Installation

Installing the Spacer

When installing the pentium motherboard (Baby AT), you need to insert the
SPACER at the corner near the DIMM sockets to provide better support for
connect future DRAM modules.

Motherboard
DIMM Socket
Spacer

Hardware Setup

12

Installing a DRAM Module

To 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.

Warning:

Turn system power off before installing and removing any device,
otherwise you’ll cause the system damage.

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.

Warning:

There is a fan attached the CPU to prevent the overheating, please
ensure that the fan can operate. Otherwise the CPU can overheat
and cause damage to both CPU and 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.

Drive B Ty pe drive B that has been installed in the computer.

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”.

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

Y ou can set either supervisor or user password, or both of them. The dif ference
between them are:

Supervisor Password : Y ou 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.

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.

P ASSWORD 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.
