Installing a New Processor

An upgrade processor can dramatically increase general system speed and performance.
Most microprocessor upgrade kits include the following items:

• Microprocessor chip

• Installation instructions and technical data

Before installing the processor, please refer to the installation notes that
available with the CPU package.

To Install a Processor to ZIF Socket

To install the processor, follow these steps:

1. If the system microprocessor is already on the motherboard socket, you need to
remove it from the motherboard socket. The socket is a Zero Insertion Force (ZIF)
socket which has a metal arm at one side. Carefully grasp this arm, move it horizontally
away from the socket and lift it up. Eventually you will be able to lift the chip straight
up out of the socket. Be careful not to bend any pins.

Be careful not to bend any of the pins when removing the microprocessor
chip from its socket. The microprocessor chip can be permanently damaged.

2. Unpack the new microprocessor chip.

3. Carefully align the processor with the correct orientation to the socket on the
motherboard.

4. Carefully insert the processor into the socket, and move the metal arm downward to
replace it in its original position.

9

Connect the Cooling Fan Connector

The CPU should always have a Heat Sink and cooling fan attached to prevent
overheating.

Please follow the setup to install the Heat Sink and cooling fan. Then connect the
processor fan cable to the fan connector that located on the motherboard near the
processor and ensure the fan can operate. Otherwise the CPU can overheat and cause

damage to both CPU and motherboard.

Setting the Processor Speed

After you install the processor into the motherboard, set the processor speed by CMOS
setup.

BIOS Setup

This chapter discusses Award’s Setup Program built into the ROM BIOS. The Setup
Program allows users to modify the basic system configuration. This special information
is then stored in battery-backed RAM, which retains the setup information when the
power is turned off.

Starting Setup

The Award BIOS is immediately activated when you turn on the computer. The BIOS
reads the system information contained in the CMOS and begins the process of checking
out the system and configuring it. When it finishes, the BIOS will seek an operating
system on one of the disks and then launch and turn control over to the operating
system.

While the BIOS is in control, the Setup Program can be activated :

1. By pressing <Del> immediately after switching the system on, or

2. By pressing the <Del> key when the following message appears briefly at
the bottom of the screen during the POST (Power On Self Test )

Press DEL to enter SETUP

If the message disappears before you can respond and you still wish to enter Setup,
restart the system to try again by turning it OFF then ON or pressing the “RESET” button
on the system case. You may also restart by simultaneously pressing the <Ctrl>, <Alt>,
and <Delete> keys. If you do not press the keys at the correct time and the system does
not reset, an error message will be displayed and you will again be asked to ...

PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

Getting Help

Press F1 to pop up a small help window that describes the appropriate keys to use and
the possible selections for the highlighted item. To exit the Help Window press <Esc> or
the F1 key again.

In Case of Problems

If, after making and saving system changes with the Setup Program, you discover that
your computer does not reset, use the Award BIOS defaults to override the CMOS
settings.

Main Menu

Once you enter the Award BIOS CMOS Setup Utility, the Main Menu will appear on the
screen. The Main Menu allows you to select from various setup functions and two exit
choices. Use the arrow keys to select among the items and press <Enter> to accept and
enter the sub-menu.
