Explanation of

Jumpers

To modify the operation of the motherboard, jumpers can be used to choose between optional set- tings. Jumpers create shorts be- tween two pins to change the function of the connector. Pin 1 is identified with a square solder pad on the printed circuit board. See the motherboard layout pages for jumper locations.

Note: On a two-pin jumper, "Closed" means the jumper is on both pins and "Open" means the jumper is either on only one pin or completely removed.

CMOS Clear

JBT1 is not actually a jumper but consists of two contact pads. To clear the contents of CMOS, short these pads together by touching them both with a metal conductor such as the head of a small screwdriver. Note: for ATX power supplies, you must com- pletely shut down the system and remove the AC power cord before clearing CMOS.
