Chapter 1 Introduction

The PowerPro VX have been especially designed for file server, workstation and
professional users. It can support a wide range of processors, including all up-to-date
Intel Pentium processors, AMD K5/K6 processors, and as well as Cyrix
6x86/6x86L/6x86MX processors. It also takes into account, as much as possible, all
future CPUs.

The PowerPro VX uses SOFT MENU™ technology, which means that all the

processor‘s parameters can be configured without using DIP switches or hardware

jumpers. The configuration is entirely achieved through a “Soft Switch” that allows the
user to set CPU speed and operating voltage with ease.

The PowerPro VX uses Intel 430VX series chip set with 512K Level-2 Pipeline
Burst SRAM on board. Two 168-pin DIMM slots meet the requirements for all memory
configurations required by higher level computing. The 168-pin DIMM slots support
fast page DRAM, EDO DRAM, and SDRAM for next generation 64-bit systems.

The PowerPro VX also provides two Universal Serial Bus (USB) ports and meets
the Concurrent PCI Rev. 2.1 standard. It also supports IDE interface for Fast HDD
(Mode 0~4) and IDE Bus Master. These features also meet present and future interface
standards and needs.

System BIOS features include Plug-and-Play (PnP), Advanced Power
Management, as well as PowerPro VX’s unique CPU operating frequency and voltage
setup feature in order to meet modern computing demands.

JUMPERS AND SWITCHES

JP3 : Delete the contents of the CMOS

This jumper is set on pins 1 and 2 at the factory default. This jumper is used
for clearing BIOS setup data in CMOS when you experience difficulties. For
instance:

⚫ You have forgotten the password you set.
⚫ You have inappropriately setup the BIOS, and the system become

unstable.

⚫ You want to change the flash BIOS to a different version.

First turn off the power switch or unplug the power core to your PC and open
the computer cover, then locate the CCMOS jumper (near the Lithium
battery) and replace the jumper on pins 2 and 3 for a couple of seconds, then
put the jumper back to operation position Pin 1 and 2 to erase the CMOS.

After you have deleted the CMOS information, you need to go back to the
BIOS Setup menu, and reset all the items correctly, such as, CPU, date, hour,

FDD and HDD parameters, and etc.

CPU INSTALLATION

Jumperless CPU Configuration Main board

You do not need to setup any jumpers or switches on the PowerPro VX main board
for CPU.

Most other main boards require you setup a bunch of jumpers or DIP switches for
the type of the CPU you plan to install. Installing a CPU is becoming more and more
complex since there are so many different kind of CPU brands and models available in
the CPU market place. Not so with PowerPro VX main board. The PowerPro VX main
board simplified the CPU installation procedure by eliminating all the jumpers for CPU.
The CPU can be easily setup by software. After you have inserted the CPU into the ZIF
(Zero Insertion Force) CPU socket, and you have installed necessary display interface
card, you can simply turn the computer on. The only thing you will need to do next is
to enter BIOS SETUP to configure the CPU speed and certain CPU parameters in the
CPU SOFT MENU™ . You may setup the CPU which is not listed with custom setting.
It reserved several circuits in order to be able to support future processors. However,
we must clarify that “we have only tested the CPUs listed in Chapter 1”, we cannot
guarantee that this board will be able to support future products, because we cannot
forecast future developments.

Related terminology :

External clock

Also referred to as the external CPU clock, or “Bus clock”, it is the input clock of

the CPU. For instance, Intel Pentium P90, P120 and P150 all have a 60MHz

external CPU clock, but have different internal clock multiplier factors.

Chapter 2

12

Clock multiplier factor

The real operation clock within the CPU is the multiple of the external clock. We

refer to this factor as the clock multiplier factor. The four factors possible are 1.5,

2, 2.5 and 3. The factor differs from one CPU to another. For instance, the Intel

Pentium 166 CPU has a 66MHz external clock, with a multiplier factor of 2.5, so

that the speed of the internal clock is 66MHz x 2.5.

Internal clock

Also referred to as the real internal CPU clock, it is the actual internal operating

clock of the CPU. The Internal Clock is a multiple of the external clock and of the

clock multiplier factor. For instance, the Intel Pentium 90 CPU has a 60MHz

external clock and its clock multiplier factor is 1.5; the Intel Pentium P133 CPU

has a 66MHz external clock and its clock multiplier factor is 2.

Internal CPU clock = clock multiplier factor * external CPU clock

AT Bus clock

Also referred to as ISA SPEED, or AT CLOCK, or even ISA Bus clock. Ten years

ago, the original specification of AT Bus clock installed in the first generation

PC/AT computers was 8MHz, this means that there are some interface cards which

can only work at 8MHz. In order to guarantee compatibility with older hardware,

we still support 8MHz AT Bus clock, but if your interface card is newer or faster,

you can choose a higher speed for the AT Bus clock, in order to increase the

transmission rate of the interface cards. But we recommend you not to be too

ambitious. An 8MHz setup ensures maximum compatibility.

CPU Voltage - Vcore and Vio

From the voltage point of view, 586 series CPU can be divided into two categories:

Single Voltage CPU and Dual Voltage CPUs. Single voltage CPUs include: Intel

Pentium P54C series, AMD-K5 and Cyrix 6x86, etc.

Dual voltage CPUs include: Intel P55C with MMX, future AMD CPUs, Cyrix

6x86L and M2.

Dual voltage CPUs requires two different voltages for the power source: Core

Voltage (Vcore) and IO Voltage (Vio). Vcore provides all the power for internal

processing, and its power consumption is quite important. Vio provides the power

necessary for the external interface of the CPU.

P-Rating

The P-Rating is defined by some CPU manufacturers other than Intel to rate the

performance of their CPU in comparison with Intel Pentium CPUs. For instance,

Cyrix 6x86 P166+ has a higher actual speed compared with Intel Pentium P166,

and its internal clock need only be 133MHz versus 166MHz for Intel’s product.

The internal architecture is different between Cyrix 6x86 and Intel Pentium CPU

even they are treated as the same type.

Main Board Installation

13

Having read the related terminology above, please refer to Appendices B, C or D for
more information of your CPU. We suggest you make a note of the specification of your
CPU, which will help you to configure your CPU correctly.

CPU Settings:

CPU SOFT MENU

To configure the speed and the voltage of the CPU, you must enter to the CPU SOFT
MENU in BIOS Setup, which is discussed in Chapter 3 System BIOS.

MEMORY MODULE INSTALLATION

When this main board was designed, we not only have taken into account the
economy and compatibility, but we also focused on the tremendous performance gain
by using SDRAM DIMM.

There are two 168-pin DIMM sockets on board. You may install up to two single
sided DIMMs on board. A total of 128MB system memory is supported.

The installation is easy. Simply push the two clips on the DIMM socket ends
outward, orientates the notches on the DIMM against the socket keys, and gently push
it down. Gradually increase the force you use, and make sure the clips are properly
snapped on the module. However, before you proceed with installation, be patient, first
following information carefully:

1. 168-pin DIMM modules specifications
According to the standards defined by JEDEC, there are different types of

specifications for 168-pin DIMM sockets. Here are the possible types:

• 3.3V UNBUFFERED DIMM

• 3.3V BUFFERED DIMM

• 5V UNBUFFERED DIMM

• 5V BUFFERED DIMM

Currently, the standard for PC is 3.3V UNBUFFERED DIMM, which is used by

this motherboard.

Since the connection between the socket and module is crucial, purchase quality

DIMM from a reliable source. The DIMM module board must have a thickness
of 1.270.1 mm. The Gold coating on the DIMM “Gold Fingers” must have a

thickness of 3 to 5 micron.

2. 60ns FastPage Mode or EDO DRAM DIMMs
If your memory modules are faster than 70ns, say 60ns or 45ns, you can modify

Chapter 2

14

the BIOS settings to speed up the operating speed of the system.

If you set the external CPU clock at 66MHz or more, we recommend you use 60ns

or even faster DRAM modules.

3. Memory error check and correction
The Intel 430VX chip set used on this main board does not support this feature,

since the memory error check and correction feature may not be effective, and
since you cannot easily find memory modules with memory check and
correction.

4. Memory modules size supported

1Mbitx64 [8MByte], 2Mx64 [16MB], 4Mx64 [32Mb], 8Mx64 [32MB], or

16Mx64 [128MB].

5. Both single sided and double sided memory modules can be used.

6. There are two 168-pin DIMM sockets on the board: DIMM 1 and 2. Please

insert the DIMM in ascending order. Note the DIMM 1 and DIMM 2 sockets
can support either single sided or double sided memory modules without any
limitation.

System BIOS

Chapter 3 System BIOS

The System BIOS is a program located on a Read-Only Memory (ROM) or Flash
ROM chip on the main board. This program will not be lost when you turn the computer
off. It is the primary channel for the hardware circuit to communicate with the operating
system. Its main function is to manage the setup of the main board and parameters of
interface cards. It setup simple parameters such as time, date, hard disk drive, as well as
more complex parameters such as hardware synchronization, device operating mode,
and also include special features such as CPU SOFT MENU™ to setup CPU voltage
and speed and store them in CMOS memory. The system BIOS configuration is one of
the key factor for your computer system stability and performance.

When the computer powers up, the System BIOS program takes the control of the
computer system. The BIOS first run an auto-diagnostic routine 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.

After the BIOS has achieved the auto-diagnostic and auto-detection operations, it
will display the following message:

PRESS CTRL-ALT-ESC OR DEL KEY TO ENTER SETUP

Three to five seconds after the message is displayed, if you press the Del key, or if
you press simultaneously the Ctrl Alt Esc keys, you will access the BIOS Setup

 Change the parameters in BIOS with caution
The parameters inside the BIOS are used to setup the hardware synchronization

or the device operating mode. If the parameters are not setup correctly, the
computer may perform poorly and sometimes may not boot up at all. 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.

Chapter 3

16

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:

⚫ 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

What is the CMOS? The CMOS referred here is a memory chip used
to store the custom BIOS configuration information, such as, Hard
Drive type, custom CPU setting, and etc. This memory device has to
be powered by a battery to maintain its content. When the CMOS
battery is out of power and the computer is not powered for a period
of time, or it has been shorted somehow, you may lose the data stored
in CMOS. Therefore, we recommend that you write down all the
custom parameters of your hardware, and save it to a safe place.

System BIOS

17

CPU SOFT MENU™

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 the installation procedures more easily. However, the CPU must be setup
according its specifications with the SOFT MENU™.

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

Fig 3-1 CPU SOFT MENU™

CPU Name Is:

Intel Pentium Intel Pentium MMX
AMD K5 AMD K6
Cyrix 6x86 Cyrix 6x86L
Cyrix 6x86MX

When you boot the computer, the main board BIOS will automatically detect
the CPU brand and type. It may use a lower CPU speed if the CPU is not recognized
properly.

Chapter 3

18

CPU Operating Speed:

This option sets the CPU speed. Different CPU brands use different techniques to

indicate the CPU speed. For example, AMD and Cyrix use P-Rating.

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.

Usually, you do not need to enter the clock and multiplier factor unless you try to

use the “User Define” CPU speed.

Note 1For Intel Pentium CPUs, you can choose the following settings:

100 (66x1.5) 120 (60x2)
133 (66x2) 150 (60x2.5)
166 (66x2.5) 200 (66x3)

Note 2For AMD-K5 CPUs from AMD, you can choose the following P-Ratings:

PR120 (60x1.5) PR133 (66x1.5)
PR166 (66x1.75)

Note 3For Cyrix 6x86 and 6x86L CPUs, you can choose the following P-Ratings:

PR120+ (50x2) PR133+ (55x2)
PR150+ (60x2) PR166+ (66x2)

Note 4User define external clock and multiplier factor:

User Define

External Clock:

50MHz 55MHz
60MHz 66MHz
75MHz 83MHz

Multiplier Factor:

You can choose the following multiplier factors:

1.5 1.75

2.0 2.5

3.0 3.5
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, especially for setup of future CPUs whose
specifications are still unknown at the time of this publication. 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. However, the BIOS will reset the CPU to a safe
speed when you turn the power on second time after the main board fail to boot.

System BIOS

19

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 for normal
operation.

Disable: CPU external clock is operating within the normal

limits.

Enable: CPU external clock is operating within the limits of the

Turbo mode.

Solution in case of booting problem due to invalid clock setup:

Normally, if the CPU external 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
external clock.

When you change your CPU:

The PowerPro VX main board have been designed in such a way that you can turn
the system on after having inserted the CPU in the socket without configuring any
jumpers or DIP switches. But if you change your CPU, normally, you just need 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 three 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: 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.

Method 3: 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.

Chapter 3

20

CPU Power Plane:

In the previous chapter we explained that the 586 CPUs can be divided into two
types: single voltage and dual voltage. The system BIOS will normally auto-detect

the type of your CPU, and set the voltage accordingly, so you don’t need to make
any changes unless you want to configure the CPU with custom setting. You may skip

this section if your CPU is listed in the Soft MENU.

Single Voltage: Single voltage CPU
Dual Voltage: Dual voltage CPU
Set up the voltage via CPU Marking

 When the CPU is single voltage, the following options will be displayed to set

up the voltage:

Plane voltage:

3.52v For Intel VRE standard CPUs and AMK-K5 or Cyrix 8x86 CPUs

3.38v For Intel STD and VR standards CPUs

 When the CPU is dual voltage, two options will be displayed to set up Vcore

and Vio plane voltage

Core Plane Voltage:

2.90v For AMD-K6/200 CPU.

2.80v For Intel Pentium MMX, Cyrix 6x86L and Cyrix
6x86MX CPU.

2.70v For future CPUs.

2.50v For future CPUs. (If hardware supports.)

3.20v For AMD-K6/233 and future CPUs. (If hardware

supports.)

I/O Plane Voltage:

3.52v Reserved

3.38v Some CPUs from AMD need this I/O Plane Voltage.

3.30v For most of the dual voltage CPUs (default) currently available.

The CPU voltage must be set according to the manufacture’s specification. The

voltage information can be derived from the CPU Marking by the manufacturer. Since
the voltage of future CPU will decrease as technology improves, we have reserved some
options according to what we can forecast from present documentation. We cannot give
you detailed information about the voltage required by each kind of CPU in this chapter.
For the correct values, refer to appendices B, C and D.

 Set up the CPU voltage:
If you think that to set up CPU by referring Appendices is too complicated, you

may try to use the CPU Marking: within the options under “CPU Marking Is,”
set up the CPU by looking up the CPU Marking on the CPU.

Notes:

1. If your CPU is a dual voltage one and that the voltage set up is 3.52V, our
main board features a hardware protection circuit that will lower the voltage
between 2.8V and 2.9V, which is within the CPU operating voltage limits.

2. The voltage value given is the central value. For example, the voltage range
of 3.52V is 3.45V to 3.6V. The central voltage value between 3.45V and 3.6V
is 3.52V.

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. Doing so, the BIOS will not read the parameters

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

⚫ Set up of HDD operating mode: NORMAL, LBA, LARGE

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

Normal mode:

Standard normal mode supports hard disks of 528MB or less under
DOS. This mode directly uses positions indicated by Cylinders
(CYLS), Heads, and Sectors to access data.
Certain Operating System may require you to setup your IDE Hard
Disk in this mode.

System BIOS

23

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.

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.

 For further information about HDD installation, refer to Appendix E.

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.

System BIOS

25

CPU Internal Cache:

This item is used to Enable or to Disable the CPU internal 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 External Cache:

This item is used to enable or to disable the CPU external cache. When the external

cache is enabled, the system works faster. The default is Enable.

Quick power on self test:

After the computer has been powered on, the BIOS of the main board 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
 SCSI, C, A

A, SCSI, 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:.

Chapter 3

26

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:

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.

 For further details about hard disk drive installation, refer to appendix E.

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 certain rate. (Unit:

milliseconds)

System BIOS

27

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.

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.

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.

Chapter 3

28

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):

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.

SHADOW

The BIOS of standard video or other interface card is stored in ROM
on the card, which is often much slower than RAM. The VGA display
card usually use address B0000h to C7FFFh. With the Shadow
feature, the CPU reads the BIOS on the VGA card and copies it into
system RAM. When the CPU accesses the VGA BIOS for display, it
reads through RAM instead of ROM. Video shadow is often enabled
to speed up the display.

CHIPSET FEATURES SETUP MENU

The Chipset Features Setup Menu is used to modify the contents of the buffers in
the chipset on the main board. Since the parameters of the buffers are closely related to
hardware, if the setup is not correct or false, the main board 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.

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.

When you select Disable, you can manually set up DRAM options.

Chapter 3

30

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 autodetect

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 bloc 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 main
board 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.

System BIOS

31

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

Chapter 3

32

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.

Disable

Disable Power Management features.

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
Standby = 1 minute
Suspend = 1 minute

PM Control by APM:

Power Management is completely controlled by the APM.

APM stands for Advanced Power Mangement, 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”.

System BIOS

33

Video Off After:

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

Always On

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

All Modes Off

The video will be switched off in all 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, 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).

Chapter 3

34

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%, 75.0% or 87.5%.

CPU Fan Off In Suspend:

CPU fan can be turn off in suspend mode.

Reload Global Timer Events

When one of the speficied 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 speficied 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.

System BIOS

35

PCI & ONBOARD I/O SETUP

In this menu, you can change the PCI interrupt number (INTA, INTB,..) for the
PCI device and hardware interrupts (IRQs) available for PCI interrupts (INT#). You can
also change the onboard I/O device, I/O port address and other hardware settings.

Fig 3-6 PCI & Onboard I/O Setup

Reset PnP Configuration Data:

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.

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 Plug & Play
BIOS.

BIOS Auto-Config PCI IRQ:

This option enables or disables the BIOS capability to automatically assign IRQs.
The BIOS default is Disable.
When you select Enable, the BIOS will automatically assign the IRQ to the PCI
device in the PCI slots. When this option is disabled, you have to assign IRQs used
by the interrupt number (INT#) of the PCI slots.

Chapter 3

36

Xth Available IRQ:

You can select four IRQs out of the 10 listed (IRQ3, 4, 5, 7, 9, 10, 11, 12, 14, 15) to
be assigned for use by the PCI device in the PCI slot.

1st Available IRQ:

This means that the first PCI device found on the PCI bus will use this IRQ. That

is, this IRQ will be assigned to the PCI interrupt number (INT#) of the first PCI

device found on the PCI bus.

2nd Available IRQ:

This IRQ will be assigned to the PCI interrupt (INT#) of the second PCI device

found on the PCI bus.

The third and the fourth available IRQ will be assigned in sequence to PCI INT#

of the third and the fourth PCI devices found on the PCI bus.

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:

Since the main board has two IDE controllers on board, you rarely want to use an

add-on PCI IDE card. However, if you do, there are three options are available for

the PCI IDE card IRQ settings: 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 the same INT# twice.

System BIOS

37

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. Five options are

available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4 or 2E8h/IRQ3.

On board Serial Port 2:

This is used to specify the I/O address and IRQ of Serial Port 2. Five options are

available: Disable, 3F8h/IRQ4, 2F8h/IRQ3, 3E8h/IRQ4 or 2E8h/IRQ3.

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 EPP v.1.7, EPP v. 1.9, ECP, ECP+EPP 1.7, ECP+EPP 1.9 or
Normal (SPP) mode. Default is Normal (SPP) mode.

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.

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 PIO mode of the HDD in order to set

its data transfer rate. (Default)

Mode 0~Mode 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 PIO mode of the HDD in order to set

its data transfer rate. (Default)

Mode 0~Mode 4: User can specify the PIO mode of the HDD in order to

set its data transfer rate.

Chapter 3

38

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 PIO mode of the HDD installed in

order to set its data transfer rate. (Default)

Mode 0~Mode 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 PIO mode of the HDD installed in

order to set its data transfer rate. (Default)

Mode 0~Mode 4: User can specify the PIO mode of the HDD in order to

set its data transfer rate.

Note:

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.

 For further information about HDD installation, refer to Appendix E.

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.

Password setting procedure:

When you choose the Password setting option, the following message is

displayed:

“Confirm Password:“

Type your password again. When complete, press <Enter>. The password setting

is completed.

Password clearing procedure:

When you select the Password setting option, the following message is

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. But doing this, you must reset all your settings.

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 were
erased, and you had forgotten the hard disk specifications, it was a great problem. But
now, you can use this option to autodetect 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.

HDD Installation

Appendix E HDD Installation

Most of the present Hard Disk Drives (HDD) use IDE interface. Installing an IDE
hard disk is much easier than other type of hard drives. There are usually no software
driver to get it work for most operating system.

The data stored in the hard disk are accessed through a chipset located on the main
board. You probably 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
main board.

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 main board to the hard disk
drive, and than puts these data into the system memory.

What is the DMA mode? Usually, DMA mode refers to accessing the hard disk
data by the chip set, it does not refers to data transfer mode.

What is the Master mode? When the system needs to access hard disk data, these
data are directly accessed from the hard disk by the chipset on the main board (using a
DMA or a PIO mode), and then the data is put into the memory. In this case, the CPU
does not participate in the data transfer. The Master mode can reduce the CPU load,
especially in a Multi-task environment, and improve your system performance.

Here are some examples of data transfer rates for IDE HDD with PIO interface:

PIO Mode 0 The fastest data transfer rate reaches 3.3Mbyte/sec
PIO Mode 1 The fastest data transfer rate reaches 5.2Mbyte/sec
PIO Mode 2 The fastest data transfer rate reaches 8.3Mbyte/sec
PIO Mode 3 The fastest data transfer rate reaches 11.1Mbyte/sec
PIO Mode 4 The fastest data transfer rate reaches 16.6Mbyte/sec

The higher the MODE value is, the best is the hard disk data transfer rate. But this
does not mean that you can select the highest 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 examples of data transfer rates for IDE HDD with DMA mode:

DMA Mode 0 The fastest data transfer rate reaches 4.16Mbyte/sec
DMA Mode 1 The fastest data transfer rate reaches 13.3Mbyte/sec
DMA Mode 2 The fastest data transfer rate reaches 16.6Mbyte/sec

Installing a IDE Hard Disk or CD-ROM Drive:

In the Standard CMOS Setup Menu,

 Primary means the first IDE channel or port on the main board, that is,

connector IDE1 on our main board.

 Secondary means the second IDE channel or port on the main board, that

is, connector IDE2 on our main board.

 Two IDE devices can be connected to the each IDE channel:

One must be set to Single or Master. The other must be Slave.

IDE devices are connected through 40-pin ribbon cable. There are three
connectors on the cable. One end must be connected to the Main Board, the
other two can connect up to two IDE devices. The red line on the ribbon
cable must be lined up with pin 1 on the connectors. You must setup each
IDE device with proper jumpers unless you use special cable to select the
Mater or Slave. The bootable IDE Hard Drive is usually set to Master.
Please refer to the hard disk drive manual for the jumper setting.

Installing one HDD :

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 main board.

Installing one HDD + one CD-ROM drive:

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 main board.

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 main board.
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 main board.
We recommend you use this kind of connection, which has no
influence on HDD speed.

HDD Installation

E-3

Installing two HDDs

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 main board.

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 main board.
Set the other hard disk drive at Master, connect one end of the 40­pin cable to the drive, and the other end to connector IDE2 on the
main board.

Installing two HDDs + one CD-ROM drive:

Method 1: Set the IDE hard drive used for boot up to Master, set the other

HDD to Slave, and connect one connector at the end of the 40-pin
ribbon cable to the first drive, the middle connector to the second
drive, and the other end of the cable to connector IDE1 on the main
board.
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 the connector
IDE2 on the main board.
This method is recommended.

Method 2: Set the hard disk drive used for boot up to Master, connect one end

of the 40-pin cable to the drive, and the other end to connector
IDE1 on the main board.
Set the other hard disk drive to Master, and the CD-ROM drive to
Slave. After you have verified the Master/Slave settings, connect
one connector at the end of the 40-pin cable to the HDD, the
middle connector to the CD-ROM drive, and the other end of the
cable to connector IDE2 on the main board.

Installing three HDDs:

Method 1: Set the hard disk drive used for boot up to Master, set the second

drive to 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 main board.
Set the third drive to Master, and connect one end of the 40-pin
cable to the drive, and the other end to connector IDE2 on the main
board.

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 main board. Set the second drive to Master and the
third drive to Slave, connect one connector of the 40-pin cable to
the second drive, another connector to the third drive, and the other
end of the cable to connector IDE2 on the main board.

Installing three HDDs + one CD-ROM drive:

Set the hard disk drive used for boot up at Master, set another HDD (the
second) 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 main board.
Set the third hard disk drive at Master, set the CD-ROM drive at Slave,
connect one connector of the 40-pin cable to the third HDD, another connector
to the CD-ROM drive, and the other end of the cable to connector IDE2 on
the main board.

BIOS Setup:

Appendix E

E-4

 If all your HDDs are new, you can use the IDE HDD Auto Detection option

in the CMOS to autodetect the parameters of all your drives. You don’t need
to set any hard disk parameter.

HDD Installation

E-5

 If one or several of your HDD are old, and if you don’t want to erase the data

stored in your drives, you will have to manually enter the parameters (Type,
Cylinders, Heads, Sectors, Mode) of the drive(s) you don’t want to erase. After
you have used the IDE HDD Auto Detection option in the CMOS, enter the
Standard CMOS Setup Menu to change the settings of the related hard disk
drive.

Software use:

The basic step in using a hard disk drive is to make a HDD Low Level Format,
than run FDISK, and than FORMAT the drive. Most of present HDD have
already been subjected to low level format at the factory, so you probably can
skip this operation.

Boot with a bootable floppy disk, then enter FDISK.

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 before use. You can create one unique partition
on the hard disk, or create several partition and use a different Operating
System on each partition. Just don’t forget that you have to specify an Active
partition, 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 with FDISK, the system will reboot
automatically. Boot from a system floppy disk, and type FORMAT C:/S

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 formatted
before use. Don’t forget to add /S after C:, otherwise the hard disk will not
be bootable after formatting.

When you have a problem during operation...

In order to help our technical support personnel to quickly find out what is the problem
of your main board 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 this 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.)

Boot up problem

Example 1: With a system including: Main Board (with CPU and memory), 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 the system still do not boot up:

Try installing another brand/model VGA card and see if the system will
start. If it still does not start, check the power supply and try another
couple of times. If still does not boot, write down the VGA card model,
main board model, BIOS identification number, CPU on the technical
support form (refer to main instructions), and contact your vendor.

 If the system do boot up:

Insert the interface cards you have removed previously back into the
system 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 last add-on card that caused the problem and remove all other cards
or peripherals, and start again. If the system still does not boot, you may
have a hardware conflict. Write down the information related to both
cards in the add-on Card space provided, and don’t forget to indicate
the main board model, version, BIOS identification number, CPU (refer
to main instructions), and give a description of the problem. Contact the
hardware vendor for help.

System boots, but reset itself

Example 2: With a system including the Main Board (with CPU and memory) 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
or other memory resident programs (including virus). First get a bootable
floppy disk and try to clean boot. If it boot up normally, try to edit the
CONFIG.SYS and AUTOEXEC.BAT file for DOS. With a text editor, add
a remark REM in the front of the line that loads the driver, and reboot.
Using this trial and error method, you will eliminated most software errors.
