Watch Dog Enable/Disable
JWD enables the Watch Dog function,
a system monitor that takes action
when a software application freezes
the system. Jumping pins 1-2 will
have WD reboot the system if a pro-
gram freezes. Jumping pins 2-3 will
generate a non-maskable interrupt for
the program that has frozen. See the
table on the right for jumper settings.
Watch Dog must also be enabled in
BIOS.
