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 sys- tem, remove the AC power cord and then short JBT1 to clear CMOS. Do

not use the PW_ON connector to clear CMOS.

Watch Dog

JWD controls Watch Dog, a system monitor that takes action when a software application freezes the system. Pins 1-2 will have WD re- set the system if a program freezes. Pins 2-3 will generate a non-maskable interrupt for the pro- gram that has frozen (requires soft- ware implementation). Watch Dog must also be enabled in BIOS.
