Watch Dog Enable/Disable
USB0/1 KB/MS
JWD enables the Watch Dog function. Watch Dog is a system monitor that can reboot the system
when a software application is
"hung up". Pins 1-2 will cause WD
to reset the system 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.)
