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/Disable
JWD is used to enable Watch Dog, a system monitor that can reboot the system when a software ap- plication hangs. Pins
