Watch Dog Enable/Disable
JWD enables the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a soft-
ware application is "hung up".
1-2 will cause WD to reset the sys-
tem if an application 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.)
