Federal Communications Commission (FCC) Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with instructions contained in this manual, may cause harmful interference
to radio and television communications. However, there is no guarantee that interference
will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
- REORIENT OR RELOCATE THE RECEIVING ANTENNA
- INCREASE THE SEPARA TION BETWEEN THE EQUIPMENT AND THE RECEIVER
- CONNECT THE EQUIPMENT INTO AN OUTLET ON A CIRCUIT DIFFERENT FROM
THAT OF THE RECEIVER
- CONSULT THE DEALER OR AN EXPERIENCED AUDIO/TELEVISION TECHNICIAN
NOTE: Connecting this device to peripheral devices that do not comply with Class B
requirements, or using an unshielded peripheral data cable, could also result
in harmful interference to radio or television reception.

The user is cautioned that any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to operate
this equipment.
To ensure that the use of this product does not contribute to interference, it is
necessary to use shielded I/O cables.

Installation
Installing the Spacer
When installing the motherboard (Baby AT), you need to insert the SP ACER at the corner
near the DIMM sockets to provide better support for connect future DRAM modules.
Motherboard
DIMM Socket
Spacer
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
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.

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.

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.)

7. Wait until the flash-update is completed.
8. Power down the PC system.
9. Restart the PC.
