Watch Dog Enable/Disable
JWD controls the Watch Dog function.
Watch Dog is a system monitor that can
reboot the system when a software ap-
plication hangs. Pins 1-2 will cause WD
to reset the system if an application has
frozen. Pins 2-3 will generate a non-
maskable interrupt signal for the appli-
cation that is hung up. See the table on
the right for jumper settings. Watch Dog
must also be enabled in BIOS (setting
located in the Power Menu).

tings and below for the IT fi rmware
