Hardware Installation

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

2.1 ESD 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.

2.4 Installing a Microprocessor

The motherboard comes with a zero-insertion force (ZIF) microprocessor
socket that allows you to install a CPU without using any tool.
Follow these steps to install a CPU into a ZIF-type CPU 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.

3. Pull down the socket lever to lock
the CPU into the socket.
