Watch Dog
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 program
freezes. Jumping pins 2-3 will gener-
ate 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.
Note: when Watch Dog is enabled, the user
must write their own application software to
disable the Watch Dog Timer.
