Watch Dog
JWD controls Watch Dog, a system
monitor that takes action when a soft-
ware application hangs. Close pins
1-2 to reset the system if a program
freezes. Close pins 2-3 to generate a
non-maskable interrupt for the program
that hangs. (This requires software
implementation). Watch Dog must also
be enabled in the BIOS.
CMOS Clear
JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact
pads to prevent the accidental clearing of CMOS. To clear CMOS, use a metal
object such as a small screwdriver to touch both pads at the same time to short
the connection. Always remove the AC power cord from the system before clear-
ing CMOS. Note: For an ATX power supply, you must completely shut down the
system, remove the AC power cord and then short JBT1 to clear CMOS. Do not
use the PW_ON connector to clear CMOS.
