chipset is chosen as the core logic of the mainboard to give the most outstanding
performance and reliability. It is the Micro-ATX form-factor with Socket 370
designed on the board for Pentium™ !!! processor.

Intel® i815 chipset is a high integration, high performance, power-efficient and
high compatibility device which supports Intel and non-Intel processors to PCI
bridge functionality for the complete PC99-compliant PCI system. The Intel® i815
chipset provides two channels of "PIO” and "Ultra DMA33/66 Bus Master” mode
PCI IDE ports to support the most updated Ultra DMA 66 HDD. There are one
Floppy Disk controller, two high speed Serial ports (UARTs), one multi-mode
Parallel port, one PS/2™ mouse port, one IR interface and two USB ports
(815TM5 supports up to five USB ports) designed on the board for wide variety of
peripheral connection.

According to the requirement from different customers, this mainboard will have
different feature as shown in the following table:

Model Name USB Port

815TM

Two USB Ports

815TM5

Five USB Ports

There are the 3D PCI audio and AGP VGA interfaces built on the board. These
onboard interfaces are the PnP devices (Plug and Play) and they are fully
compatible with the Windows environment. So you don't have to purchase another
sound card or VGA card because the onboard interface will meet your multimedia
requirement. ( Please refer to Section 3-5 for the installation of the device driver
for the onboard audio and VGA interfaces.)

Note: Pentium™ !!! processor is the 32-bit processor with RISC technology,
which offers several key features such as built-in L2 cache, 12-stage super-pipeline
architecture, out of order execution … etc. In order to optimize of its capabilities
and performances, the 32-bit Operating System (such as Windows 95®, Windows
98®, Windows NT® and OS/2™ …etc.) and 32-bit applications are
recommended.

1.2 AIR BUS -

There is a new interface designed on this mainboard - the AIR Bus ( CN25 ). The
AIR Bus is designed on the mainboard which will give many amazing features to
the PC system. One of the most significant and immediate feature from the AIR
Bus is the "Portable BIOS" device. The Portable BIOS" is an intelligent
device which can be connect to the AIR Bus and it will rescue the system BIOS
from virus attack and BIOS data lost.

Why AIR Bus?

Most modern mainboards use the flash ROM as the storage device to store the
system BIOS. Since the flash ROM is the programmable device and the data stored
in the flash ROM can be destroyed easily. Before we start to introduce how AIR
bus works in your PC system, please refer to the following for the potential risk
which you may found with the programmable flash ROM:

1. SYSTEM BIOS CAN BE KILLED BY VIRUS

There was a virus called CIH virus and it made users start to aware that the
virus could also make serious damage to the mainboard. Such virus will kill the
system BIOS and make PC system failed to work. Unfortunately, there is no
perfect anti-virus software which will prevent the system BIOS from virus
attack. Once the system BIOS is killed by the virus, you will be unable to start
up the PC system. There is nothing you can do about it, except send the PC
system to the supplier for troubleshooting.

2. THE RISK IS HUGE WHILE UPGRADING THE SYSTEM BIOS

In case there is the power break or system hangs while you are upgrading the
system BIOS, you will have a incomplete system BIOS in your mainboard
because only part of the new system BIOS was written into the flash ROM. Of
course, you won’t be able to use the PC system any more. Same as what
mentioned above, you have to send the PC system to the supplier for
troubleshooting.

3. WRONG BIOS CAN CAUSE SERIOUS TROUBLE

When you feel like to have the system BIOS got updated, you may have to visit
the web page of the supplier. There are so many different system BIOS included
there in the web page and you may choose the wrong one. Obviously, you will
be in a deep trouble if you are using wrong BIOS to update the system BIOS.
Whenever you are down loading the system BIOS from the web page, be sure to
double check that you are choosing the correct one. Otherwise, you will find the
PC system fail to work when you have the wrong BIOS written into the flash
ROM on the mainboard.

Intel 815 Micro-ATX Mainboard INTRODUCTION

4. FAULTY FLASH ROM MAKES PC SYSTEM FAILED TO WORK

The flash ROM is the programmable device and it has the life cycle. Defective
flash ROM does not occur very often. However, once you get a defect flash
ROM, you definitely won’t be able to use the PC system any more. Since such
problem can not be covered by online support, so what you can do is send the
PC system to the supplier for troubleshooting and then keep waiting.

Most users know how important the BIOS to a PC system. But it can be easy
destroyed because of virus attack or improper handling. Once it is damaged,
there is no way to get the PC system back to work except send the PC system
back to the supplier for troubleshooting. The system BIOS is so important yet
fragile and there seems no perfect protection to the flash ROM. In order to
provide a total solution to the system BIOS, the AIR Bus is introduced on the
mainboard and it will have the system BIOS recovered from what was
mentioned above.

How does the AIR Bus works in the PC system?

The outlook of the AIR Bus is somewhat similar to some of the connection
interfaces on the mainboard. However, there is the priority switching technology
designed on the interface and that make the AIR Bus special. Different kind of
module can be connected to the AIR Bus and give different function to the PC
system. One of the most significant function designed for the AIR Bus is the -

Portable BIOS

TM

. Basically, there is the spare copy of the system BIOS stored in

the Portable BIOS

TM

and you can use it to rescue system BIOS from different
degree of damage. Please refer to the following description and see how the
Portable BIOS

TM

will rescue the system BIOS from damage:

1: SYSTEM BIOS ATTACKED BY VIRUS:

Some virus such CIH will kill the system BIOS and make you unable to start
your PC system. There is no perfect prevention to such virus attack because

there is new virus invented everyday. Portable BIOS

TM

can not be used to

prevent virus attack. However, you can always use the Portable BIOS

TM

to

rescue the system BIOS from virus attack. Users can have the spare copy of the
system BIOS stored on the Portable BIOS

TM

. Whenever there is the virus kill

the system BIOS. Simply have the Portable BIOS

TM

connected to the AIR Bus

interface and then turn on the power, There is the intelligent software in the
Portable BIOS

TM

and it will recover the system BIOS instantly.

Intel 815 Micro-ATX Mainboard INTRODUCTION

1-4

2: POWER BREAK OR SYSTEM HANGS WHILE BIOS IS UPDATING:

Under such circumstance, the system BIOS written into the flash ROM is not
complete and you could not use it to start the PC system. Such problem is very

similar to the virus attack. So you can use the Portable BIOS

TM

to have the

system BIOS recovered. Same as what is mentioned above, have the Portable
BIOS

TM

connected to the AIR Bus and then power on the PC system. Portable

BIOS

TM

will recover the system BIOS immediately. With the Portable BIOS

TM

on your hand, you may always feel free to upgrade the system without the
potential concern.

3: WRONG BIOS WAS WRITTEN INTO THE FLASH ROM:

If you are lucky enough, you still can start the PC system and down load the
correct one from the internet and update the system BIOS. However, you may
find that the PC system does not work at all when you have updated the PC
system with wrong system BIOS. Under such circumstance, you can use the

Portable BIOS

TM

and have the system BIOS recovered instantly.

4: THE FLASH ROM ON THE BOARD IS FAULTY:

If the flash ROM on the mainboard is faulty, users have to send the PC system
(or mainboard) to the supplier for troubleshooting. It can be time and money
consuming because most PC dealer can not handle such problem. However, if
there is the AIR Bus on the mainboard, users need not to ask for the technical

support. Change the Portable BIOS

TM

to the “master mode” and then have it

connected to the AIR Bus. When you power on the PC system, Portable BIOS

TM

will replace the onboard system BIOS and use the spare copy of system BIOS
on the Portable BIOS

TM

to start the PC system.

5: DO YOU NEED TO HAVE A PORTABLE BIOS

TM

AT YOUR HAND?

Yes and No. Of course, you can use the Portable BIOS

TM

to rescue the system

BIOS immediately whenever there is the problem found in your system BIOS.
However, if you do not have the Portable BIOS

TM

at your hand, you can always

get the immediate support from your dealer. Because the Portable BIOS

TM

is

such a simple device and your dealer will surely know how to use the Portable
BIOS

TM

to rescue your system BIOS. With the AIR Bus on the mainboard, you

don’t have to wait for a long time before the PC system can get repaired.

According to what was mentioned above, you can easily find that there are so many
potential damages which can be happened to your system BIOS and make you unable to
use the PC system any more. Obviously, AIR Bus is the best solution because it will
rescue your system BIOS from all kind of damages. It is easy to use and effective. With

the AIR Bus interface designed on the board, plus the Portable BIOS

TM

recovering

2.2 AMAZING WAYS TO POWER ON THE PC SYSTEM

This mainboard has the ACPI (Advanced Configuration Power Interface) designed
on the board. When the mainboard has the ATX type power supply connected, there
are several ways to power on the system. Please read the following description for all
the details.

¨ POWER BUTTON

The power button can be programmed by COMS setup program and it has different

features. Please refer to page 3-20 for detail function description.

¨ KEYBOARD (PASSWORD OR HOT KEY)

This mainboard allows you to use your personal password or a combination of hot

key to power on your PC system. When the jumper setting on JP1 is “Enabled”, the
keyboard OnNow function will be activated. Under this circumstance, this
mainboard will keeps scanning the keyboard status waiting for the correct password
or hot key input even when the system power is off (the stand-by 5V is still working
and the power LED on the keyboard is still active). When you have selected the
keyboard hot key to power on the PC system, you will be able to use keyboard hot
key to power on the PC system. ( you can use the power button to power on the PC
system all the time.) ( Please refer to Section 4.7.- "Integrated Peripherals")

When the “Password” and “Hot KEY” is selected, you will have to reboot the PC
system to activate the setting, when you see the POST (Power On Self Test) is
completed, the setting is changed and stored in the CMOS memory. Having finished
the procedure, you may turn the power off and then you can use the keyboard to
power-on the PC system afterward.

In case that you forget the “Password” or “Hot Key”, please refer to the
jumper setting of JP9 in Section 3-4 and use JP9 to clear the Power On
password setting. When Power On password is cleared by JP9, you can
use the power button on the front panel to power on the PC system
again.

Intel 815 Micro-ATX Mainboard INTRODUCTION

¨ PS/2™ MOUSE (LEFT OR RIGHT MOUSE BUTTON)

If you have a PS/2™ mouse connected to the system, you may change the setup in

the BIOS and use the mouse click to turn on the PC system power. Please refer to
section 4.7 for the BIOS setting

To use the mouse key to turn on the PC system power, the mouse click must be done
quickly and continually. Basically, 2-5 quick clicks on the mouse key ( left key or
right key ) will turn the power immediately.

In order to activate the mouse key feature, you will have to reboot the PC system
after the BIOS setting and wait until the POST (Power On Self Test) is completed.
Having finished the procedure, you may use the mouse key to power-on the PC
system afterward..

Note: 1. This feature is not available on the COM port mouse (serial mouse).

2. To use the PS/2 mouse power-on the PC system, JP1 must be "Enabled"

¨ RTC ALARM

PC system can be waked up by the RTC setting in the CMOS. You can set the

alarming date and time in the RTC memory, When RTC alarms, the PC system will
be triggered and wakes up automatically on the date and time which you selected in
the BIOS setup program.

Enable the “Resume by Alarm” selection in the BIOS setup utility, and then you will
see the input request for the date and time. ( “Resume by Alarm” is located in the
“POWER MANAGEMENT SETUP”, please refer to Section 4.8), When you have
stored the RTC alarm setting, the PC system will be turned on automatically
according to the date and time which is recorded in the CMOS memory.

¨ MODEM RING-IN

Everyone knows that a PC system can be used as a fax machine to send or receive

fax messages. But most people still use fax machine to receive their messages
because it is not practical to have the system powered on all day long waiting for the
incoming messages. Now the problem can be solved because this mainboard can be
triggered by a modem ring-in signal.

When you have an external modem installed, you can leave the PC system power
off. Whenever there is the incoming message, the PC system will be triggered by the
ring-in signal and wake up automatically to receive the message for you. From now
on, you can tell your PC system to receive the fax message for you.

Intel 815 Micro-ATX Mainboard INTRODUCTION

2-4

In order to use the ring-in signal to wake up your PC system, you will have to use the

EXTERNAL MODEM and have it connected to one of the SERIAL PORTS (
COM1 or COM2 ) on the mainboard. When the mainboard detects the ring-in signal
from the serial port, the system power will be turned on and start to receive the
incoming messages automatically. ( you need to have the software like Award Zero­Volt Data-Suspend Utility so that you can use the fax utility to receive the incoming
fax message ). To enable the Modem Ring-In feature, you have to run the BIOS
setup utility and enable the “Power On by Ring / LAN” option (please refer to
Section 4.8 for the settings).

Note: This function is not available when using the internal MODEM card.

¨ WAKE ON LAN ( WOL )

There is a WOL connector CN16 on the mainboard which is designed to connect to
the signal from a LAN card which supports the Wake On LAN feature. When such
LAN card is installed, you may turn on the PC system from the remote server and
monitor the PC status. To enable this feature, you will have to use the BIOS setup
utility to enable the “Resume by Ring or LAN” in the BIOS setup program.

Note: This function will be disabled if you turn off the power before the system can

verify the DMI pool data.

2.3 POWER OFF THE PC SYSTEM

There are two ways to power off the system. They are “Shut Down by Power Button”
and “ Shut Down by OS”. (such as Windows® 95 and Windows® 98, you can choose
the Shut Down from the file menu and the system will be powered off immediately ).

IMPORTANT NOTICE:

“Shut down by O/S” is always recommended because “Shut Down by Power
Button” may cause data lost of wrong configuration problem. Unless your
system hangs and you can not use the “Shut down by O/S” to power off the
PC system, please do not use the power button on the front panel to power off
the PC system.

3. HARDWARE SETUP

Before you can start to install this mainboard, some hardware settings is required
to make sure it will work perfectly with the devices which you are going to install
in your PC system. To configure the mainboard is a simple task, only a few
jumpers, connectors, cables and sockets needs to be selected and configured.
(please refer to page 1-5 to see the mainboard layout)

The following connectors labeled with “optional” means they are the optional
choice for customers and the related components are normally not populated
on the mainboard.

3.1 INSTALLATION OF CPU

There is the Socket 370 CPU connector on the mainboard which is designed for
Pentium ™ !!! processor. Refer to the following diagram for the CPU socket:

CPU

When you have installed the processor onto the mainboard, it will detect the CPU
type and decide the CPU voltage automatically. So you don’t have to make any
jumper setting to select the CPU voltage and CPU FSB clock. All you have to do
is use the BIOS setting to select the CPU clock ratio. (Most CPU need not to
select the CPU clock ratio because it is "LOCKED", please refer to Section 3.4
for the switch setting or section 4-11 for the BIOS setting.)

Installation of DIMM modules:

1. Minimum one DIMM module must be installed on the mainboard.

2. Please use 3.3V PC-100 or PC-133 un-buffered DIMM module.

3. You can use single side or double side DIMM module on this mainboard.

4. You may install single bank or double bank DIMM module on the board. (please

refer to the following to configure the memory sub-system.)

5. You may choose to install DIMM module starting from DIMM1 or DIMM2.

6. Maximum memory size: 1024MB

Configuration of memory sub-system:

Intel i815 chipset supports PC-100 and PC-133 DIMM modules.
Basically, different setting in the CMOS setup program will decide the
memory speed. (refer to CMOS setup “system memory frequency” in
section 4-6). There are three different choices in the CMOS setup
program, please refer to the following for the details:

AUTO: The system BIOS will read the memory chip information stored

in the SPD chip on the DIMM module and then decide the speed
of memory frequency automatically.

100MHz: No matter what kind of DIMM module is installed on the

mainboard, the system BIOS will force the PC system running
at 100 MHz.

133MHz: When 133MHz CPU is installed on the mainboard, no matter

what kind of DIMM module is installed on the mainboard, the
system BIOS will force the PC system running at 133 MHz.
However, when 100MHz or 66MHz CPU is installed on the
mainboard, the memory frequency will be fixed at 100MHz no
matter what kind of DIMM module is installed on the
mainboard.

According to the feature of Intel i815 chipset, there is some
limitation when installing DIMM modules on the mainboard,
Different setup of “System Memory Frequency” setting in the
CMOS setup may have different requirement (refer to section 4-6

Intel 815 Micro-ATX Mainboard HARDWARE SETUP

3-4

for details), please refer to the table in the next page for details:

Note: When the CPU installed on the mainboard is 66MHz or 100MHz CPU, the

memory frequency will be 100 MHz all the time despite the setting in the
CMOS setup program..

When the CPU installed on the mainboard is 133MHz, you need to pay more
attention when configuring the memory sub-system. please refer to the following
table for the memory configuration.

System Memory Frequency Setting in CMOS

DIMM MODULES AUTO 100 MHz 133 MHz

PC-100 Single-side * 1 OK OK Not supported
PC-100 Single-side * 2 OK OK Not supported

PC-100 Double-side * 1 OK OK Not supported

PC-100 Double -side * 2 OK OK Not supported

PC-133 Single-side * 1 OK OK OK

PC-133 Single-side * 2 OK OK OK
PC-133 Double-side * 1 OK OK OK
PC-133 Double-side * 2 OK OK OK

Following is some additional information for memory installation for your reference:

1.

When the setting of "System Memory Frequency" is 100MHz, no matter what
kind of DIMM module is installed on the board, it will force the system
memory running at 100MHz.

2. When the setting of "System Memory Frequency" is 133MHz and the CPU is
also 133MHz, then the memory speed will b133MHz be all the time.

3. When the setting of "System Memory Frequency" is 133MHz but the CPU
FSB is 100MHz, then the memory speed will be reduced to100MHz despite
the type of the onboard DIMM module.

A jumper is a set of two, three or more jumper pins which allows users to make
different system configuration by putting the plastic connector plug (mini­jumper) on it. The jumper setting is necessary when installing different
components onto the mainboard.

The following jumpers which labeled with “optional” means they are the
optional choice for customers and the related components are normally not
populated on the mainboard.

Intel 815 Micro-ATX Mainboard HARDWARE SETUP

(A) JP1: Keyboard and PS/2 Mouse OnNow function selection

The Keyboard and PS/2 Mouse OnNow function is designed on the mainboard and
you can use keyboard and mouse key clicks to power on the PC system. However,
there may have some keyboard and mouse are not compatible with the OnNow
function and that will cause the PC system fail to boot. Since we can not control
what keyboard and mouse will be connected to the PC system, so there is the JP1
designed on the mainboard to control the OnNow function. Please refer to the
following picture and select the proper setting on JP1:

(B) JP2: CPU Voltage (Vcore) Range Selection (optional)

The voltage regulator on the mainboard will generate 1.3V ~ 3.5V DC to support
different processors. Basically, most mainboards will use the CPU VID signal
(VID0~VID4) from the CPU to decide the proper CPU core voltage (Vcore). In
case that there is the poor connection between CPU and its socket, or uninstall the
CPU from the mainboard while the system power is "ON". Under such
circumstance, mainboard may receive wrong VID signal and send wrong Vcore to
the CPU. Unfortunately, wrong Vcore may destroy the CPU and the mainboard.

In order to protect the mainboard and the CPU from the unexpected damage, JP2
is introduced on the mainboard to control the Vcore within the safe range so that it
won't make any damage to the CPU or mainboard because of wrong VID signal.

Since most Pentium II/!!! processors require the Vcore below 2.05V except few
Pentium II processors. So the default setting of JP2 will control the Vcore between

1.3V and 2.05V so that the CPU and mainboard will have a good protection.
Please do not change the setting on JP2 unless your CPU needs the voltage higher
than 2.05V.

(C) JP3: CPU Voltage Adjustment (optional)

Sometimes you may feel that the CPU voltage detected by the mainboard can not
meet your requirement. You want to make the CPU voltage a little bit higher than
what is detected by the mainboard. In this case, you may use the JP3 setting to
adjust the CPU voltage.

When "SHORT" is selected, the CPU voltage will be 0.05V higher then normal
setting. .

issues which will decide whether over clock will be
successful or not. For example, the VGA card, HDD,
DRAM and CPU etc. If any of the device can not meet the
over clock requirement, you will be failed when over
clocking.

connection may cause permanent damage to the mainboard. Please refer
to the following steps to clear the CMOS

1. Unplug the AC power cable from the PC system.

2. Open the cabinet of the PC system.

3. Put the mini jumper on pin 2-3 of JP11 around 3 to 5 seconds and then

return it to the original position ( pin 1-2 ).

4. Close the cabinet and Re-connect the AC power cable.

5. Power on the PC system and then run BIOS setup program to

reconfigure the PC system.

IMPORTANT:
After you have used JP11 and clear the setting which is saved in the CMOS
memory, we suggest that you use “Load Optimized Defaults” and have the
optimized parameters loaded into the BIOS setup program. Such
parameters were fine tuned and they will let you have the optimized
performance and stability.

(F) SW1: FSB Clock Selection

SW1 is designed on the board to choose the CPU FSB clock (Front Side Bus
Clock). Basically, you don't have to worry about the FSB clock setting most of the
time, because it will be detected by the mainboard BIOS automatically. However,
sometimes you may feel like to select different FSB clock for some special
purpose. In this case, you may use the BIOS setting to select different FSB clock
or use the switch setting on SW1 to force your CPU to use the selected FSB clock.

(Please do not attempt to change this setting unless you are the technician)..

jumper setting on SW1 unless you are the professional
technician.

2. When "Default" is selected, you may use SW1 to select

different speed of CPU clock and force your CPU to use that
clock speed instead of letting the system BIOS to select the
CPU clock automatically.

IMPORTANT NOTICE:
When you are changing the setting on SW1, please make sure to
remove the power core from the PC system. According to the i815
chipset feature, the PC system will hang up if you change the
setting without removing the power core.

5. How to Update the System BIOS

Before we start to discuss system BIOS update, there are some important issues
which you need to pay attention on it:

1. You can not exchange the system BIOS with another mainboard:

The system BIOS on different mainboard are different. If you take the system
BIOS from another mainboard and have it installed on this mainboard, you may
find that the mainboard fail to boot. Even the mainboard from the same
manufacturer, the content of the system BIOS can be different. So please do not
exchange the system BIOS.

2. Where to get the updated BIOS?

You can visit the web page of the supplier and down load the updated system
BIOS. Please note that you will “kill” the PC system if you have the wrong
BIOS written into the PC system. So please be sure to double check the
system BIOS before you can use it to update the system BIOS.

3. No interruption is allowed during the BIOS updating:

When the BIOS updating, please do not restart the PC system or turn the
power off. Otherwise, you will have a fragmentary system BIOS in your PC
system and it will make you unable to start the PC system. If you reset or
power off the PC system while the system BIOS is updating, you may have to
send the PC system to the suppler for troubleshooting because you do not have
the system BIOS in the PC system.

4. Do not change the onboard flash ROM:

The flash ROM is the storage device which is designed on the mainboard to
store the system BIOS. There are different kinds of the flash ROM selling in
the market. They have different capacity and different architecture. If you
install improper flash ROM onto the mainboard, it may cause unexpected
damage to the mainboard. So please never change the flash ROM on the
mainboard, otherwise, the warranty will be void.

SYSTEM BIOS UPDATE PROCEDURE

Step 1. Download the system BIOS from the web page:

1. Visit the following web page:

http://www.azza.com.tw

2.

Select “TECH SUPPORT”

3.

Down load “AWDFLASH.EXE” program.

4.

Scroll the screen downward and find the 815TM mainboard..

5.

Select the BIOS and start to down load. (Suppose the file name is

815TM.BIN)

Step 2. Prepare for the BIOS updating:

1. Windows is the multi task environment and some unexpected interruption

can be occurred and stop the BIOS updating. Since no interruption is
allowed during the BIOS updating. so the BIOS updating can not be made
under the Windows environment.

2.

Get a floppy diskette and put it into the floppy disk drive.

3.

Key-in the following command under the DOS prompt:

C:> FORMAT A:/S

4. When the diskette formatting is completed, have the files which you down

loaded from the web page copied into the floppy diskette. (815TM.BIN
and AWDFLASH.EXE).

Intel 815 Micro-ATX Mainboard AWARD BIOS SETUP

5-3

Step 3. Start to update the system BIOS:

1. Have the diskette which we made in Step 2 inserted in the floppy disk

drive..

2.

Start the PC system and click on the “del” key to start the BIOS setup

program. Select the “Advanced BIOS features” and then make sure to
select the floppy disk drive is the first boot device.

3.

Having made the boot sequence selection, save the setup and restart the PC

system.

4.

When the DOS prompt “A:>” appears, run the AWDFLASH.EXE

program. (You can use “AWDFLASH /?” to more detail of the program.)

5.

When you have started the “AWDFLASH.EXE”, it will ask you to input

the file name of the new BIOS. Key-in “815TM.BIN” and then click the
“ENTER” key.

6.

When you see the message - Do you want to save BIOS (Y/N)?. you may

choose “Y” to have the onboard BIOS copied in to the floppy diskette. If
you do not want to make the backup copy of the onboard BIOS, simply
chose “N” and start to update the system BIO. (if you want to make a
backup copy of the onboard system BIOS, then select “Y” and then give a
file name to the backup copy.)

7.

You will see from the screen whether you are going to start the BIOS

update. If you are sure that the new BIOS is correct and nothing is wrong,
chose “Y” to start the BIOS update. ( you can chose “N” and terminate the
BIOS update program.)

8.

During the BIOS updating, you will see the “Programming Flash Memory”

message display on the screen. (

IMPORTANT: you can not stop or reset

the PC system when the BIOS is updating

.)

9.

When the BIOS update is completed, remove the floppy diskette from the

floppy disk drive and restart the PC system..

10.

When you see the PC system start to boot, it indicate that the BIOS update

is successful.

11.

Click the “del” key during the Power On Self Test to trigger the BIOS

setup program..

12.

Chose "Load Optimized Default" and have the default setting written into

the CMOS memory.

13.

Chose "Save and Exit" and then restart the PC system.

14.

Having finished the procedures above, the BIOS update is completed.

Note: In case something happened that made you unable to complete the

BIOS update. You can always use the Portable BIOSTM to recover
the system BIOS. (refer to section 1-2)
