Before proceeding with the installation
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.

User friendly instructions
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 carefully step-by-step.
Installing the Mainboard 2-3
¬
Installing the Mainboard to the Casing
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.
l with spacers
l 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. After 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 panic,
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.

Introduction of BIOS 3-1
Chapter 3 Introduction of BIOS
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™ 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.
M
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. If you are not able to boot your computer anymore, please refer to
the section “Erase CMOS data” in Chapter 2.
When you start the computer, it is controlled by the BIOS program. The
BIOS first operates an auto-diagnostic for all the necessary hardware,
configurations 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 to system stability, and to ensure that your system
performs at its best. After the BIOS has achieved the auto-diagnostic and autodetection operations, it will display the following message:
PRESS DEL TO ENTER SETUP
3-2 Chapter 3
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:
Fig 3 BIOS Setup main menu
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:
l Press Esc to quit the BIOS Setup.
l Press ¡ô¡õ¡÷¡ö (up, down, left, right) to choose, in the
main menu, the option you want to confirm or to modify.
l Press F10 when you have completed the setup of BIOS parameters to
save these parameters and to exit the BIOS Setup menu.
l Press Page Up/Page Down or +/- keys when you want to modify the
BIOS parameters for the active option.

CMOS DATA
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 in doing
so, you will loose all CMOS data, therefore, we recommend
that you write down all the parameters of your hardware, or to
put a label with these parameters on your hard disk.
Introduction of BIOS 3-3
¬
CPU Setup
The CPU can be setup through a programmable switch (CPU SOFT
MENU™), 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.
¡i

CPU Name Is:
ä Intel Pentium II MMX
Fig 3-1 CPU SOFT MENU™
3-4 Chapter 3
CPU Operating Speed:
This option sets the CPU speed. In this field, the CPU speed is
indicated like this: CPU speed (external clock x multiplier factor)
Select the CPU speed according the type and the speed of your CPU.
¡i Note 1 ¡j For Intel Pentium II MMX CPUs, you can
choose the following settings:
ä 233 (66x3.5) ä 266 (66x4)
ä 300 (66x4.5) ä 333 (66x5)
¡i Note 4 ¡j User define external clock and multiplier
factor:
ä User Define
/ External Clock:
ä 66MHz ä 75MHz
ä 83MHz ……………
/ Multiplier Factor:
You can choose the following multiplier factors:
ä 2.0 ä 2.5
ä 3.0 ä 3.5
ä 4.0 ä 4.5
ä 5.0 ……………
However, differences will exist because of the
various brands and types available.
Normally, we do not recommend 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:
This item will only be displayed if your CPU external clock supports
Turbo mode.
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. Do not
use this feature.
äDisable: CPU external clock is operating within
the normal limits.
äEnable: CPU external clock is operating within
the limits of the Turbo mode.
Introduction of BIOS 3-5
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In
this case, turn the system off than on again. The CPU will automatically use its
standard parameters to boot. You can then enter BIOS Setup again and set up
the CPU clock.
If you can’t enter BIOS setup , you must try turning the system on a few
times (3~4 times) and 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:
The mainboard have been designed in such a way that you can turn the
system on after having inserted the CPU in the slot 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™. However, if the CPU brand and type
is the same, and 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 set
up CPU parameters again.
3-6 Chapter 3
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.
Attention: After setting up the parameters and you leave the
BIOS SETUP, and you have verified that the system
can be booted, do not press the Reset button or turn
off the power supply. Otherwise the BIOS will
not read correctly, the parameters will fail and you
must enter CPU SOFT MENU™ again to set up the
parameters all over again.
Introduction of BIOS 3-7
-
Standard CMOS Setup Menu
It is the basic configuration parameters of the BIOS. These parameters
include the settings of date, hour, VGA card, FDD and HDD.
Fig 3-2 Standard CMOS Setup Menu
l Set up of HDD operating mode ¡i NORMAL, LBA,
LARGE ¡j
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.
ä 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.
3-8 Chapter 3
ä 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. The HDD AUTODETECTION option in the
Main Menu will automatically detect the parameters of your
hard disk and the mode supported.
ä 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.
l 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.
2 For further information about HDD installation, refer to Appendix B.

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.
Fig 3-3 BIOS Features Setup
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.
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.
3-10 Chapter 3
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:
ä A, C, SCSI
ä C, A, SCSI
ä C, CD-ROM, A
ä CD-ROM, C, A
ä D, A, SCSI (at least 2 IDE HDD can be used)
ä E, A, SCSI (at least 3 IDE HDD can be used)
ä F, A, SCSI (at least 4 IDE HDD can be used)
ä SCSI, A, C
ä SCSI, C, A
ä A, SCSI, C
ä 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:.
Introduction of BIOS 3-11
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 NumLock Status:
ä On: At boot up, the Numeric Keypad is in numeric mode.
ä 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.
2 For further details about hard disk drive installation, refer to appendix B.
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):
When you press a key continuously, the keyboard will repeat the keystroke
according to the rate you have set. (Unit: characters/second ¡^
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

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.
ä 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.
ä 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 using for support some old model or special type of hard disks
or CD-ROMs . Because the BIOS may not detect those kinds of
devices during system booting .
OS Select For DRAM > 64MB:
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.

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 (use the LOAD SETUP DEFAULTS
option).
Fig 3-4 Chipset Features Setup
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.
Auto Configuration:
This option allows (Enable) or prevents (Disable) the BIOS from using
default values for Auto Configuration. The BIOS default is Enable.
ä When you select Enable, the BIOS will automatically use the values
related to DRAM. You will not be able to set up the following options.
ä When you select Disable, you can manually set up DRAM options.
3-16 Chapter 3
Attention:Unless you are very familiar with your computer and with the
DRAM configuration and speed, we recommend you not
change the DRAM options but enable this option.
DRAM settings:
The other DRAM settings are all closely related to hardware. If you do not
understand this very well, don’t make any changes. Our BIOS is able to
auto detect the characteristics of your DRAM and to choose the best
settings.
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 block located between 15M and 16M,
and this memory block has a size of 1M. We recommend that you disable
this option.
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
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:
Fig 3-5 Power Management Setup Menu
3-18 Chapter 3
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:
ä User Define
User Define defines the delay for accessing the power modes.
ä 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
ä Max Saving
When the three saving modes are enabled, the system is set up for
maximum power savings.
Doze = 1 minute
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”.
Introduction of BIOS 3-19
Video Off After:
Select the saving mode in which the video is switched off.
ä NA
The video will never be switched off in no saving mode.
ä Doze
The video will be switched off in all saving modes.
ä Standby
The video will only be switched off in Standby or Suspend mode.
ä 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, 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).
3-20 Chapter 3
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 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 turn 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.
Resume by Ring:
To connect a external modem with the onboard serial port, the system will
be turned on when telephone ring-up.
Resume by Alarm :
RTC alarm can turn on the system . You can set date ( of month )
and time ( hour , minute , second ) .
Reload Global Timer Events
When one of the specific occurs( VGA, IRQ, IDE, FDD, serial port,
parallel port, mouse …..), 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.

PnP OS Install :
Device resource assigned by PnP OS or BIOS.
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
ESCD (Extended System Configuration Data)
Knowledge
The ESCD contains the IRQ, DMA, I/O Port, Memory
information of the system. This is a specification and a feature
specific to Plug & Play BIOS.
3-22 Chapter 3
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.
ä PCI-Auto: The onboard BIOS auto-detects which PCI slot has an IDE
card inserted in.
ä 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.
ä 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#).
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.
Introduction of BIOS 3-23
On board Serial Port 1:
This is used to specify the I/O address and IRQ of Serial Port 1. Ten

On board IDE-1 Controller:
Onboard PCI IDE 1 controller can be set as Enable or Disable.
/ Master drive Mode:
ä Auto: the BIOS can auto-detect the transfer mode of the HDD in
order to set its data transfer rate. (Default)
ä PIO Mode 0 ~ 4: User can specify the PIO mode of the HDD in
order to set its data transfer rate.
/
Slave drive Mode:
ä Auto: the BIOS can auto-detect the transfer mode of the HDD in
order to set its data transfer rate. (Default)
ä PIO Mode 0 ~ 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 Mode:
ä Auto: the BIOS can auto-detect the transfer mode of the HDD
installed in order to set its data transfer rate. (Default)
ä PIO Mode 0 ~ 4: User can specify the PIO mode of the HDD in
order to set its data transfer rate.
/ Slave drive Mode:
ä Auto: the BIOS can auto-detect the transfer mode of the HDD
installed in order to set its data transfer rate. (Default)
ä PIO Mode 0 ~ 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 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.

Appendix B General Discussion
About HDD Installation
Most of the present HDDs use IDE interface. Installing an IDE hard disk
does not require a lot of know ledge like installing the driver for a SCSI hard disk,
but this means that the user often must install the hard disk by himself and cope
with all the problems he may encounter. Here, we will try to help you solve
these potential problems.
The data stored in the hard disk are accessed through the chipset located on
the mainboard. You might often hear about the PIO mode, Master mode or
DMA mode of HDD. These modes reflect the way data is transferred from and
to the IDE drive and the mainboard.
What is the PIO mode? When the system needs to access hard disk data,
the CPU delivers input/output (I/O) orders through the chipset on the mainboard
to the hard disk drive, and t han puts these data into the system memory. This is
the PIO mode.
What is the Master mode? When the s ystem needs to access hard disk data,
these data are directly accessed from the hard disk by the chipset on the
mainboard (using a DMA or a PIO mode), and then the data is put into the
memory. In this case, t he CPU does not participate in the data transfer.
What is the DM A mode? Usually, DMA mode refers to accessing the hard
disk data by the chipset, it does not refers to data transfer mode.
Here are s ome examples of data transfer rates for IDE HDD w ith PIO
interface:
PIO Mode 0 The fastest data transfer rate reaches 3 .3Mbyte/s ec
PIO Mode 1 The fastest data transfer rate reaches 5 .2Mbyte/s ec
PIO Mode 2 The fastest data transfer rate reaches 8 .3Mbyte/s ec
PIO Mode 3 The fastest data transfer rate reaches 1 1.1Mbyte/sec
PIO Mode 4 The fastest data transfer rate reaches 1 6.6Mbyte/sec
App endix BB-2
The higher the M ODE value is, the best is the hard disk data transfer rate.
But this does not mean that you can select the highes t mode value as you like.
You must be sure that your hard disk supports that type of fast data transfer,
otherwise your hard disk will not be able to operate correctly.
Here are some examp les of data transfer rates for IDE HDD with DMA
mode:
DMA Mode 0 The fas test data transfer rate reaches 4 .16Mbyte/sec
DMA Mode 1 The fas test data transfer rate reaches 1 3.3Mbyte/sec
DMA Mode 2 The fas test data transfer rate reaches 1 6.6Mbyte/sec
Usually, PIO mode means that the hard disk data are accessed b y the CPU
through the chipset and placed into memory, and the chipset is using PIO mode
to acces s hard disk data.
MASTER mode means that hard disk data are accessed by the chipset, and
that the chip set places the data into memory. The chip set is using DMA or PIO
mode to access data stored in the hard disk drive. The Master mode can reduce
the CPU load, especially in a Multi-task environment. This can help system
p erformance.
General Discussion about HDD Installation
Installing a hard disk:
In the
♦
Standard CMOS Setup Menu
Primary means the first connector on the mainboard, that is,
,
connector IDE1 on our mainboard.
Secondary means the second connector on the mainboard, that is,
♦
connector IDE2 on our mainboard.
Two HDDs can be connected to the each connector:
♦
The first HDD is referred to as Master,
The second HDD is referred to as Slave.
The Master or Slave status of the hard disk drive is set on the hard
disk itself. Refer to the hard disk drive manual.
Installing one HDD : The red line on the connection cable must be lined up with pin 1 on the connector.
Be sure that your hard disk drive is set at Master. Actually, most hard
disk drives are set at Master as a default, so you don’t need to adjust
any setting. Just connect one end of the 40 pin cable on the drive
connector, and the other end to connector IDE1 on the mainboard.
B-3
Installing one HDD + one CD-ROM drive:The red line on the connection cable must be lined up with pin 1 on the connector.
Method 1:Set the HDD at Master, and the CD-ROM drive at Slave.
Connect one connector of the 40-pin cable to the hard disk,
another one to the CD-ROM drive, and the other end to
connector IDE1 on the mainboard.
Method 2:Set the HDD as Master and connect one end of the 40-pin
cable to the HDD, and the other end to connector IDE1 on
the mainboard.
You can ignore the setting of the CD-ROM drive, just
connect one end of the 40-pin cable to the CD-ROM drive,
and the other end to connector IDE2 on the mainboard.
We recommend you use this kind of connection, which has
no influence on HDD speed.
Appendix BB-4
Installing two HDDs: The red line on the connection cable must be lined up with pin 1 on the connector.
Method 1:Set the hard disk drive used for boot up at Master, and the
other drive at Slave. Connect one of the connectors of the
40-pin cable to the first drive, another connector to the
second drive, and the other end of the cable to connector
IDE1 on the mainboard.
Method 2:Set the hard disk drive used for boot up at Master, connect
one end of the 40-pin cable to the drive, and the other end
to connector IDE1 on the mainboard.
Set the other hard disk drive at Master, connect one end of
the 40-pin cable to the drive, and the other end to
connector IDE2 on the mainboard.
Installing two HDDs + one CD-ROM drive: The red line on the connection cable must be lined up with pin 1 on the connector.
Method 1:Set the hard disk drive used for boot up as Master, set the
other HDD at Slave, connect one connector of the 40-pin
cable to the first drive, another connector to the second
drive, and the other end of the cable to connector IDE1 on
the mainboard.
You can ignore the setting of the CD-ROM drive. Connect
one end of the 40-pin cable to the drive, and the other end
to connector IDE2 on the mainboard.
We recommend you use this method, which has no
influence on HDD speed.
Method 2:Set the hard disk drive used for boot up at Master, connect
one end of the 40-pin cable to the drive, and the other end
to connector IDE1 on the mainboard.
Set the other hard disk drive at Master, and be sure that the
CD-ROM drive is set at Slave. Most of CD-ROM drives
are set at Slave as a default, so you will normally not have
to set the CD-ROM drive. After you have verified the
settings, connect one connector of the 40-pin cable to the
HDD, another connector to the CD-ROM drive, and the
other end of the cable to connector IDE2 on the
mainboard.
General Discussion about HDD Installation
Installing three HDDs: The red line on the connection cable must be lined up with pin 1 on the connector.
Method 1:Set the hard disk drive used for boot up at Master, set the
second drive at Slave. Connect one connector of the 40-pin
cable to the first drive, another connector to the second
drive, and the other end of the cable to connector IDE1 on
the mainboard.
Set the other (the third) drive at Master, and connect one
end of the 40-pin cable to the drive, and the other end to
connector IDE2 on the mainboard.
Method 2:Set the hard disk drive used for boot up at Master, and
connect one end of the 40-pin cable to the drive and the
other end to connector IDE1 on the mainboard. Set

Using FDISK: (DOS command)
This command is found in the DOS disks.
FDISK is a tool used to organize and to partition the hard disk. The
hard disk must have been partitioned b efore use. You can create one
uniq ue partition on the hard disk, or create several p artition and use a
different Op erating System on each partition. Just don’t forget that
you have to specify an Active p artition, otherwise your hard disk will
not be bootable. For further information about FDISK, refer to the
FDISK section in the DOS user’s manual.
After you have partitioned the hard disk w ith FDISK, the system will
reboot automatically. Boot from a system floppy disk, and type

Using FORMAT: (DOS command)
This command is found in the DOS disks.
FORMAT is used to format the hard disk. The HDD have to be
