INTRODUCTION

This mainboard is designed for the new generation CPU. It supports the Intel
CPU SLOT1 (Pentium® II), up to 512MB of memory, super I/O, and Green

PC functions. The mainboard provides high performance for the server
system and meets the requirements of the desktop system for multimedia in
the future.

This mainboard based on the new 440BX chipset which revolutionizes the
way Pentium® II PCs use memory by employing an Open Page Architecture,
a new memory architecture that lets the CPU access main memory faster.
Essentially, this means the CPU can leave a virtual finger in up to 32 different
pages of its memory, making it easy for you to flip back to any of them at any
time. Currently, like a dogged A-to-Z reader of the encyclopedia, a Pentium II
can only keep its memory open to one page at a time. The CPU uses pages
of memory in a similar manner to people leafing through reference works. It
wants to flip back and forth between a particular set of pages at a time.
Flipping right to them instead of taking that extra microsecond to find them
makes the whole PC runs faster.

Another improvement in the chipset helps the CPU when it finds a single-bit
error while reading error-correcting memory (that is, one bit in a byte of
information is incorrect). With the 440BX, the error can be corrected on the
fly, with the correction written back into memory. Current Pentium ® IIs can’t
write the correction back.

However, this mainboard offers more obvious improvements. Most
importantly, support for the faster system bus will have a profound effect on
performance.

But other performance benefits accrue for mainstream desktops as well. The
most obvious of these is support for 2x AGP. This means the AGP bus is
clocked twice as fast and Sideband channel (a slower side channel for control
information) is also used. Current AGP implementations only use a single­speed main channel and mix control information with the data.

Mainboard Installation

This BX6 mainboard not only provides all standard equipment for classic
personal computers, but also provides great flexibility for meeting future
upgrade demands. This chapter will introduce step by step all the standard
equipment and will also present, as completely as possible, future upgrade
capabilities. This mainboard is able to support all Intel Pentium II processors
now on the market.

!! WARNING !!

Discharge static electricity by

touching the GROUND such as

metal part of your case connected

with good power ground before
you handle the electronic circuit

boards.

Before installing the mainboard please be sure to turn off or disconnect the
power supply unit. Before making any modifications to the hardware
configuration of the mainboard, the power supply to any areas of the mainboard
you plan to modify should be turned off to avoid unnecessary damage to the
hardware.

12

Installing the Mainboard

Our objective is to enable the novice computer user to perform the
installation by themselves. We have attempted to write this document in
a very clear, concise and descriptive manner to help overcome any obstacles
you may face during installation. Please read our instructions carefully and
follow them step-by-step.

Most computer cases will have a base on which there will be many mounting
holes that allows the mainboard to be securely attached and at the same
time, prevents short circuits.

There are two ways to attach the mainboard to the base.

• with spacers

• or with bolts

In principle, the best way to attach the motherboard is with bolts, and only if
you are unable to do this should you attach the board with spacers. Take a
careful look at the mainboard and you will see many mounting holes on it.
Line these holes up with the mounting holes on the base. If the holes line up,
and there are screw holes this means you can attach the mainboard with
bolts. If the holes line up and there are only slots, this means you can only
attach the mainboard with spacers. Take the tip of the spacers and insert it
into the slots.

After doing this to all the slots, you can slide the mainboard into position
aligned with the slots. Af ter the mainboard has been positioned, check to
make sure everything is OK before putting the casing back on.

Note: If the mainboard has mounting holes, but don’t line up with the holes on
the base and their are no slots to attach the spacers, don’t worry, you can still

attach the spacers to the mounting holes. Just cut the spacers (along the
dotted line) (the spacer may be a little hard so be careful of our hands). In this
way you can still attach the mainboard to the base without worrying about
short circuits.

Standard External Connectors

Inside the case of any computer several cables and plugs have to be
connected. These cables and plugs are usually connected one-by-one to
connectors located on the mainboard. You need to carefully pay
attention to any connection orientation the cables may have and, if any,
notice the position of the first pin of the connector. In the explanations

that follow, we will describe the significance of the first pin.

The BIOS is a program located on a Read Only Memory chip on the
mainboard. This program will not be lost when you turn the computer off. This
program is also referred to as the boot program. It is the only channel for the
hardware circuit to communicate with the operating system. Its main function
is to manage the setup of the mainboard and interface cards parameters,
including simple parameters such as time, date, hard disk drive, as well as
more complex parameters such as hardware synchronization, device
operating mode, CPU SOFT MENU™ II techniques, setup of CPU speed.
The computer will operate
normally, or will operate at its best, only if all these parameters are correctly
configured through the BIOS.

 Don’t change the parameters inside the BIOS unless you

know what you are doing.

The parameters inside the BIOS are used to setup the hardware
synchronization or the device operating mode. If the parameters are not

correct, they will produce errors, the computer will crash, and sometimes
you will even not be able to boot the computer after it has crashed. We
recommend that you do not change the parameters inside the BIOS unless

you are familiar with them.

When you start the computer, it is controlled by the BIOS program. The BIOS
first operates an auto-diagnostic for all the necessary hardware, configures
the parameters of the hardware synchronization, and detects all the
hardware. Only when these tasks are completed does it give up control of the
computer to the program of the next level, which is the operating system.
Since the BIOS is the only channel for hardware and software to
communicate, it will be the key factor for system stability, and to ensure that
your system performs at its best. After the BIOS has achieved the auto­diagnostic and auto-detection operations, it will display the following
message:

PRESS DEL TO ENTER SETUP
Three to five seconds after the message is displayed, if you press the Del

key, you will access the BIOS Setup menu. At that moment, the BIOS will
display the following message:

20

In the BIOS Setup main menu of Figure 3, you can see several options. We
will explain these options step by step in the following pages of this chapter,
but let us first see a short description of the function keys you may use here:

❖ Press Esc to quit the BIOS Setup.
❖ Press    ➔ (up, down, left, right) to choose, in the main

menu, the option you want to confirm or to modify.

❖ Press F10 when you have completed the setup of BIOS

parameters to save these parameters and to exit the BIOS
Setup menu.

❖ Press Page Up/Page Down or +/- keys when you want to

modify the BIOS parameters for the active option.

CMOS DATA

Computer
Knowledge

Maybe you have heard somebody saying that their
CMOS DATA was lost. What is the CMOS? Is it
important? The CMOS is the memory used to store
the BIOS parameters that you have configured.
This memory is passive. You can read its data, and
you can also store data in it. But this memory has
to be powered by a battery, in order to avoid any
loss of its data when the computer is turned off.
Since you may have to change the CMOS battery
when it is out of power and indoing so, you will
loose all CMOS data, therefore, we recommend
that you write down all the parameters of your
hardware.

CPU SOFT MANU™ II

21

The CPU can be setup through a programmable switch (CPU SOFT MENU
™ II), that replaces traditional manual hardware configuration. This feature
allows the user to complete more easily the installation procedures. You can
install the CPU without configuring any jumpers or switches. The CPU must
be setup according its specifications.

In the first option, you can press <F1> at any time to display all the items that
can be chosen for that option.

CPU Operating Speed:

This option sets the CPU speed.
In this field, the CPU speed is indicated like this: CPU

speed (external clock rate x multiplier factor) Select the
CPU speed according to the type and speed of your
CPU.

Select the CPU speed according to the type and speed of your CPU.

However, differences will exist because of the various types of Intel Pentium

®

II CPUs available.

Norm ally, we do not recomm end that you use the “User Define” option to

setup CPU speed and multiplier factor. This option is for setup of future CPUs
whose specifications are still unknown. The specifications of all present CPUs
are included in the default settings. Unless you are very familiar with all CPU
parameters, it is very easy to make mistakes when you define by yourself the
external clock and the multiplier factor.

Turbo Frequency:

The Turbo mode allows you to speed up the external clock by approximately

2.5%. This feature is used to verify the design flexibility. It is a very important
tool for test units to verify CPU stability.

Enable:

CPU external clock is operating within the limits of
the Turbo mode.

Disable:

CPU external clock is operating within the normal
limits.

Note : The increase by 2.5% of the CPU speed is not a standard feature of

this product. It is only for use by our development department to verify
that the CPU is able to work normally when CPU speed, operating
temperature and power supply are 2.5% higher or lower than the
standard values. This is to guarantee product stability. We require the
manufacturer of the Clock Generator to meet the demands of our
development department and to add a TURBO Frequency feature
used for testing purposes by our R&D department. Of course, you can
use this feature to test the stability of your own system, but after you
have tested the product, we recommend that you set it back to its
normal value in order to guarantee system stability.

Solution in case of initializing problem due to invalid CPU setup:

If the CPU parameters are not setup properly , it might be impossible to
power on and initialize system. In such case:

1. Turn the system on and off a few times(3~4 times). The system
will automatically use its standard parameters to boot.

23

2. OR: Hold INSERT key and turn POWER ON. The system will

automatically use its standard parameters to boot. You can then
enter BIOS SETUP again and set up the new parameters.

When you change your CPU:

This mainboard has been designed in such a way that you can turn the
system on after having inserted the CPU in the socket without having to
configure any jumpers or DIP switches. But if you change your CPU,
normally, you just have to turn off the power supply, change the CPU and
then, set up the CPU parameters through CPU SOFT MENU™ II However, if
the new CPU is slower than the old one, we offer you two methods to
successfully complete the CPU change operation.

Method 1:

Setup up the CPU for the lowest speed for its brand.
Turn the power supply off and change the CPU. Then
turn the system on again, and set up the CPU
parameters through CPU SOFT MENU.

Method 2:

Since you have to open the computer case when you
change the CPU , it could be a good idea to use the
CCMOS jumper to erase the parameters of the
original CPU and to enter BIOS Setup to configure
the CPU parameters again.

Attention: After you have set up the parameters and left the BIOS SETUP,
and verified that the system can be booted, do not press the Reset button
and turn off the power supply at the sometime.

Otherwise, the BIOS will not read correctly, the parameters will fail and you
must enter CPU SOFT MENU™ II to set up the parameters all over again.

CPU Power Supply:

This option allows you to switch between CPU Default and user define
voltage.

CPU Default:

System will detect CPU type and select proper
voltage automatically. When it is enabled ,the option

“Core Voltage” will show the current voltage setting

that is defined by the CPU and this will not be
changeable. We recommend is using this CPU
default setting and not changing it unless current
CPU type and voltage setting can not be detected or
not correct.

User define:

This option lets the user select the voltage manually.

You can change values of the “Core Voltage” option

lists by using the Page Up and Page Down keys.

Standard CMOS Setup Menu

This contains the basic configuration parameters of the BIOS. These
parameters include the settings of date, hour, VGA card, FDD and HDD.

Set up of HDD operating mode << NORMAL, LBA, LARGE>>

Since old operating systems were only able to support HDD whose capacity
was not bigger than 528MB, any hard disk with more than 528MB was
unusable. AWARD BIOS features a solution to this problem: you can,
according to your operating system, choose three operating modes:

NORMAL, LBA or LARGE.

The HDD AUTODETECTION option in the Main Menu will automatically
detect the parameters of your hard disk and the mode supported.

Normal mode:

Standard normal mode supports hard disks of 528MB
or less. This mode directly uses positions indicated by
Cylinders (CYLS), Heads, and Sectors to access
data.

LBA
(Logical

Block
addressing)
mode:

LBA mode supports hard disk drives up to 8.4Giga.
This mode uses a different method to calculate the
position of disk data to be accessed. It translates
Cylinders (CYLS), Heads and Sectors into a logical
address where data are located. The Cylinders,
Heads, and Sectors displayed in this menu do not
reflect the actual structure of the hard disk, they are
just reference values used to calculate actual
positions. Currently, all high capacity hard disks

support this mode, that’s why we recommend you use

this mode.

25

LARGE Mode:

When the number of cylinders (CYLs) of the hard disk
exceeds 1024 and DOS is not able to support it, or if
your operating system does not support LBA mode,
you should select this mode.

FDD supporting 3 Mode:

3 Mode floppy disk drives (FDD) are 3 1/2” drives used in Japanese computer

systems. If you need to access data stored in this kind of floppy, you must
select this mode, and of course you must have a 3 Mode floppy drive.

BIOS Features Setup Menu

BIOS Features Setup Menu has already been set for maximum operation. If
you do not really understand each of the options in this menu, we
recommend you use default values.

In each item, you can press <F1> at any time to display all the options for this
item.

Virus Warning:

This item can be set as Enable or Disable.
When this feature is enabled, if there is any attempt from a software

or an application to access the boot sector or the partition table, the
BIOS will warn you that a boot virus is attempting to access to the
hard disk.

26

CPU Level 1 Cache:

This item is used to Enable or to Disable the CPU level 1 cache.
When the cache is set at Disable, it is much slower, so the default
setting for this item is Enable. Some old and very bad programs will
make the computer malfunction or crash if the system speed is to
high. In that case, you should Disable this feature.

CPU Level 2 Cache:

This item is used to enable or to disable the CPU level 2 cache.
When the external cache is enabled, the system works faster. The
default is Enable.

CPU Level 2 Cache ECC Checking:

This item is used to enable or to disable the CPU level 2 cache ECC
checking function .

Quick power on self test:

After the computer has been powered on, the BIOS of the
mainboard will run a series of tests in order to check the system and
its peripherals. If the Quick power on self test feature is Enable, the
BIOS will simplify the test procedures in order to speed up the boot
process. The default is Enable.

Boot Sequence:

When the computer boots up, it can load the operating system from
floppy drive A:, hard disk drive C:, SCSI disk drive or CD-ROM.
There are many options for the boot sequence:

 A, C, SCSI
 C, A, SCSI
 C, CD-ROM, A
 CD-ROM, C, A
 D, A, SCSI (at least 2 IDE HDD can be used)
 E, A, SCSI (at least 3 IDE HDD can be used)
 F, A, SCSI (at least 4 IDE HDD can be used)
 SCSI, A, C

27

 SCSI, C, A
 A, SCSI, C
 LS/ZIP, C

Swap Floppy Drive:

This item can be set as Enable or Disable.

When this feature is enabled, you don’t need to open the computer

case to swap the position of floppy disk drive connectors. Drive A:
can be set as drive B:, and drive B: can be set as drive A:.

Boot Up Floppy Seek:

When computer boots up, the BIOS detects if the system has FDD
or not.

When this item is enabled, if the BIOS detects no floppy drive, it will
display a floppy disk drive error message. If this item is disabled, the
BIOS will skip this test.

Boot Up Num Lock Status:

On: At boot up, the Numeric Keypad is in numeric mode.
Off: At boot up, the Numeric Keypad is in cursor control mode.

IDE HDD Block Mode:

This item can be set as Enable or Disable.
Most of new hard disk drives (IDE drives) support multi-sector

transfers. This feature speeds up hard disk drive access
performance and reduces the time necessary to access data. When
this item is enabled, the BIOS will automatically detect if your hard
disk drive supports this feature or not, and will choose the right
settings for you. ( The default is disable )

Typematic Rate Setting:

This item allows you to adjust the keystroke repeat rate. When
enabled, you can set the two keyboard typematic control that follow
(Typematic Rate and Typematic Rate Delay). If this item is disabled,
the BIOS will use the default setting.

Typematic Rate (Chars/Sec):

28

When you press a key continuously, the keyboard will repeat the
keystroke according to the rate you have set.

Typematic Rate Delay (Msec):

When you press a key continuously, if you exceed the delay you
have set here, the keyboard will automatically repeat the keystroke
according a certain rate. (Unit: milliseconds)

Security Option:

This option can be set to System or to Setup.
After you have created a password through PASSWORD SETTING,

this option will deny access to your system (System) or modification
of computer setup (BIOS Setup) by unauthorized users.

 SYSTEM: When you choose System, a password is required

each time the computer boots up. If the correct password is not
given, the system will not start.

 SETUP: When you choose Setup, a password is required only

when accessing the BIOS Setup. If you have not set a
password in the PASSWORD SETTING option, this option is
not available.

Notice: Don’t forget your password. If you forget the password, you will have

to open the computer case and clear all information in the CMOS before you
can start up the system. But doing this, you have to reset all the options you
had set up before.

PCI /VGA Palette Snoop:

This option allows the BIOS to preview VGA Status, and to modify
the information delivered from the Feature Connector of the VGA
card to the MPEG Card. This option can solve the display inversion
to black after you have used the MPEG card.

Delay IDE Initial:

This item is used to support some old or model or special type of
hard disks or CD-ROMs , since the BIOS may not detect those kinds
of devices during system booting .

OS Select For DRAM > 64MB:

29

When the system memory is bigger than 64MB, the communication
method between the BIOS and the operating system will differ from
one operating system to another. If you use OS/2, select OS2; if you
choose another operating system, select Non-OS2.

Report No FDD For WIN 95 :

When using Windows 95 without floppy drive , please set this item to
Yes.

Video BIOS Shadow:

This option is used to define whether the BIOS on the video card
uses shadow feature or not. You should set this option to Enable,
otherwise the display performance of the system will greatly
decrease.

Shadowing address ranges (C8000-CBFFF Shadow):

This option allows you to decide if the memory block (BIOS) of an
interface card at the address C8000-CBFFF uses the shadow
feature or not. If you have no interface card using this memory
block, don’t enable this option.

Shadowing address ranges (CC000-CFFFF Shadow):

This option allows you to decide if the memory block (BIOS) of an
interface card at the address CC000-CFFFF uses the shadow
feature or not. If you have no interface card using this memory
block, don’t enable this option.

Shadowing address ranges (D0000-D3FFF Shadow):

This option allows you to decide if the memory block (BIOS) of an
interface card at the address D0000-D3FFF uses the shadow
feature or not. If you have no interface card using this memory
block, don’t enable this option.

Shadowing address ranges (D4000-D7FFF Shadow):

This option allows you to decide if the memory block (BIOS) of an
interface card at the address D4000-D7FFF uses the shadow
feature or not. If you have no interface card using this memory
block, don’t enable this option.

Shadowing address ranges (D8000-DBFFF Shadow):

30

This option allows you to decide if the memory block (BIOS) of an
interface card at the address D8000-DBFFF uses the shadow
feature or not. If you have no interface card using this memory
block, don’t enable this option.

Shadowing address ranges (DC000-DFFFF Shadow):

This option allows you to decide if the memory block (BIOS) of an
interface card at the address DC000-DFFFF uses the shadow
feature or not. If you have no interface card using this memory
block, don’t enable this option.

Computer
knowledge

SHADOW

What is the SHADOW? The BIOS of standard video
or interface cards is stored in ROM, and it is often
very slow. With the Shadow feature, the CPU reads
the BIOS on the VGA card and copies it into RAM.
When the CPU runs this BIOS, the operation is
speeded up.

Chipset Features Setup Menu

The Chipset Features Setup Menu is used to modify the contents of the
buffers in the chipset on the mainboard. Since the parameters of the buffers
are closely related to hardware, if the setup is not correct or false, the
mainboard will become unstable or you will not be able to boot up. If you

don’t know the hardware very well, use default values ( i.e. use the LOAD

SETUP DEFAULTS option).

NOTE: Chipset Features Setup Menu may display differently from above because

variety version of BIOS.

31

You can use the arrow keys to move between the items. Use "PgUP",
"PgDn", "+" and "-" to change the values. When you have finished setting up
the chipset, press "ESC" to go back to the main menu.

Memory Hole At 15M-16M:

This option is used to free up the 15M-16M memory block. Some
special peripherals need to use a memory bloc located between
15M and 16M, and this memory block has a size of 1M. We
recommend that you disable this option.

Thermal & Fan Monitor:

These items list current states of system temperature and fan
speed. It can not be changed by user.

Voltage Monitor:

This items lists the voltage states of the system power. Just like
Thermal & Fan Monitor, it is unchangeable.

There are small differences in the chipset feature setup according to different
mainboard models, but this has no influence upon performance. Our default
setup should be the best one. That is the reason why we do not describe all
the features of this menu.

Power Management Setup Menu

The difference between Green PCs and traditional computers is that Green
PCs have a power management feature. With this feature, when the computer
is powered on but inactive, the power consumption is reduced in order to save
energy. When the computer operates normally, it is in Normal mode. In this
mode, the Power Management Program will control the access to video,
parallel ports, serial ports and drives, and the operating status of the keyboard,
mouse and other device. These are referred to as Power Management Events.
In cases where none of these events occur, the system enters the power
saving mode. When one of the controlled events occurs, the system
immediately returns to normal mode and operates at its maximum speed.
Power saving modes can be divided into three modes according to their power
consumption: Doze Mode, Standby Mode , and Suspend Mode. The four
modes proceed in the following sequence:

Normal Mode===> Doze Mode===> Standby Mode===> Suspend Mode

32

The system consumption is reduced according the following sequence:
Normal > Doze > Standby > Suspend

1. In the Main Menu, select "Power Management Setup" and press "Enter".
The following screen is displayed:

2. Use arrow keys to go to the item you want to configure. To change the
settings, use "PgUP", "PgDn", "+" and "-".

3. After you have configured the Power Management feature, press “Esc”
to go back to the Main Menu.

We are now going to briefly explain the options in this menu:

Power Management:

Four options:

 User Define
 User Define defines the delay for accessing the power

modes.

 Min Saving

When the three saving modes are enabled, the system
is set up for

minimum power savings.
Doze = 1 hour
Standby = 1 hour
Suspend = 1 hour

 Max Saving

When the three saving modes are enabled, the system
is set up for

maximum power savings.
Doze = 1 minute

33

Standby = 1 minute
Suspend = 1 minute

PM Control by APM:

Power Management is completely controlled by the APM.
APM stands for Advanced Power Management, it is a power

management standard set by Microsoft, Intel and other major
manufacturers.

Video Off Method:

Three video off methods are available: "Blank", "V/H SYNC + Blank"
and "DPMS". The default is "V/H SYNC + Blank".

If this setting does not shut off the screen, select “Blank”. If your
monitor and video card support DMPS standard, select “DPMS”.

Video Off After:

Select the saving mode in which the video is switched off.

 NA

The video will never be switched off in no power saving
mode.

 Doze

The video will be switched off in all power saving modes.

 Standby

The video will only be switched off in Standby or Suspend
mode.

 Suspend

The video will only be switched off in Suspend mode.

IDE HDD Power Down:

If the system has not accessed data on the hard disk drive during
the specified time period, the engine of the HDD will stop in order to
save electricity.

You can set 1 to 15 minutes or select Disable according to your use
of the HDD.

Doze Mode:

When the setting selected for "Power Management" is "User
Define", you can define for this mode any delay from 1 minute to 1
hour. If no power management event occurs during this time period,

34

meaning that computer is inactive during this period, the system will
enter the Doze power saving mode.

If this mode is disabled, the system will enter the next mode in the
sequence (Standby or Suspend mode).

Standby Mode:

When the setting selected for "Power Management" is "User
Define", you can define for this mode any delay from 1 minute to 1
hour. If no power management event occurs during this time period,
meaning the computer is inactive during this period, the system will
enter the Standby power saving mode.

If this mode is disabled, the system will enter the next mode in the
sequence (Suspend mode).

Suspend Mode:

When the setting selected for "Power Management" is "User
Define", you can define for this mode any delay from 1 minute to 1
hour. If no power management event occurs during this time period,
meaning the computer is inactive during this period, the system will
enter the Suspend power saving mode. The CPU stops working
completely.

If this mode is disabled, the system will not enter the Suspend
mode.

Throttle Duty Cycle:

This is used to specify the CPU speed in power saving mode. Seven
options are available: 12.5%, 25.0%, 37.5%, 50.0%, 62.5% or

75.0% .

CPU Fan Off In Option:

CPU fan can be turned off in suspend mode.

Power Button Override:

Support ACPI Power Button Over-ride. The user presses the power
button for more then four seconds while the system is in the working
state, then the system will transition to the soft-off(Power off by
software). This is called the power button over-ride.

IRQ8 Break Suspend :

Support RTC alarm wake up from suspend function (via IRQ8).

35

Reload Global Timer Events

When one of the specific occurs, the count down made for entry in
power saving mode goes back to zero.

Since the computer will enter a power saving mode only after an
inactivity delay specified (time specific for Doze, Standby and
Suspend modes) and after it has no activity, during this time period,
any event will cause the computer to re-count the time elapsed.
Resume events are operations or signals that cause the computer to
resume time counting.

Resume by Ring:

If you connect an external modem to the onboard serial port, the
system will be turned on when a telephone ring-up occurs.

Resume by Alarm :

RTC alarm can turn on the system . You can set date ( of month )
and time ( hour , minute , second ) .

PCI & Onboard I/O Setup

In this menu, you can change the INT# and IRQ of the PCI bus and the
onboard I/O device, I/O port address and other hardware settings.

PnP OS Install :

Device resource assigned by PnP OS or BIOS.

36

Force Update ESCD:

If you want to clear ESCD data next time you boot up, and ask the
BIOS to reset the settings for the Plug & Play ISA Card and the PCI
Card, select Enabled. But the next time you boot up, this option will
automatically be set as Disabled.

Computer
Knowledge

ESCD (Extended System Configuration Data)

The ESCD contains the IRQ, DMA, I/O Port, Memory
information of the system. This is a specification and a

feature
specific to the Plug & Play BIOS.

Resources Controlled By:

When you select Auto, the BIOS will automatically assign the IRQ
and DMA to PCI / ISA PnP . When this option is Manual, you can
choose which IRQ or DMA can assign to PCI / ISA PnP .

PCI IDE Card 2nd Channel:

This option can be enabled or disabled. BIOS default is Enable.
Since this channel uses IRQ15, if you want to use this channel, you

have to enable this option to make the BIOS assign IRQ15 to this
channel.

PCI IDE Card IRQ Map to:

Three options are available for this item: PCI Auto, PCI-slotX and
ISA.

 PCI-Auto: The onboard BIOS auto-detects which PCI

slot has an IDE card inserted in.

 PCI-slotX: Some old PCI IDE cards cannot be

detected by the BIOS. If the onboard BIOS cannot
detect a PCE IDE card, you have to specify on which
PCI slot the IDE card is inserted, to make the BIOS
assign IRQ14 for use by the interrupt number (INT#) of
this PCI slot.

 ISA: If you select ISA, it means that your PCI IDE card

features a “paddleboard” and a cable that can be

connected to IRQ on the ISA slot, because the BIOS
will not assign any IRQ to this PCI slot.

Attention: Primary Channel and Secondary Channel : The BIOS needs two
independent interrupt number (INT#) lines to be allocated to the PCI IDE
card. Be careful not to choose twice the same interrupt number (INT#).

37

Assign IRQ for PCI VGA :

You can assign IRQ for PCI VGA or not .

On Board FDD Controller:

This is to Enable or Disable the Onboard FDD Controller.

On board Serial Port 1:

This is used to specify the I/O address and IRQ of Serial Port 1. Ten
options are available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4
or 2E8h/IRQ3.3F8h/IRQ10, 2F8h/IRQ11, 3E8h/IRQ10, 2E8h/IRQ11,
and AUTO.

On board Serial Port 2:

This is used to specify the I/O address and IRQ of Serial Port 2. Ten
options are available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4
or 2E8h/IRQ3. 3F8/IRQ10, 2F8/IRQ11, 3E8/IRQ10, 2E8/IRQ11, and
AUTO.

Onboard IR function:

Three options are available:

 IrDA (HPSIR)mode.
 ASK IR (Amplitude Shift Keyed IR)mode.
 Disabled.

RxD , TxD Active:

Set IR transmission/reception polarity as High or Low.

IR Transmission Delay:

Set IR transmission delays 4 character-time(40 bit-time)
when SIR is changed form RX mode to TX mode.

On board Parallel Port:

Set the I/O address and IRQ of the onboard parallel port. Four
options are available: Disable, 3BCh/IRQ7, 278h/IRQ5 and
378h/IRQ7. Default is 378h/IRQ7.

Parallel Port Mode:

Can be set as ECP, EPP , ECP+EPP, or Normal (SPP) mode.
Default is Normal (SPP) mode.

38

ECP Mode Use DMA:

When the mode selected for the onboard parallel port is ECP, the
DMA channel selected can be Channel 1 or Channel 3.

EPP Mode Select:

When the mode selected for the onboard parallel port is EPP, two
EPP version options are available: EPP1.7 or EPP1.9 .

On board IDE-1 Controller:

Onboard PCI IDE 1 controller can be set as Enable or Disable.

Master drive PIO Mode:

 Auto: the BIOS can auto-detect the transfer mode of the HDD in

order to set its data transfer rate. (Default)

 PIO 0~PIO 4: User can specify the PIO mode of the HDD in

order to set its data transfer rate.

Slave drive PIO Mode:

 Auto: the BIOS can auto-detect the transfer mode of the HDD in

order to set its data transfer rate. (Default)

 PIO 0~PIO 4: User can specify the PIO mode of the HDD in

order to set its data transfer rate.

On board IDE-2 Controller:

The onboard IDE-2 controller can be set at Enable of Disable.

Master drive PIO Mode:

 Auto: the BIOS can auto-detect the transfer mode of the HDD

installed in order to set its data transfer rate. (Default)

 PIO 0~PIO 4: User can specify the PIO mode of the HDD in

order to set its data transfer rate.

Slave drive PIO Mode:

 Auto: the BIOS can auto-detect the transfer mode of the HDD

installed in order to set its data transfer rate. (Default)

 PIO 0~PIO 4: User can specify the PIO mode of the HDD in

order to set its data transfer rate.
PIO MODE 0~4 reflects the HDD data transfer rate. The higher
the MODE value is, the better is the HDD data transfer rate. But it

does not mean that you can select the highest MODE value just as

39

you like, you first have to be sure that your HDD supports this
MODE, otherwise the hard disk will not be able to operate normally.

Load BIOS Defaults

BIOS defaults are the reference settings that allow your system to work at a
comparatively low performance. When you choose the option, the following
message is displayed:

“Load BIOS Defaults (Y/N)? N”

If you want to use BIOS default values, press “Y”, than <Enter>.

Load Setup Defaults

Setup defaults are the settings that allow your system to operate at its highest
performance. When you choose this option, the following message is
displayed:

“Load Setup Defaults (Y/N)? N”

If you want to use BIOS Setup default values, press “Y”, than <Enter> to

complete the loading of the settings for best performance.
You should first load the best settings, than enter the CPU Soft Menu to set

up CPU parameters, otherwise the BIOS will replace set parameters by
default parameters.

Password Setting

This option allows you to set a password required to start the system
(System) or to access to the BIOS (Setup).

After you have set a password through the PASSWORD SETTING option,

you can enter the Security Option in the “BIOS Features Setup Menu” to

select the security level in order to prevent any unauthorized access.

displayed:

“Enter Password:“

Press <Enter>, the message “Password Disable” is displayed. Press a key.

The password clearing procedure is completed.

Notice: Do not forget your password. If you forget it, you will have to open
the computer case, clear the contents of the CMOS, and boot the system up
again. By doing this, you must reset all your parameters.

IDE HDD Auto Detection

After you have installed the hard disk, in old systems, you had to know the hard
disk specifications, such as the number of cylinders, heads and sectors, and to
enter the relevant information into the hard disk information section. If the
CMOS data was erased, and you had forgotten the hard disk specifications, it
was a great problem. But now, you can use this option to auto detect the hard
disk type and specifications, and the BIOS will automatically detect all the
relevant information and place them in the Hard Disk data section of the
Standard CMOS Setup Menu, in order to allow you to use your hard disk.

INSTALLATION

This instruction will give you a simplified installation procedure, in order to
allow you to install your mainboard quickly and correctly.

you can check Hard disk Controller, make sure if the Bus Master
driver is recognized.

Step 7. Also check System Device, to verify if three devices are identified

them as well. If your screen just like one below, then the PCI bridge
driver is installed appropriated.

Technical Support

If you have a problem during operation...

In order to help our technical support personnel to quickly find out what is the
problem of your mainboard and to give you the answers you need, before
filling in the technical support form*, eliminate any peripheral that is not
related to the problem, and indicate on the form the key peripherals. Fax the
technical support form to your dealer or to the company where you bought
the hardware in order to benefit from our technical support. (You can refer to
the examples given below.)

Example 1: With a system including: mainboard (with CPU, DRAM,
COAST...) HDD, CD-ROM, FDD, VGA CARD, MPEG CARD, SCSI
CARD, SOUND CARD..., after the system is assembled, if you
cannot boot up, check the key components of the system using the
procedure described below.

First remove all interface cards except the VGA card and try to reboot.

If you still cannot boot up:

Try installing another brand/model VGA card and see if the system
will start. If it still does not start, note the VGA card model,
mainboard model, BIOS identification number, CPU on the technical
support form (refer to main instructions), and describe the problem
in the problem description space provided.

If you can boot up:

Insert back the interface cards you have removed one by one and
try to start the system each time you insert a card, until the system
doesn’t start anymore. Keep the VGA card and the interface card
that causes the problem inserted on the mainboard, remove any
other card or peripheral, and start again. If you still cannot start, note
down the information related to both cards in the add-on Card space
provided, and don’t forget to indicate the mainboard model, version,
BIOS identification number, CPU (refer to main instructions), and
give a description of the problem.

Example 2: With a system including the mainboard (with CPU,
DRAM, COAST...) HDD, CD-ROM, FDD, VGA CARD, LAN CARD,
MPEG CARD, SCSI CARD, SOUND CARD, after assembly and
after having installed the Sound Card Driver, when you restart the
system, when it runs the Sound Card Driver, it resets automatically.
This problem may be due to the Sound Card Driver. During the
Starting DOS… procedure, press SHIFT (BY-PASS) key, to skip
CONFIG.SYS and AUTOEXEC.BAT; edit CONFIG.SYS with a text
editor, and in front on the line that loads the Sound Card Driver, add
a remark REM, in order to disable the Sound Card Driver. See the
example below.

CONFIG.SYS:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE HIGHSCAN
DOS=HIGH,UMB
FILES=40
BUFFERS=36

REM DEVICEHIGH=C:\PLUGPLAY\DWCFGMG.SYS

LASTDRIVE=Z

Restart the system. If the system starts and does not reset, you can be sure
that the problem is due to the Sound Card Driver. Note down the Sound Card
model, mainboard model, BIOS identification number on the technical support
file (refer to main instructions), and describe the problem in the space
provided.
