Installation

Installing a DRAM Module

To 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.

Warning:

Turn system power off before installing and removing any device,

otherwise youll cause the system damage.

Hardware Setup

12

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.

Warning:

There is a fan attached the CPU to prevent the overheating, please

ensure that the fan can operate. Otherwise the CPU can overheat

and cause damage to both CPU and motherboard.

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.

Press PgUp or PgDn to select a numbered hard disk type

or type the number and press <Enter>. Note that the

specifications of your drive must match with those of the

drive table. The hard disk will not work properly if you enter

improper information for this category. If your hard disk drive

type is not matched or listed, you can select Type User to

define your own drive type manually.

If you select Type User, you will need to know the

information listed below. Enter the information directly from

the keyboard and press <Enter>. This information should

be included in the documentation from your hard disk vendor

or the system manufacturer.

If the controller of the HDD interface is ESDI, the selection

shall be Type1.

If the controller of the HDD interface is SCSI, the selection

shall be None .

If you select Type Auto, the BIOS will auto-detect the HDD

and CD-ROM drive at the POST stage and show the IDE for

the HDD and CD-ROM drive.

primary system monitor. Although secondary monitors are

supported, you do not have to select them in Setup.

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

You can set either supervisor or user password, or both of them. The difference

between them are:

Supervisor Password : You can enter the Setup Program and change

the options of the setup menus.

User Password : You 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.

Flash Update Procedure

A program AWDFLASH.EXE is included in the utility diskette or CD. The user is

recommended to follow the procedure below to update the flash BIOS.

1. Create a DOS-bootable floppy diskette. Copy the new BIOS file (just obtained

or downloaded) and the utility program AWDFLASH.EXE to the diskette.

2. Allow the PC system to boot from the DOS diskette.

3. At the DOS prompt, key in

AWDFLASH

and hit <ENTER>

4. Enter the file name of the new BIOS.

5. The question: Do you want to save file? is displayed.

Key in N if there is no need to save the existing BIOS content..

Key in Y if a backup copy of the existing BIOS is needed.

(A file name has to be assigned to the existing BIOS binary file.)

6. The question : Are you sure to program? is displayed.

Key in Y

7. Wait until the flash-update is completed.

8. Power down the PC system.

9. Restart the PC.

Warning:

1. If the flash memory writer utility was not able to successfully

update a complete BIOS file, the system may not boot up.

2. Make sure that the BIOS file is available for this motherboard.

3. If you encounter problem while updating the new BIOS, DO NOT

turn off your PC since this might prevent the system from booting

up. Repeat the process, if the problem still persist, use the original

BIOS file you saved to disk above to update. If it failed, you need

service.
