2.Installation and Settings

CAUTION

Electrostatic discharge (ESD) can damage components. Perform the procedures

described in this chapter only at an ESD workstation. If such a station is not

available, you can provide some ESD protection by wearing an anti-static wrist

strap and attaching it to a metal part of the computer.

Jumper Settings

The motherboard contains configuration jumpers that make it possible to change the

system configuration. Normally, the only time you will ever change a jumper is if you

need to:

• Change the system operating speed

• Clear CMOS

• Clear Password

• Change the Onboard LAN Power Supply voltage source

✏NOTE

A jumper is a small plastic-encased conductor that slips over jumper pins. To change a

jumper setting, use a pair of fine needle-nosed pliers to remove the jumper from its

current location and slide it onto the new pins to obtain the desired setting.

CAUTION

Do not squeeze the pliers or other tool you use to remove a jumper, or you might bend

or break the pins.
