Watch Dog Enable
JWD controls Watch Dog, a system
monitor that takes action when a
software application freezes the
system. Pins 1-2 will have WD re-
set the system if a program
freezes. Pins 2-3 will generate a
non-maskable interrupt for the pro-
gram that has frozen (requires soft-
ware implementation). Watch Dog
must also be enabled in BIOS.

CMOS Clear
JBT1 is used to clear CMOS. In-
stead of pins, this "jumper" consists
of contact pads to prevent the ac-
cidental 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 clearing 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 connec-
tor to clear CMOS.
