Motherboard Layout (Model Code No. - 35894500XX)

The following diagrams show the relative positions of the jumpers, connectors, major components and memory banks on the motherboard.

Warning:

All connectors on board are labeled Pin “1” at one conner. Ribbon cables should always be connected with the red stripe on the Pin “1” side of the connector.

Hardware Setup

Jumper Settings

This chapter explains how to configure the motherboard’s hardware. Before using your computer, make sure all jumpers and DRAM modules are set correctly. Refer to this chapter whenever in doubt.

CPU Speed Selection

When JP7 is installed on this motherboard, jumper is required to be set for different type of CPU installed. The CPU speed is set by JP1, JP2, and JP7, please see JP7- Ratio of Processor Core to System Bus Frequency table.

When JP7 is not installed on this motherboard, jumperless feature is implemented such that no jumper is required to be set for different type of CPU installed.

The CPU speed is set in “CPU Speed Setting” of CMOS Setup.

Notice:

1. Be sure to save the CMOS setting when exit the CMOS.

2. When System Bus Frequency is 100MHz, DIMM RAM must be PC100 standard.

3. When the system is turned on the first time or the CPU is changed, a Pentium II-133 or -200 (depends on the CPU bus speed) will be recognized and a warning message of “CPU has been changed” will appear. Please enter the CMOS setup menu to configure the CPU speed.

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.

Advanced BIOS Features

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.

Technical Reference Booklet

Advanced Chipset Features

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.

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.

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 Configurations

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.

Set Supervisor/User Password

Y ou 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.

BIOS Setup

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.
