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.
