Introduction of
SM5/SM5-A Features
The SM5/SM5-A have been especially designed for File server,
Workstation and Professional users. It can support a wide range of processors,
including all Intel CPUs (P54C) and Intel CPUs with MMX (P55C), as well as
all AMD-K5 and Cyrix 6x86/6x86L CPUs. It also takes into account, as much as
possible, all future CPUs.
This series uses SOFT MENU™ technology, which means that all the
parameters can be configured without using DIP switches or jumpers. The
configuration is entirely achieved through a “Soft Switch” that allows the user to
set CPU speed and operating voltage with ease.
The SM5/SM5-A series uses Intel 430VX series chipsets, and has 256K or
512K Level-2 Pipeline Burst SRAM on board. It also provides an extension
slot allowing the user to upgrade Pipeline Burst SRAM to 512K.
Two 168-pin DIMM slots and four 72-pin SIMM slots meet the
requirements for all memory configurations required by high level computing.
The 168-pin DIMM slots support traditional Fast Page and EDO DRAM as a
memory standard for next generation 64-bit systems. The two 168-pin DIMM
slots have been reserved to meet requirements for both present and future
upgrades.
This series 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), as well as 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 (APM), the newest Desktop Management Interface (DMI), as well
as SM5/SM5-A’s unique CPU operating frequency and voltage setup feature in
order to meet modern computing demands.

Installing the Mainboard
This mainboard series not only provides all standard equipment for classic
personal computers, but also provides great flexibility for meeting future upgrade
demands. This chapter will introduce step by step all the standard equipment
and will also present, as completely as possible future upgrade capabilities. This
mainboard is able to support all Intel Pentium including P55C with MMX, Cyrix
6x86, 6x86L and AMD-K5 processors now on the market. (For details, see
specifications in Chapter 1.)
However, we cannot guarantee that the
description given in this manual on the circuitry of your mainboard will work for
processors not listed in Chapter 1. For example, the operating voltage of
Cyrix’s next generation CPUs is unknown at the present time. Thus we were
not able to include these specifications in your motherboard. We will supply
further information about CPU support when new CPUs arrive on the market.
This chapter is organized according the following features:
ΠStandard external connectors
• Jumpers and switches
Ž Installing the CPU--steps for installing Intel, Cyrix and AMD
processors.
• Installing cache memory--If you don’t want to upgrade the cache
memory you can skip this chapter.
• Installing the system memory.

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.

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

(SM5-A)
: Delete the contents of the CMOS
This jumper is set on pins 1 and 2 at the factory, in order for the
computer to function normally, so please do not change this setting.
The main feature of this jumper is to solve situations where the
computer crashes due to improper usage. For instance:
l You have forgotten the password you set.
l You have changed inappropriately the settings in the BIOS
menu.
l You want to change the version of flash BIOS.
All these errors are very serious, you must avoid them. But if you have
made one of these errors, this jumper can save your life. First turn off
the power supply and open the computer case, than place the jumper
on pins 2 and 3 in order to save your computer. But if you use your
computer normally, you should not need to use this feature.
After you have deleted the CMOS information, the computer is saved, but you
still have to go back to the BIOS Setup menu, and reset one by one all the
specifications: CPU, date, hour, FDD and HDD parameters. etc., before your
computer will get back into normal operation.
JP1 ¡G Installing the cache memory in the cache memory extension slot
(COAST) (the SM5-A do not support this feature)
On delivery, the SM5 mainboard comes with a 256K or 512K cache
memory. If you already have 512K, your mainboard will not need a
cache extension, and you will not be able to see the extension slot. But
if you have only 256K, we have reserved an extension slot which
permits you to extend the cache to 512K. This is set up at the factory
with no jumper, which is what we call OFF status. You will need to
put the jumper in place only when you extend the cache. For more
details, refer to the section which deals with cache memory.

® Presentation and Installation of the CPU
Jumperless Mainboard (Mainboard with no DIP Switch or Jumper)
The SM5/SM5-A mainboard can be installed with CPU without the
hardware setting of the CPU.
On other boards, when you want to install the CPU, you have, more or less,
to setup some jumpers or DIP switches. With this mainboard, you will not need
to adjust any jumper or switch. The CPU speed and model is set up by software,
in order to allow the user to complete setup and installation procedures easily.
After you have inserted the CPU on the CPU socket, you can close the computer
case and turn the computer on. You just need to enter the CPU SOFT MENU™
located in the BIOS Setup, and to setup the speed and the voltage of the CPU to
compete the installation. Even if you don’t need to setup any switch, we
recommend you to read our presentation of the CPUs, it will be useful
information for you.
Since 1996, every two or three months, Intel adds new models to the
Pentium CPU series. That is why the CPU market is filled with a lot of different
models and brands. All CPUs have different electrical specifications. That’s why
installing a CPU is becoming more and more complex. You can’t help that,
because everybody wants to be able to upgrade its hardware. So, you have to
take a bit of time to read this section, in order to be able to install a cheaper and
better processor.
This mainboard does not only support all the CPUs listed in the
specifications, but also has reserved several circuits in order to be able to support
future processors. But before we go further in our presentation, 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. But we will do our best to support any possible
CPU.
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.
2-12
Chapter 2
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 x 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.
The voltage of dual voltage CPUs has two components: Vcore and 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.
Installing the Mainboard
2-13
P-Rating
The P-Rating was defined by some 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, its internal clock needs only 133MHz versus 166MHz for
Intel’s product. The main reason is that Cyrix has improved the internal
architecture of the 6x86 CPU, which means that with the same internal
clock speed, the actual clock speed will be different.
Having read the related terminology above, please refer to the information in
appendices B, C or D for the type and specifications of your own CPU. We
suggest that you note down these specifications, which will help you when you
install the CPU.
CPU Settings:
¡I¡I CPU SOFT MENU ¡I¡I
To configure the speed and the voltage of the CPU, you must enter to the CPU

¯ Installing Pipeline Burst SRAM
The SM5 mainboard features a 256K or 512K cache memory. It also
features a cache memory extension socket (COAST) in order to permit you to
upgrade 256K cache to 512K, and this with only one JP1 to choose from.
Installation is very easy. Refer to the table below:

2. The configurations listed in the table are all the possible
configurations reserved when the board was designed. The actual
configuration when the board is delivered depends mainly on the
demands of the market.
3. The SM5-A mainboard do not support the cache extension slot
(COAST).
Installing the Mainboard

° Installing System Memory ¡i DRAM Memory ¡j
When this mainboard was designed, we not only have taken into account
the present needs, but we have also tried to care about demands for future
upgrades:
1. Two 168-pin DIMM sockets: (the SM5-A do not support this feature)
If you want to extend your memory capacity, you will have no solution
other than to use 168-pin 3.3V unbuffered DIMM sockets.
2. Four 72-pin SIMM sockets:
Currently, the most common memory modules on the market are 72-pin
SIMM modules. The four 72-pin SIMM sockets of this mainboard will
meet your needs.
3. Easy installation
You just need to insert the modules, without the help of God. Isn’t it
great?
Besides the features mentioned above, you can use simultaneously 72-pin SIMM
modules and 168-pin DIMM modules, but you will rarely encounter this kind of
configuration. Before you proceed with installation, be patient, first read what
follows:
1. Factory default setting of the mainboard is for 70ns FP or EDO
modules.
If your memory modules are faster than 70ns, say 60ns or 45ns, you can
modify the BIOS settings in order to speed up the operating speed of
the system. But if you don’t want to modify these settings, or if you
don’t know how to modify them, it’s no big deal.
But if you set the external CPU clock at 66MHz or more, we
recommend you use 60ns or even faster DRAM modules.
2. Memory error check and correction do not support this feature on
this mainboard.
Since the Intel 430VX chipset 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 feature, this mainboard does not support it.
3. Maximum memory capacity 128M Bytes supported by this
mainboard.

¡i Relationships between memory modules and Pentium
CPUs ¡j
Pentium, 6x86 and AMD-K5 are all 64 bit CPUs, but 72-pin
SIMM modules are only 32-bit. That’s why they have to be used
in pairs, because the CPU will always be only able to see 64 bits.
This means that 72-pin SIMM modules have to be installed in
pairs. For instance, SIMM1 and SIMM2 must form a pair, and
SIMM3 and SIMM4 must form another pair. Of course, the two
members of a pair must be of the same kind ¡i EDO or FP
DRAM ¡j, and you cannot use pairs from different “species”.
But the SM5/SM5-A support different “pairs” and use different
type of memory modules, notice:
l ¡i SIMM1 and SIMM2 ¡j must use the same memory
type, as well as ¡i SIMM3 and SIMM4 ¡j.
l ¡i SIMM1 and SIMM2 ¡j use the same memory type, and
¡i SIMM3 and SIMM4 ¡j can use the same type, or a
different type, in order to permit you to obtain the best
speed configuration for each “single” pair, and to make
the system work at its maximum capacity. If one
memory pair is slower, it will have no influence on the
pair whose speed is higher.
168-pin DIMM modules are 64 bit, so you can use single modules.
On the SM5 mainboard, these modules can support not only EDO
and FR DRAM, but also Synchronous DRAM memory
configurations. The SM5-A mainboard does not support
SDRAM.
When you install DIMM modules on the mainboard, you don’t have to setup
anything, just be sure that you use 3.3V unbuffered 168-pin DIMM modules, and
insert them in the memory socket.
Computer
Knowledge
¡i 168-pin DIMM modules specifications ¡j
According to the standards defined by JEDEC, there are a lot of
different types of specifications for 168-pin DIMM sockets. Here
are the possible types:
l 3.3V UNBUFFERED DIMM
Installing the Mainboard
2-17
l 3.3V BUFFERED DIMM
l 5V UNBUFFERED DIMM
l 5V BUFFERED DIMM
These types of DIMM modules differ not only by the electrical
design, but also by their architecture. So, if you buy different
types of DIMM modules, you will not be able to insert them in the
DIMM sockets. Currently, the standard for PC is 3.3V
UNBUFFERED DIMM, which is the standard supported by this

After installing the DRAM, the BIOS of the mainboard will automatically detect
the size of the memory installed on the mainboard. Below is a list of all the
possible situations:
Scenario 1: You use only 72-pin SIMM modules:
l The maximum memory size is 128M bytes.
l Support possible for single density or double density memory
modules.
l Memory modules supported: 1Mx32 ¡i 4M ¡j, 2Mx32
¡i 8M ¡j, 4Mx32 ¡i 16M ¡j or 8Mx32 ¡i 32M ¡j.
l ¡i SIMM1 and SIMM2 ¡j is the first pair, ¡i SIMM3 and
SIMM4 ¡j is the second pair. Usually, you first insert the first
pair, than the second pair, but it is possible to do the reverse.
l You can also directly refer to table 2-1.
Scenario 2: You use only 168-pin DIMM modules: (the SM5-A do not support
this feature)
l The maximum memory size is 128M bytes.
l Support possible for single density or double density memory
modules.
l Memory modules supported: 1Mx64 ¡i 8M ¡j, 2Mx64
¡i 16M ¡j or 4Mx64 ¡i 32M ¡j.
l DIMM1 is the first pair, DIMM2 is the second pair. Usually,
you first insert modules in DIMM1 socket, than in DIMM2
socket, but it is possible to do the reverse.
l You can also directly refer to table 2-2.
Scenario 3: You use 72-pin SIMM modules and 168-pin DIMM modules: (the
SM5-A do not support this feature)
l The maximum memory size is: 128M Bytes.

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 voltage and 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, configures
the parameters of the hardware synchronization, and detects all the hardware.
Only when these tasks are completed does it give up control of the computer to
the program of the next level, which is the operating system. Since the BIOS is
the only channel for hardware and software to communicate, it will be the key
factor to system stability, and to ensure that your system performs at its best.
After the BIOS has achieved the auto-diagnostic and auto-detection operations,
it will display the following message:
TO ENTER SETUP BEFORE BOOT PRESS CTRL-ALT-ESC OR DEL KEY
3-2
Chapter 3
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 menu. At that moment, the BIOS will display the following message:

knowledge
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 indoing 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
3-5
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.
ä Disable: CPU external clock is operating within the
normal limits.
ä Enable: CPU external clock is operating within the limts
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 SM5/SM5-A mainboards have been designed in such a way that you
can turn the system on after having inserted the CPU in the socket without
having to configure any jumpers or DIP switches. But if you change your CPU,
normally, you just have to turn off the power supply, change the CPU and then,
set up the CPU parameters through CPU SOFT MENU™ . 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.
3-6
Chapter 3
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 JP3(SM5)/JP1(SM5-A)
jumper to erase the parameters of the original CPU and to enter
BIOS Setup to set up CPU parameters again.
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.
CPU Power Plane:
In the previous chapter we explained that the 586 CPUs can be divided into
two types: single voltage and dual voltage. This option will normally auto-detect
the type of your CPU, so you don’t need to make any changes.
ä Single Voltage: Single voltage CPU
ä Dual Voltage: Dual voltage CPU
ä 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:
ä 3.52v ¡G For Intel VRE standard CPUs and AMK-K5 or Cyrix 8x86
CPUs
ä 3.38v ¡G For Intel STD and VR standards CPUs
Introduction of BIOS
3-7
¤ When the CPU is dual voltage, two options will be displayed to set up
Vcore and Vio plane voltage
/ Core Plane Voltage:
ä 2.90v ¡G For AMD K6-200 CPU.
ä 2.80v ¡G For Intel Pentium MMX and Cyrix 6x86L CPU.
ä 2.70v ¡G For future CPUs.
ä 2.50v ¡G For future CPUs. (If hardware supports.)
ä 3.20v ¡G For AMD K6-233 and future CPUs. (If hardware
supports.)
/ I/O Plane Voltage:
ä 3.52v ¡G Reserved
ä 3.38v ¡G Some CPUs from AMD need this I/O Plane Voltage.
ä 3.30v ¡G For most of the dual voltage CPUs (default) currently
available.
The CPU voltage must be set according to voltage indications via CPU
Marking given by the manufacturer. Since the CPU voltage 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 voltage via CPU Marking:
If you consider using the Appendices to set up as too complicated, you
can use the CPU Marking: within the options under “CPU Marking Is,”
set up via 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 mainboard 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.
3-8
Chapter 3
Attention: After setting up the parameters and you leave the BIOS SETUP, and
you have verified that the system can be turned on, 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.

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.
3-10
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.

Chapter 3
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 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:
ΠA, C, SCSI
• C, A, SCSI
Ž 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
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
3-13
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 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)
Security Option:
3-14
Chapter 3
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.
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
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).

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 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

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
Disable
Disable Power Management features.
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 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”.
Introduction of BIOS
3-21
Video Off Option:
Select the saving mode in which the video is switched off.
ä
Always On
The video will never be switched off in no saving mode.
ä
All Modes Off
The video will be switched off in all saving modes.
ä
Suspend or Suspend (Susp,Stby --> Off)
The video will only be switched off in Standby or Suspend mode.
ä
Suspend (Suspend --> Off)
The video will only be switched off in Suspend mode.
Modem Use IRQ:
If you use a modem, enter which IRQ it is using so that the APM can control
it.
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).
3-22
Chapter 3
Standby Mode:
When the setting selected for "Power Management" is "User Define", you
can define for this mode any delay from 1 minute to 1 hour. If no power
management event occurs during this time period, meaning the computer is
inactive during this period, the system will enter the Standby power saving
mode.
If this mode is disabled, the system will enter the next mode in the sequence
(Suspend mode).
Suspend Mode:
When the setting selected for "Power Management" is "User Define", you
can define for this mode any delay from 1 minute to 1 hour. If no power
management event occurs during this time period, meaning the computer is
inactive during this period, the system will enter the Suspend power saving
mode. The CPU stops working completely.
If this mode is disabled, the system will not enter the Suspend mode.
Wake-Up Events:
When system is in Doze or Standby power saving mode, it will check for the
wake-up events (IRQ4, 3, 8, 12) defined. When it detects an activity of one
of the IRQs defined, it exits the power saving mode and returns to full
operation mode (Normal).
Wake-up events are all operations or signals that cause the system to
recover normal operation.
Power Down & Resume Events:
When one of the power down and resume events (IRQ3-15) 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.

Computer
Knowledge
ESCD (Extended System Configuration Data)
The ESCD contains the IRQ, DMA, I/O Port, Memory data of
all PnP cards, PCI cards and Onboard I/O. This is a specification
and a feature specific to Plug & Play BIOS.

Chapter 3
PCI PnP BIOS Auto-Config:
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 correct IRQ
to the interrupt number (INT#) of the PCI slots. When this option is disabled,
you have to assign IRQs used by the interrupt number (INT#) of the PCI
slots.
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 interrupt number (INT#) of the PCI slot.
1st Available IRQ:
This means that the first interrupt number (INT#) found on the PCI bus will
use this IRQ. That is, this IRQ will be assigned to the first interrupt number
(INT#) found on the PCI bus.
2nd Available IRQ:
This means that the second interrupt number (INT#) found on the PCI bus
will use this IRQ. That is, this IRQ will be assigned to the second interrupt
number (INT#) found on the PCI bus.
The third and the fourth available IRQ will be assigned in sequence to
the third and the fourth interrupt numbers (INT#) 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:
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.
Introduction of BIOS
3-25
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#).
Note:
Since the interrupt number of the PCI slot is connected according
the design described below, there are some limitations, be careful.
+ The INT#A signal of the first PCI slot, the INT#B signal of the
second PCI slot, the INT#C signal of the third PCI slot and the
INT#D signal of the fourth PCI slot, are the same, so be careful
not to use them simultaneously.
+ The INT#B signal of the first PCI slot, the INT#C signal of the
second PCI slot, the INT#D signal of the third PCI slot and the
INT#A signal of the fourth PCI slot, are the same, so be careful
not to use them simultaneously.
+ The INT#C signal of the first PCI slot, the INT#D signal of the
second PCI slot, the INT#A signal of the third PCI slot and the
INT#B signal of the fourth PCI slot, are the same, so be careful
not to use them simultaneously.
+ The INT#D signal of the first PCI slot, the INT#A signal of the
second PCI slot, the INT#B signal of the third PCI slot and the
INT#C signal of the fourth PCI slot, are the same, so be careful
not to use them simultaneously.
On Board USB Controller:
This is to Enable or Disable the onboard Universal Serial Bus (USB)
controller.
Onboard PS/2 Mouse:
This is to Enable or Disable the PS/2 Mouse. When in Enable, IRQ 12 is
used.
3-26
Chapter 3
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.
Attention:Do not select the same I/O address and IRQ for the two serial
ports, otherwise the serial ports will not be able to operate
normally.
/ Onboard IR Function:
Onboard serial port 2 can support IR (Infrared) function. Three
options are available:
ä Disable: No support for IR function.
ä IrDA (HPSIR) mode.
ä ASK IR (Amplitude Shift Keyed IR) mode.
/ IR Duplex Mode:
Set the IR mode as Half or Full. Default is Half.
/ IR Tr/Re Polarity:
Set IR transmission/reception polarity as High or Low.
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.

Computer
knowledge
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.

µ 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.

General Discussion about HDD Installation

Appendix E General Discussion about
HDD Installation
Most of the present HDDs use IDE interface. Installing an IDE hard disk
does not require a huge amount of intelligence 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 possible problems.
The data stored in the hard disk are accessed through a chipset located on
the mainboard. 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 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 than puts these data into the system memory. This is the
PIO 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
mainboard (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.
What is the DMA mode? Usually, DMA mode refers to accessing the hard
disk data by the chipset, it does not refers to data transfer mode.
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
E-2
Appendix E
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
Usually, PIO mode means that the hard disk data are accessed by the CPU
through the chipset and placed into memory, and the chipset is using PIO mode
to access hard disk data.
MASTER mode means that hard disk data are accessed by the chipset, and
that the chipset places the data into memory. The chipset 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
performance.

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.
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.
E-4
Appendix E
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 another
drive (the second drive) at Master and the third drive at
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 mainboard.
Installing three HDDs + one CD-ROM drive: The red line on the connection cable must be lined
up with pin 1 on the connector.
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 mainboard.
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 mainboard.
BIOS Setup:
♦ 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.
♦ If one or several of your HDDs are old, and if you don’t know their
parameters, and you want to reconfigure your drives, you can also use
the IDE HDD Auto Detection option in the CMOS to autodetect the
drives parameters.
E-6
Appendix E
♦ 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 remember 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.

Appendix F Technical Support
L 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 mainboard and to give you the answers you need, before filling
in the technical support form, eliminate any peripheral that is not related to the
problem, and indicate on the form the key peripherals. Fax 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.)

Example 1: With a system including: mainboard (with CPU, DRAM, COAST...)
HDD, CD-ROM, FDD, VGA CARD, MPEG CARD, SCSI CARD,
SOUND CARD..., after the system is assembled, if you cannot boot
up, check the key components of the system using the procedure
described below.
First remove all interface cards except the VGA card and try to
reboot.
F If you still cannot boot up:
Try installing another brand/model VGA card and see if the
system will start. If it still does not start, note the VGA card
model, mainboard model, Bios identification number, CPU on
the technical support form (refer to main instructions), and
describe the problem in the problem description space provided.
F If you can boot up:
Insert back the interface cards you have removed one by one and
try to start the system each time you insert a card, until the
system doesn’t start anymore. Keep the VGA card and the
interface card that causes the problem inserted on the mainboard,
remove any other card or peripheral, and start again. If you still
cannot start, note down the information related to both cards in
the Add-On Card space provided, and don’t forget to indicate
the mainboard model, version, BIOS identification number, CPU
(refer to main instructions), and give a description of the
problem.

Example 2: With a system including the mainboard (with CPU, DRAM,
COAST...) HDD, CD-ROM, FDD, VGA CARD, LAN CARD,
MPEG CARD, SCSI CARD, SOUND CARD, after assembly and
after having installed the Sound Card Driver, when you restart the
system, when it runs the Sound Card Driver, it resets automatically.
This problem may be due to the Sound Card Driver. During the
Starting DOS… procedure, press SHIFT (BY-PASS) key, to skip
CONFIG.SYS and AUTOEXEC.BAT; edit CONFIG.SYS with a
text editor, and in front on the line that loads the Sound Card Driver,
add a remark REM, in order to disable the Sound Card Driver. See
the example below.
CONFIG.SYS:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE HIGHSCAN
DOS=HIGH,UMB
FILES=40
BUFFERS=36
REM DEVICEHIGH=C:\PLUGPLAY\DWCFGMG.SYS
LASTDRIVE=Z
Restart the system. If the system starts and does not reset, you can
be sure that the problem is due to the Sound Card Driver. Note
down the Sound Card model, mainboard model, BIOS identification
number on the technical support file (refer to main instructions), and
describe the problem in the space provided.
