting located in
the Power Menu).
Note:
When enabled, the user needs
to write their own application software
in order to disable the Watch Dog tim-
er.
