CMOS Clear
JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads
to prevent 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 1: For an ATX power supply, you must completely shut down the
system, remove the AC power cord, and then short JBT1 to clear CMOS.
Note 2: Be sure to remove the onboard CMOS Battery before you short
JBT1 to clear CMOS.
Note 3: Clearing CMOS will also clear all passwords.

Watch Dog Enable/Disable
Watch Dog (JWD1) is a system monitor that
can reboot the system when a software ap-
plication hangs. Close pins 1-2 to reset the
system if an application hangs. Close pins 2-3
to generate a non-maskable interrupt signal
for the application that hangs. See the table
on the right for jumper settings. Watch Dog
must also be enabled in the BIOS.
