Configuring the Motherboard 

 
 

Before You Begin 

!

 

CAUTION!

 

=

Always follow the steps in each procedure in the correct order. 

=

Set up a log to record information about your computer, such as model, 
serial numbers, installed options, and configuration information. 

=

Use an anti-static wrist strap and a conductive foam pad when working on 
the motherboard

!

 WARNINGS

 

The procedures in this chapter assume familiarity with the general terminology 
associated with personal computers and with the safety practices and 
regulatory compliance required for using and modifying electronic equipment.  
Disconnect the computer from its power source and from any 
telecommunications links, networks, or modems before performing any of the 
procedures described in this chapter.  Failure to disconnect power, 
telecommunications links, networks, or modems before you open the computer 
or perform any procedures can result in personal injury or equipment damage.  
Some circuitry on the motherboard may continue to operate even though the 
front panel power button is off.

 

!

 

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 chassis.
