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
reset the system if a program freezes. Pins
2-3 will generate a non-maskable interrupt for
the program that has frozen (requires soft-
ware implementation). Watch Dog must also
be enabled in 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 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 connector to clear CMOS.
