Jumper Settings (JWD)
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.
Watch Dog Enable/Disable
JWD is used to enable Watch Dog,
a system monitor that can reboot
the system when a software ap-
plication hangs. Pins 1-2 will
cause WD to reset the system if
an application hangs. Pins 2-3 will
generate a non-maskable interrupt
signal for the application that
hangs. See the table on the right
for jumper settings. Watch Dog
can also be enabled via BIOS.
