Installation

Installing a DRAM Module

T o install a DRAM module,

• Determine the desired amount of memory and acquire the necessary DRAM
modules.

• Note that a DRAM module has a polarity notch at one end so that it fits into a
socket only one way. Hold the module by the edges. Do not touch the shiny
contacts.

• Align the DRAM module edge connector with the slot at the center of the socket.

• Position the DRAM module to the left of the socket and press the DRAM module
edge connector firmly into the socket.

If you have misaligned or only partially seated the module, remove the DRAM module
gently and reinstall it.

Installing the Processor

For easy installation of the CPU, it is recommended that you remove all
Cards in PCI slots first.

• Unpack the CPU and identify the pin 1 corner of the CPU.

• Match pin 1 of the CPU with pin 1 of the CPU socket. The pin 1 corner of the CPU
socket is designated by a small triangle printed on the motherboard.

• Carefully insert the CPU into the CPU socket and move the metal arm downward
to replace it in its original position. Change any jumper settings as detailed in the
manual.

The small circle marked on the top of the CPU designates the pin 1 corner. If a heat
sink is attached and covers the top of the CPU, identify the pin 1 corner by turning
the CPU over. Locate the small gold finger that extends from one corner of the large
central square portion of the CPU. The gold finger points towards pin 1, which is
also uniquely identified by a square pad.

Positioning the CPU incorrectly in the socket can permanently damage the CPU
and the computer when you turn on the system.

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.

BIOS Features Setup

This section allows you to configure your system for basic operation. You have
the opportunity to select the system’s default speed, boot-up sequence,
keyboard operation, shadowing and security.

Chipset Features Setup

The Chipset Features Setup option is used to change the values of the chipset
registers. These registers control most of the system options in the computer.

This section allows you to configure the system based on the specific features
of the installed chipset. This chipset manages bus speeds and access to
system memory resources, such as DRAM and the external cache. It must be
stated that these items should not be altered. The default settings have been
chosen because they provide the best operating conditions for your system.

Power Management Setup

The Power Management Setup Menu allows you to configure your system to
most save energy while operating in a manner consistent with your own style
of computer use .

PNP/PCI Configuration

This section describes how to configure the PCI bus system. This section
covers some very technical items and it is recommended that only experienced
users should make any changes to the default settings.

Integrated Peripherals

The Integrated Peripherals Setup allows the user to configure the onboard
IDE controller, floppy disk controller, the printer port and the serial ports.

Supervisor/User Password Setting

Y ou can set either supervisor or user password, or both of them. The dif ference
between them are:

Supervisor Password : Y ou can enter the Setup Program and change

the options of the setup menus.

User Password : Y ou can enter the Setup Program but cannot

change the options of the setup menus.

When you select this function, the following message will appear at the center
of the screen to assist you in creating a password.

ENTER PASSWORD:

Type the password, up to eight characters in length, and press<Enter>. The new
password will clear the previously entered password from the CMOS memory.
You will be asked to confirm the password. Type the password again and
press <Enter>. You may also press <Esc> to abort the selection and operate
without a password.

To disable a password, just press <Enter> when you are prompted to enter the
password. A message will be displayed to confirm that the password is disabled.

PASSWORD DISABLED.

Once the password is disabled, the system will reset and you can enter the
Setup Program freely.

When a password is enabled, you will be prompted to enter it every time you try
to enter setup. This prevents an unauthorized person from changing any setting
of your system configuration.

In addition, when a password is enabled, you can require the BIOS to request
a password every time your system is rebooted. This would further prevent
unauthorized use of your computer.

The password requirement is defined by the Security Option of the BIOS
Features Setup Menu. If the Security Option is set to “System”, the password
will be required both at resetting and at entering setup. If the option is set to
“Setup”, the prompt only appears when you try to enter setup.
