5. Insert the bottom edge of the DIMM into the socket.
6. When the DIMM is seated, push down on the top edge of the DIMM until the retaining
clips at the ends of the socket snap into place. Make sure the clips are firmly in
place.
7. If you installed a DIMM with ECC memory, start the computer and use the ECC
Configuration feature in Setup to enable the use of ECC.
Turn system power off before installing and removing any
device, otherwise you’ll cause the system damage.
Installing a New Processor
An upgrade processor can dramatically increase general system speed and performance.
Most microprocessor upgrade kits include the following items:
• Microprocessor chip
• Installation instructions and technical data
Your system may have these features built in, or support them as upgrades.
To Install a Processor to ZIF Socket
To install the processor, follow these steps:
1. If the system microprocessor is already on the motherboard socket, you need to
remove it from the motherboard socket. The socket is a Zero Insertion Force (ZIF)
socket which has a metal arm at one side. Carefully grasp this arm, move it horizontally
away from the socket and lift it up. Eventually you will be able to lift the chip straight
up out of the socket.
Be careful not to bend any of the pins when removing the microprocessor
chip from its socket. The microprocessor chip can be permanently damaged.
2. Unpack the new microprocessor chip.
3. Carefully align the processor with the correct orientation to the socket on the
motherboard.
4. Carefully insert the processor into the socket, and move the metal arm downward to
replace it in its original position.
Connect the Processor Fan Connector
There is a fan attached the processor to prevent the overheating. Connect the
processor fan cable to the fan connector that located on the motherboard near the
processor and ensure the fan can operate. Otherwise the CPU can overheat and
cause damage to both CPU and motherboard.

Installing the Spacer
When installing the Pentium II motherboard (Baby AT), you need to insert the SPACER at
the corner near the IDE to provide better support for connect the IDE connector and
future DRAM modules.

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.

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.
BIOS Setup
16
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:
DO not turn off or RESET the computer during the flash process.
If you are unsure how to upgrade the BIOS, it is best to take your
computer to an Authorized Service Center and have a trained
technician do the work for you.
