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