Chapter 2

Hardware Installation

This chapter gives you a step-by-stepprocedure on how to install your system. Follow each section accordingly.

2.1ESD Precautions

Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component.

1.Do not remove a component from its protective packaging until you are ready to install it.

2.Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection.

2.3Setting the Jumper

Set a jumper as follows:

To open a jumper, remove the jumper cap.

To close a jumper, insert the plastic

jumper cap over two pins of a jumper.

The conventions in the figure are used to represent the proper jumper settings.

2.4Installing a Microprocessor

The motherboard comes with a zero-insertionforce (ZIF) microprocessor socket that allows you to install a CPU without using any tool.

Follow these steps to install a CPU into a ZIF-typeCPU socket:

Make sure that the system power is OFF before installing a component.

1.

Locate the CPU socket on the

 

system board and pull up the socket

 

lever.

 

Hole 1

2.Gently insert the CPU. Make sure that pin 1 of the CPU aligns with hole 1 of the socket. The notched corner on the CPU indicates the location of pin 1.

2.5Upgrading the Microprocessor

To upgrade a CPU:

1.Turn off the system power and remove the housing cover.

2.Locate the CPU socket on the system board.

3.Pull up the socket lever.

4.Remove the installed CPU, if any.

5.Install the upgrade CPU. Refer to section 2.4 for instructions on how to install a CPU.

2.6Configuring the System Memory

The system board has four 72-pinSIMM sockets that allow you to expand the system memory to 512 MB. The SIMM sockets acceptsingle-densityanddouble-densitySIMMs with60-nsor70-nsDRAM speed. See the figure in section 2.2 for the location of the SIMM sockets.

The following table lists the possible SIMM configurations:

2.6.1 Installing a SIMM

Observe the ESD precautions when installing components.

Follow these steps to install a SIMM:

1. Slip a SIMM at a 45° angle into a socket. If the SIMM does not completely fit into the socket, reverse the SIMM orientation. The

SIMM has a curved edge indicating

pin 1 that ensures installation in

one direction only.
