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: For an ATX power supply, you must completely shut down the system, remove
the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable
Watch Dog is a system monitor that can
reboot the system when a software appli-
cation 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.
