In 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 the system is turned on the first time or the CPU is changed, a Pentium
II-133 will be recognised and a warning message of “CPU has been changed”
will appear. Please enter the CMOS setup menu to reconfigure the CPU speed.

Installing the Retention Mechanism for Intel® Pentium®
II or Intel® Celeron® Processor
To install the retention mechanism, follow these steps:
1. Locate Slot 1 and the four attachment holes on the motherboard.
2. To position the mechanism, orient it as shown in figure. The tab on the
connector fits into a notch in the base of the mechanism. Press down on
the studs until it is firmly seated in attachment holes. When properly seated,
the base of the mechanism is flush with the 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.

Primary These categories identify the types of the two channels that
Master/Primary have been installed in the computer. There are 45 predefined
Slave/Secondary types and one user definable types in BIOS. Type 1 to T ype 45 are
Master/Secondary predefined. Type “user” is user-definable.
Slave
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

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 Setup
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:
Technical Reference Booklet
15
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>. Y ou may also
press <Esc> to abort the selection and operate without a password.
T o 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. 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.
