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 con-
nection. 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 application hangs
Close Pins 1-2 to reset the system if an applica-
tion hangs. Close Pins 2-3 to generate a non-
maskable interrupt signal for the application that
is hung up. See the table on the right for jumper
settings. Watch Dog must also be enabled in the
BIOS.
