Chapter 2: Installation

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 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. Do not

use the PW_ON connector to clear

CMOS.

Watch Dog Enable

JWD controls Watch Dog, a system monitor that takes action when a soft- ware application hangs. Close pins 1-2 to reset the system if a program hangs. Close pins 2-3 to generate a non-mask- able interrupt for the program that has frozen (requires software implementa- tion). Watch Dog must also be enabled in the BIOS.
