Installing the Motherboard

Do not over-tighten the screws as this can stress the motherboard.

Checking Jumper Settings

This section explains how to set jumpers for correct configuration of the motherboard.

Setting Jumpers

Use the motherboard jumpers to set system configuration options. Jumpers with

more than one pin are numbered. When setting the jumpers, ensure that the jumper

caps are placed on the correct pins.

The illustrations show a 2-pin jumper. When

the jumper cap is placed on both pins, the

jumper is SHORT. If you remove the jumper

cap, or place the jumper cap on just one pin,

the jumper is OPEN.

This illustration shows a 3-pin jumper. Pins

1 and 2 are SHORT.

SHORT OPEN
