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 clear-

ing 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

hangs. See the table on the right for jumper set-

tings. Watch Dog must also be enabled in the

BIOS.
