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
• 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.
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.
Technical Reference Booklet
Installing DIMMs
1. Turn off all peripheral devices connected to the computer. Turn off the
computer.
2. Remove the computer cover and locate the DIMM sockets.
3. Holding the DIMM by the edges, remove it from its antistatic package.
4. Make sure the clips at either end of the socket are pushed away from the
socket.

5. Position the DIMM above the socket. Align the two small notches in the
bottom edge of the DIMM with the keys in the socket.
6. Insert the bottom edge of the DIMM into the socket.
7. 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.
8. Replace the computer cover.
9. 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.

Installing the Spacer
When installing the Pentium II motherboard (Baby AT), you need to insert the SP ACER 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.
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 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
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 : 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.
BIOS Setup
16
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>. 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.
