Explanation of

Jumpers

To modify the operation of the mother- board, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of the connector. Pin 1 is identifi ed 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.

Setting

JBT1 is used to clear CMOS (which will also clear any passwords). Instead of pins, this jumper consists of contact pads to prevent accidentally clearing the contents of CMOS. To clear CMOS,

1)First power down the system and unplug the power cord(s)

2)With the power disconnected, short the CMOS pads with a metal object such as a small screwdriver

3)Remove the screwdriver (or shorting device)

4)Reconnect the power cord(s) and power on the system.

Speaker Connector

Use the header on J9 to enable either the internal or an external speaker. To use the internal system speaker, con- nect the speaker wires to pins 3-4. If you wish to use an external speaker, you should jump pins 1 and 2.
