JBMC1

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.
