Using the BIOS Setup Program

Using the BIOS Setup Program

Using the BIOS Setup Program

This chapter explains how to use the BIOS Setup program. You can use the Setup program to
change the computer’s configuration information and boot-up sequence, etc.

Your system uses a Phoenix BIOS, which is stored in flash memory on the motherboard. This
enables you to run the program at any time when you turn on or reset your computer.

The configuration you define through the Setup program is stored in a special area of memory
called CMOS RAM. The battery on the motherboard backs up this memory, so the memory is not
erased when you turn off or reset the computer. Whenever you reboot the computer, it checks the
settings, and if it discovers a difference between the information in the CMOS RAM and its actual
hardware configuration, it prompts you to run the Setup program.

About the Setup Program

2-2

Using the BIOS Setup Program

To enter the Setup program, turn the computer on and press DEL as soon as you see the
“emachines” logo.

If you do not press the key quickly, the computer starts loading the operating system.

When you enter the Setup program, you will see the Setup menu. The legend bar at the bottom of
the menu displays function keys used in Setup.

The Setup program is for viewing and changing the BIOS settings for a computer. Setup is
accessed by pressing the <DEL> key after the Power-On Self Test (POST) begins and before the
operating system boot begins.

The next table shows the menus available from the menu bar at the top of the Setup screen.

Entering the Setup Program

NOTE

For reference purposes, write down the current Setup settings. When you make changes to the
settings, update this record.

NOTE

The actual menus displayed on your system may differ depending on the hardware and features
installed in your computer.

Installing Board Options

This chapter describes how to install board options in your computer. You can use these
instructions to install a variety of devices and board options. Although your board options may
look a bit different from the ones illustrated herein, you can install and remove it the same way.

Before You Begin

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 can 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 antistatic wrist strap and attaching it to a metal part of the computer
chassis.

Installing Board Options

The processor that you install must be compatible with mPGA478 socket.

Installing and Removing the Processor

Installing the Processor

To install the processor, follow these steps:

1. See the illustration in “Motherboard Overview” in Chapter 1 for the location of the processor
socket.

2. Pull the ZIF handle sideways away from the socket then upward to 90-degree angles.

3. Locate the new processor you are installing over the socket so that the marked with triangle
corner on the processor can be aligned with the first blank corner on the socket. Then gently
push the processor straight into the socket until its pins are completely inserted into the holes of
the socket.

NOTE

According to processor type, your actual process may be slightly different from one described
below.

WARNING

A processor you plan to install should have a fan type heatsink attached to it to prevent
overheating. If there is no fan type heatsink, the processor may overheat and cause damage to both
the processor and motherboard.

3-3

Installing Board Options

4. Press the ZIF handle back to close it.

5. Attach the heatsink to the processor socket.

6. Connect the fan connector cable from the CPU fan to the CPU fan connector on the
motherboard.

NOTE

Depending on the model, the heatsink may vary.

NOTE

If you install the processor chip in the wrong orientation, you may burn the chip and void your
warranty.

3-4

Installing Board Options

Removing the Processor

To remove the processor, follow these steps:

1. Unplug the cable connector from the CPU fan connector on the motherboard.

2. Remove the heatsink by releasing both tabs on the heatsink that secure the heatsink to the
socket.

3. Pull the ZIF handle sideways away from the socket then upward to 90-degree angles and
carefully pull the chip straight up from the socket.

4. Press the ZIF handle back to close it.

The motherboard has two dual inline memory module (DIMM) sockets. You can increase the
amount of memory in your computer up to 2 GB.

Each DIMM socket supports the following memory features:

●

184-pin 2.5 V DIMM with gold-plated contacts

●

200/266/333 MHz Non-ECC unbuffered DDR SDRAM

●

Single or double sided DIMM in the following sizes:

Installing a Memory Module

Follow these steps to install DIMMs:

1. Release the plastic retaining clips at each end of the socket by pressing the clips outward until
they snap open.

2. Orient a DIMM to the socket so the notch in the DIMM connector are aligned with the
crossbars in the socket.

3. Press the DIMM straight down until retaining tabs snap into place around the ends of the
DIMM.

Removing a Memory Module

To remove memory modules, press the retaining clips outward simultaneously until the DIMM
disengages from the socket and then carefully remove the DIMM from the socket.

Installing Board Options

The jumpers are small electrical connectors that control various circuits or functions in your
system. Jumpers are small blocks on a circuit board with two or more pins emerging from them.
To change a jumper setting, pull the plug off its pins and carefully fit it down onto the pins
indicated.

The jumper settings in your computer are preset at the factory; however, you can alter the functions
by changing the standard settings:

●

Enable or disable the password function.

●

Clear the CMOS settings.

●

Enable or disable the FDD write protect.

●

Enable or disable the CMOS Setup control.

Changing the Jumpers

NOTE

The jumper settings and their functions are inscribed on the motherboard or label attached in
your system chassis. If you want to see the label, you need to remove the cover of your system.

CAUTION

Do not change the jumpers with the power on. Always turn off the computer and unplug the power
cord from the computer before changing the jumpers.

3-8

Installing Board Options

The 3 V, coin-cell CR2032-type battery on the mainboard provides power to the real-time clock
and CMOS RAM. It has an estimated lifetime of three years if the computer is turned off.

To replace the battery, follow these steps:

1. Turn off all peripheral devices connected to the computer and then turn off the computer.

2. Disconnect all cables from computer.

3. Remove the system cover.

4. Remove the battery out of its socket with your fingers.

6. Replace the system cover.

7. Connect all cables to your computer.

Installing Board Options

After you install or remove board options, if necessary, be sure to run Setup program to update the
configuration of your system. See Chapter 2 for detail information.

If you installed a new optional equipment and Windows has installed in your system, you need to
have Windows detects it. See Windows manual and the manual that came with your optional
equipment for detail information.
