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.
