Component Information

This section is a brief description of the components on the

mainboard that you might need to know about if you want to
upgrade or change your system configuration. If your mainboard
is already installed in a system, it isn’t necessary for you to re­view this section.

This mainboard uses a Baby-A T ‘form factor’, in a design that

integrates many features onto the board including some number
of external port connectors.

Expansion Cards & Slots

The mainboard has seven expansion slots for system expan-

sion or ‘add-on’ cards. Three of them are ISA slots, three are PCI
slots and one is an AGP (Accelerated Graphics Port) slot. When
you get an expansion card, it must use one of these to connect to
the computer.

The ISA expansion slots are a legacy of the original IBM PC/

A T design. They are 16-bit slots that run at a moderate bus speed.
There are many kinds of expansion cards that use this slot design
to connect to the computer, some of the most common being
sound and modem cards.

PCI slots are the current high-speed 32-bit standard for sys-

tem expansion cards. They operate at a faster speed and have a
greater data throughput than ISA cards.

The AGP Slot is a specialized slot that is only for AGP inter-

face display cards. It provides a high speed interface for the dis­play card and is particularly designed to enhance 3D performance.

Expansion cards often make use of system resources, which

requires managing the system resource configuration. Most newer
expansion cards support the ‘Plug and Play’ standard that allows
an Operating System like Windows95 to automatically detect
them and configure system resources as needed. Some older ISA
designs may not support this standard and may therefore require
manual configuration. You should consult the specifications or
documentation for a card to determine if this is the case and what
needs do be done to properly configure the card.

1: Package & Product Information – 1.7

Memory Sockets & Modules

There are six memory module sockets on the mainboard. T wo
are for 168-pin DIMM memory modules. The DIMM sockets
function independently of each other . The other four sockets are
for 72-pin SIMM memory modules. The SIMM sockets are paired
into two ‘banks.’ This means you must install two modules at a
time to fill one bank. You cannot use DIMM and SIMM modules
at the same time on this mainboard.

This mainboard has a very flexible memory design that al­lows the use of a variety of memory options up to a total of
384MB. There is more information about this in Adding System
Memory section of Section 3: Reconfiguring Your Mainboard.

CPU Socket & CPU

The Socket 7 CPU socket supports the full range of Pentium®­class CPUs including MMX Pentiums
socket is easy . The lever at the side of the socket latches the CPU
in place when it is down and releases it when raised.

If you want to install a CPU upgrade or are installing a CPU
on the board for the first time, please refer to ‘Installing a CPU’ in
Section 3: Reconfiguring Your Mainboard.

®

. Installing a CPU in the

Port & Controller Connections

There are several ports and connectors on the mainboard. Some
are external ports and others are internal connectors that connect
to other parts of the computer or internal options.

External Ports

This mainboard has several external ports including the COM1
and COM2 serial ports, a Parallel port, dual USB ports and PS/2­type keyboard and mouse ports. All but the keyboard and mouse
ports use external port brackets which mount in expansion card
slot openings and attach to connectors on the mainboard. These
external ports are all accessible at the rear of the computer when
the mainboard is installed.

CMOS Setup Utility Controls

T wo sections of the CMOS Setup Utility allow you to config­ure how some of your system’s features work. These are:

• BIOS Features Setup

• Power Management Setup

The CMOS Setup Utility is a program that is permanently
stored in the BIOS chip on the mainboard. The utility creates a
system hardware configuration record that it stores in a small
amount of battery-supported memory on the board. The BIOS
uses this record to function as an interface between the system
hardware and the operating system. Most of the settings in the
CMOS Setup Utility are made automatically, so you won’t nor­mally need to use this program. You can, however, customize
some of the operational features to suit how you prefer to use
the system.

The screen illustrations on the next two pages show the Setup
Default settings for these two sections of the utility.

Cooling Fan Connectors

There are two cooling fan power connectors on the mainboard.

One is for the CPU cooling fan (CPUFAN1) and the other for a
case-mounted cooling fan (SYSFAN1). When the system enters
Suspend mode, the cooling fans shut off.

UltraDMA Hard Disk Drive Support

This mainboard supports hard disks that use UltraDMA data

transfer. You attach an UltraDMA drive to one of the IDE cables.
If you use the Optimum Settings feature in the CMOS Setup
utility the system will automatically detect the drive and config­ure the system to use it.

CMOS Support Battery

The disk shaped battery on the mainboard is a 3-volt Lithium

cell battery that supports the small amount of onboard memory
where the CMOS Setup utility’s configuration record is stored.
The battery will last for a number of years and can conceivably
outlast the usage period of the computer it is in.

If the battery fails, the system will not retain the CMOS Setup

configuration and the system will need to be reconfigured every
time you turn it on. If this happens, replace the battery with the
same type as is installed. You can get a replacement at many
electronics supply stores, computer stores and other places that
sell a variety of batteries for various uses.

P5SD-B User’s Manual

2: Using Your Mainboard – 2.9

Optional Hardware Connectors

There are additional feature connectors on the mainboard for

optional ports. These require optional external port hardware.

IR Ports

There is one standard and one optional connector on the main­board which support an IR (infrared) port module that enables
wireless communication between the computer and other com­puters and devices with an infrared port. The default IR connec­tor, SIR, is for Intel IR compatible modules and the optional FIR
connector is for a Fast IR module.

The port module is an optional component. If it is installed,
you must set the UART 2 line in the Integrated Peripherals sec­tion of the CMOS Setup utility to the appropriate IR mode used
by the module.

P5SD-B User’s Manual

2: Using Your Mainboard – 2.10

Firmware & Software

The mainboard hardware is supported by both firmware and

software components. Firmware is software that is stored on a
chip on the board rather than on disk media.

The firmware component you interface with on this main-

board is the CMOS Setup Utility. This utility establishes various
settings used by the BIOS, the basic software that is an interface
between the system hardware and software.

The software component is comprised of software drivers that

support the PCI IDE controller and some of the other hardware
features.

How To Use The CMOS Setup Utility

The CMOS Setup Utility options are listed in detail in Section

4: Reference Information. This section is just a brief explanation
of how to run the program to adjust settings as noted in this and
the next section.

To run the CMOS Setup Utility, press the Del or Delete key

while the computer is starting up, before the operating starts to
load. The utility’s main screen will appear as shown on the next
page. To navigate the program, use the controls shown on the
screen. The utility has several sections. Many of the features con­figured by the utility are set to operate automatically when the
‘Setup Defaults’, the recommended mode, are used. With Setup
Defaults loaded you can still customize various settings.

Clearing CMOS

Under some unusual circumstances the configuration record

created by the CMOS Setup utility and stored on the mainboard
can become corrupted and unusable, possibly leading to the board
being unable to operate properly. If this happens, the CMOS
record can be cleared by setting jumper JP6 to the clear setting for
a moment and then setting it back to the Normal setting. Refer to
Section 4 for more information.

Flashing The BIOS

This mainboard uses the Award BIOS. The BIOS is stored on

a programmable flash memory chip on the mainboard. Updates
to the BIOS can be installed by installing a new BIOS file on the
flash chip, which replaces the existing one. You do this using
software that comes on the Support Disk. There is an explana­tion of how to install a BIOS update in a ‘readme’ text file in­cluded with the program.

Bus Master Drivers

This mainboard comes with software drivers, for various Op-

erating Systems, that enable the PCI controller to operate in ‘Bus
Master’ mode. The drivers are on the Support Disk. The included
‘readme’ file has information on the drivers and installation in­formation.

AGP Drivers

T o use an AGP display card with this mainboard you need to

install some support software first. The necessary software is sup­plied with the mainboard and is stored on the Support Disk.

To use an AGP display card with this mainboard you must

use either Windows 95 version OSR2.1 or Windows 98. If you
are running OSR2 you must upgrade to version 2.1 by installing
the upgrade available from Microsoft on their website. The re­quired upgrade file is titled USBSUPP.EXE and also installs sup­port for USB devices under Windows 95.

To check which version of OSR2 you are running, you must

check in the Windows registry and find the subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

The version number shown must be either 4.03.1212 or

4.03.1214. Anything earlier than version 1212 must be upgraded
using the USBSUPP.EXE upgrade. If you are unsure of how to
check in the registry, you can install the upgrade to ensure the
necessary files are installed.

In addition to the above, you must also have DirectX version

5.0 (build 122 or later) installed. Earlier versions of DirectX do
not support AGP.

P5SD-B User’s Manual

2: Using Your Mainboard – 2.13

SiS AGP Support Files

The mainboard ships with AGP support files for the board’s
chipset (SiS 5591) for the supported versions of Windows 95 and
for Windows 98. The Windows 95 AGP support file is named SiS
SISGART.VxD. The file for Windows 98 is a miniport driver for
the 5591 chipset. It is named SISPCIMP.PCI. The files are stored
in a SiS 5591 GART VxD directory on the Support Disk. The
SETUP.EXE file in the directory is an auto-installation file that
installs the proper file for the Operating System it detects.

Installation Procedure

You must follow a specific order when installing the support
software for this mainboard if you intend to use the AGP feature.
After ensuring that you have a compatible version of Microsft
Windows and DirectX installed, you must install the SiS IDE Bus
Master driver and the Display driver for the AGP card before you
install the appropriate SiS AGP support file. The installation pro­cedure should be as follows:

1. Make sure a compatible Operating System is installed, or up-

grade as necessary.

2. Install the supplied SiS IDE Bus Master Driver for Windows

95 and without restarting install the Display driver supplied by

your AGP display card manufacturer for the AGP card you

have installed in the system. DO NOT restart the system yet.

3. Run the SETUP.EXE file in the SiS 5591 GART VxD directory

on the Support Disk to automatically install the appropriate

AGP file for your Operating System (either SiS SISGART .VxD

for Windows 95 or SISPCIMP.PCI for Windows 98.)

4. Restart the computer to complete the installation.

In This Section:

Installing Expansion Cards
Adding System Memory
Installing A CPU Upgrade
Adding An IDE Peripheral

3: Reconfiguring Your Mainboard

This section explains how to install new hardware on your
mainboard. It covers installing expansion cards, adding system
memory , changing the CPU and installing additional IDE periph­eral devices such as a hard disk or a CD-ROM drive.

Installing Expansion Cards

There are seven expansion card slots on the mainboard, three
ISA slots and thre PCI slots and one AGP slot. Expansion cards
will come with installation instructions, so this section covers
relevant information from the mainboard side only.

ISA Cards & Slots

ISA expansion cards often use system resources in the form of
IRQs and DMA channels. Newer cards that comply with the Plug
and Play (PnP) standard are designed to allow the Operating Sys­tem (OS) to automatically configure system resources. Cards that
do not support PnP may require manual configuration of both
the card hardware and settings in the CMOS Setup Utility. This
may also be the case if you are using a non-PnP OS.

If you have a PnP-compliant card to install there should be
little to do other than follow the installation instructions. If, how­ever, you have a non-PnP car d and it requires configuring system
resources, you may need to review the third part of this section,
Configuring Expansion Card Resources In CMOS Setup.

P5SD-B User’s Manual

3: Reconfiguring Your Mainboard – 3.2

PCI Cards & Slots

With very few exceptions, any PCI expansion card you are

likely to get will be Plug an Play compliant. If you are using an
Operating System that supports PnP, such as Windows 95, you
should be able to follow the installation instructions that come
with the card and have the Operating System automatically rec­ognize and configure the card.

The four PCI slots on the mainboard all have ‘Bus Master’

capability. For installed PCI cards to use this feature an Operat­ing System-specific Bus Master software driver that comes with
this mainboard must be installed under your Operating System.
These drivers are located on the Support Disk. There is more
information about them later in this section.

The AGP Slot

This mainboard has one other expansion slot, the AGP or Ac-

celerated Graphics Port slot.

The AGP slot is a high-speed slot for a display card that uses

the AGP interface. The AGP design maximizes the performance
of the display card, especially for 3D operations, by providing a
high-speed interface and access to system memory for 3D ren­dering. AGP offers a substantial performance enhancement when
compared to an equivalent display card with a PCI interface.

You set the amount of system memory available to the AGP

card in the CMOS Setup Utility’s ChipSet Features Setup section
under AGP Aperture Size.

4: Reference Information, has a section called PNP/PCI Configu­ration. The default settings in this section allow the Operating
System to automatically configure IRQ resources for PnP com­pliant ISA and PCI Cards.

If you need to install a non-PnP card, you will need to config-

ure any IRQ and DMA settings manually, both on the card and
in the CMOS Setup Utility . The following three pages show how
to do this.

CMOS Setup Utility –

PnP/PCI Configuration
This is the default screen for
this section when Setup De­faults are loaded. If you need
to manually configure the IRQ
settings, set the first item on
the screen to the ‘Manual’
setting. See the next page.

If you install an Operating Sys­tem that supports Plug and
Play, such as Windows95,
you should set the first line,
‘PNP OS Installed’ to ‘Yes’.

Running CMOS Setup

To run the CMOS Setup utility,
press the Delete or the Del
key while your computer is
first starting up. Select the
‘PNP/PCI CONFIGURATION’
item on the main screen and
press the Enter key to open it.

When you are finished, press
the Esc key once to return to
the main screen and then se­lect ‘SAVE & EXIT SETUP’ and
press the Enter key to save the
new configuration. For more
information on this see Sec­tion 4: Reference Information.

CMOS Setup Utility –

PnP/PCI Configuration
When ‘Resources Controlled
By’ is set to ‘Manual’ you can
individually configure the IRQ
& DMA channel settings. The
individual defaults are for PnP
cards and will still use all the
items listed to automatically
assign resources as needed.
If you are installing a ‘legacy’
ISA card that requires manual
configuration, you can manu­ally assign the required re­sources as needed.

This screen shows an ex­ample of a manually config­ured IRQ setting for a “Legacy’
ISA expansion card. Legacy
cards, by definition, are not
PnP compliant and must be
manually configured if they
require an IRQ or DMA chan­nel. See the card manual for
specifics.
When an item in the list is con­figured this way, it is no longer
part of the pool of automati­cally configurable resources.
For this reason, don’t config­ure ISA cards this way unless
they are Legacy cards.

Adding System Memory

There are some requirements you must follow if you want to
install system memory . The memory subsystem has four 72-pin
SIMM sockets divided into two banks, SIMM1 & SIMM2 and
SIMM3 & SIMM4. It also has two DIMM sockets. You cannot
use SIMMs and DIMMs at the same time on this mainboard.

SIMM modules should use either Fast Page Mode (FPM) or
EDO 5-Volt DRAM. You can use modules from 4MB to 128MB,
either single or double-sided. DIMM modules must use 3.3-Volt
unbuffered EDO or SDRAM. Total supported memor y capacity
is 384MB.

If your mainboard is already installed in a system, it will have
some amount of memory installed on the board. You can tell
how much by checking the configuration screen that appears
when the computer is starting up. With some memory installed,
there may be sockets available to add additional memory. If not,
you must remove modules to install an upgrade.

N

D

You can not use SIMM and
DIMM modules at the same
time on this mainboard.

It is possible to install more
memory than the board sup­ports, e.g. four 128MB SIMM
modules would total 512MB,
but the board would ignore
128MB of that. Do not install
more than 384MB on this
mainboard.

P5SD-B User’s Manual

3: Reconfiguring Your Mainboard – 3.6

Memory Configurations

SIMMs install in pairs. You can install any SIMM memory

combination as long as you follow the basic requirement of in­stalling identical modules in both sockets of a bank, i.e.:

• 5-Volt modules

• Both modules are the same size, e.g. 16MB (MegaBytes)

• Both are the same DRAM memory type, e.g. EDO

• Both use the same operating speed, e.g. 60ns (nanoseconds)
Each DIMM is a memory Bank. You can install DIMMs with

these specifications:

• 8MB to 128 MB single or double-sided modules

• 3.3-Volt unbuffered EDO or SDRAM DRAM modules only
Other than these requirements, there is no limitation on the

variety of possible combinations, so they are not listed here.

Memory Sockets

The picture at right shows the
memory module sockets.
Modules press into place and
are held in position by a re­taining clamp at each end of
the socket.
When you want to remove a
module, press down on the
retaining clamps to push the
module out of the socket.

The SIMM sockets are num­bered SIMM1 to SIMM4 as
noted. You must install mod­ules in pairs in either sockets
1 & 2 or 3 & 4.
Modules snap into place and
are held in position by a re­taining clip at each end of the
SIMM socket.
When you want to remove a
module, press down on the
retaining clips to release the
module from the socket.

Installing Memory Modules

Modules are designed so that they will only insert in one ori-

entation. If you have trouble inserting the connector edge of a
module into a socket, it may be oriented the wrong way. Turn
the module around and try again. You shouldn’t need to force it.

To install a SIMM module, insert it into the socket at about a

45° angle and then push it up into the retaining clips so that it
snaps in place and is at a 90° angle to the board.

To install a DIMM module, look at the module and note the

position of the shorter section of the connector edge that plugs
into the DIMM socket. Note the position of the shorter section
of the socket. Orient the module so that these match and press
the module into the socket at a 90° angle. The retaining clamps at
each end of the socket will rotate upwards automatically.

If All Sockets Are Occupied

If you want to install more memory and there are no sockets

available, you must remove some installed modules and replace
them with upgrade modules.

If you have to do this, make sure to identify what type of

memory is already installed. In some cases, there may be a mix
of module types. You can tell this by checking the configuration
screen that appears while the computer is starting up.

Remove the lowest performance and smallest size modules

and replace them with the upgrade. EDO is faster than Fast Page
and SDRAM is faster than EDO. For example, if you have the
following configuration and you plan to install two 32MB EDO
SIMM modules:

• SIMM 1 & 2: 8MB Fast Page mode modules

• SIMM 3 & 4: 16MB EDO modules
You should remove the two 8MB FP modules because they

are lower performance and replace them with the memory up­grade, resulting in the greatest performance gain.

Installing A CPU Upgrade

If you are installing this mainboard it will not have a CPU
installed unless your vendor installed one when you purchased
the board. If the mainboard is installed in a system, there will
already be a CPU installed. In either case the information and
procedure for installing a CPU is the same. Since the more likely
scenario is that you are installing an upgrade, this section assumes
that is what you are doing.

The Basic Procedure

To install a CPU on this mainboard you need to set up the
board for a specific CPU by doing the following:

• Set the External Clock Speed

• Set the Clock Multiplier Factor

• Set the CPU Voltage

You configure the CPU settings by adjusting jumper settings
on the board. In order to do this, you will need to know some
information about the CPU you plan to install. This should be
provided by the CPU vendor or by the vendor you buy the chip
from. You’ll need the following information:

• CPU Internal Clock Speed

• CPU Voltage

The internal clock speed is the speed the CPU operates at to
process data and is the one used by CPU manufacturers to indi­cate the speed of the chip, for example, a 233MHz Intel Pentium
The CPU also has an external clock speed which is the speed at
which it interacts with external components.

CPU voltage may either be the same internally and externally
or it may be split, depending on the CPU design. Some proces­sors use one voltage for the ‘core’ (Vcore) and another for input/
output (Vio).

P5SD-B User’s Manual

3: Reconfiguring Your Mainboard – 3.10

Configuring External Clock Speed & Factor

To configure the board for a CPU’s internal clock speed, you

have to set the external clock speed (sometimes referred to as the
bus speed) and the clock factor so that the result is the internal
clock speed of the CPU you are installing. For example, the de­fault setting for these is:

66.6MHZ [external clock] x 3.0 [clock factor] =199.8MHz
or, an effective setting of 200MHz.
Since the internal clock speed the CPU is supposed to operate

at is fixed, the two factors, external clock and clock factor, are the
variables. The CPU manufacturer or vendor’s information should
tell you what these factors should be.

P Rated CPUs

Cyrix, IBM and AMD all make Pentium®-class CPUs that are

performance rated at an Intel Pentium
tually may have a slower internal clock speed. This ‘P’ rating is
used to indicate the CPU’s performance rather than its internal
clock speed. For example, the Cyrix/IBM P200 has an actual in­ternal clock speed of 150MHz. If you install a CPU of this type,
make sure you set the mainboard for the actual internal clock
speed of the CPU, not its P rating.

®

equivalent speed but ac-

Configuring CPU Voltage

The CPU voltage specification should also be provided in in-

formation from the manufacturer or vendor. Standard Pentium
CPUs are single voltage. MMX Pentiums® are dual-voltage. You
should set the CPU Voltage jumpers according to the specifica­tions you get with the CPU.

Adding An IDE Peripheral

This section covers some aspects of installing internal IDE pe­ripheral devices as they relate to the mainboard. The onboard
Enhanced IDE controller supports up to four devices, two per
IDE channel. The primary hard disk drive in most systems is an
IDE device. You may want to install more hard disks, a CD-ROM
drive or combination of these and other devices. This mainboard
supports both PIO and UltraDMA modes, which it can detect
automatically. You can install a mix of devices. With the Setup
Defaults loaded in the CMOS Setup utility , the system will auto­matically detect and configure multiple devices of whatever mode.

IDE Transfer Modes

Hard disk read and write operations are executed via the main­board chipset. The transfer of data between the hard disk and the
system takes place using one of a number of transfer modes –
either one of several PIO modes or UltaDMA mode.

Although there are several PIO Modes (0 through 4), and this
mainboard supports all of them, most current hard disk and CD­ROM drives use either Mode 3 or 4. The greater the mode num­ber, the faster the transfer rate, so you should use the fastest mode
the device can operate at. With Setup Defaults loaded in the
CMOS Setup Utility, the system will automatically detect the
fastest mode a device can use and set it for that mode.

UltraDMA is another transfer method that provides even faster
data transfer than PIO modes. To use it you must install a drive
that uses this transfer method. Drives that use PIO Mode transfer
can not use the UltraDMA setting.

The settings for drive modes are in the Integrated Peripherals
section of the CMOS Setup utility . The screen illustration at right
shows the Setup Defaults settings.

this screen. Y ou can install IDE

and the system will automati­cally detect and set the best
mode for each device.

You can also set the transfer
mode for each device manu­ally, although we recom­mend using the default set­tings unless you have a rea­son not to and you know what
you are doing.

P5SD-B User’s Manual

3: Reconfiguring Your Mainboard – 3.18

Installing IDE Devices

The mainboard’s Enhanced IDE controller supports four de­vices in two channels, IDE1 and IDE2. These are called the Pri­mary and Secondary IDE channels.

Each channel supports two devices, the first device is called
the Master device and the second the Slave device. You must
configure any IDE device you install to operate as one or the
other. To find out how to configure the device you plan to install
you should refer to the manual that comes with the device. You
may need to set jumpers or switches to configure it.

IDE Cables

The mainboard comes with one IDE ribbon cable to connect
two devices to the mainboard. If you need to install devices on
the second channel you will need to get another IDE cable. These
are a standard and inexpensive item that you can generally find
at any computer supply store. One edge of the cable is colored to
indicate the Pin 1 side. When you connect the cable to the main­board and a device you must orient the cable so that this colored
edge is at the Pin 1 side of the connector you are attaching it to.

The mainboard IDE connectors have an orientation cut-out to
ensure correct orientation, and the supplied cable has an orienta­tion tab on the side of the connector. Some IDE cables do not
have this tab and therefore are not forced to use the correct orien­tation. You should check that any cable you buy has orientation
tabs on the side of the connectors. If you get a cable that does not
have them, make sure the cable is correctly oriented when you
attach it to the board and the device.

P5SD-B User’s Manual

3: Reconfiguring Your Mainboard – 3.19

IDE cables have three connectors on them, one at each end
and one in-between, closer to one of the ends. When you install
a device on the second channel, attach the lone end to the IDE2
connector on the mainboard. The two connectors that are closer
to each other are for connecting to IDE devices. The connector
on the end is for the Master device and the connector in the middle
is for the Slave device.

IDE Devices & CMOS Setup

When you install a new hard disk drive its parameters will be
automatically detected by the BIOS and entered in the Standard
CMOS Setup section of the CMOS Setup utility if you use the
Setup Defaults, which automatically detect any new hard disk
drive. All other devices do not use drive parameters and will not
show up in the device list on this page.

Installing an AGP Card

An AGP display card installs in the AGP slot on the main­board and secures to the system case at the matching expansion
slot opening. Any AGP card will require Operating System sup­port, which will be implemented in Windows 98 and later ver­sions of Microsoft Windows.

Review the card documentation for any additional installa­tion instructions.

Adjusting The AGP Memory Aperture

If you install an AGP display card, you may want to use some
portion of the system memory for the AGP cards 3D support
features. The AGP Memory Aperture line in the CMOS Setup
Utility’s Chipset Features Setup section sets the amount of
memory available to the AGP card. The default setting is 64MB,
but you can adjudt this from 4MB to 256MB. The memory aper­ture is not dedicated to the AGP card. When the card is not using
it, the aperture memory is available to the system.

To decide what size aperture to use, consult you AGP card
documentation and the documentation for any 3D progarms you
plan to use.

System Memory Specifications

The memory subsystem has four 72-pin SIMM sockets di­vided into two banks, SIMM1 & SIMM2 and SIMM3 & SIMM4.
It also has two DIMM sockets. You cannot use SIMMs and
DIMMs at the same time on this mainboard.

SIMM modules should use either Fast Page Mode (FPM) or
EDO 5-Volt DRAM. You can use modules from 4MB to 128MB,
either single or double-sided. DIMM modules must use 3.3-Volt
unbuffered EDO or SDRAM. Total supported memor y capacity
is 256MB.

Memory Configurations

SIMMs install in pairs. You can install any SIMM memory
combination as long as you follow the basic requirement of in­stalling identical modules in both sockets of a bank, i.e.:

• 5-Volt modules

• Both modules are the same size, e.g. 16MB (MegaBytes)

• Both are the same DRAM memory type, e.g. EDO

• Both use the same operating speed, e.g. 60ns (nanoseconds)

Each DIMM is a memory Bank. You can install DIMMs with
these specifications:

• 8MB to 128 MB single or double-sided modules

• 3.3-Volt unbuffered EDO or SDRAM DRAM modules only

Other than these requirements, there is no limitation on the
variety of possible combinations, so they are not listed here.

N

Note: It is possible to install more memory than the board
supports. Do not install more than 256MB on this mainboard,
the system will ignore additional memory.

You can not use SIMM and
DIMM modules at the same
time on this mainboard.

CMOS Setup Utility Summary

This section explains the entries in the CMOS Setup Utility

program. This utility is permanently stored on the BIOS chip on
the mainboard. It creates a record of the mainboard’s and some
system configuration information and stores it in battery-sup­ported memory on the mainboard. This record must be intact
and accurate in order for the mainboard to operate.

After a brief explanation of how to operate the utility there is

a summary of the entries and options for all sections of the util­ity. Under normal conditions, once your system is set up, you
should have little or no need to use this utility.

Using the CMOS Setup Utility

This mainboard uses the Award system BIOS. It is stored in a

Flash ROM memory chip on the mainboard. The BIOS uses a
software program, also stored on the same chip to create a sys­tem configuration record which is saved in a small amount of
special “CMOS” memory on the mainboard.

Accessing The CMOS Setup Utility

When you turn on your computer, a message appears on the

screen indicating you can run the Setup program by pressing the
Del key (it’s on the keypad.) The message appears after the POST
(Power On Self Test).

If you want to run Setup but you don’t respond in time before

the message disappears, you can reset the system by pressing the
Ctrl + Alt + Delete keys at the same time, or by pushing the
system Reset button. The message will then reappear.

After you press the Del or Delete key the program menu screen

will appear, displaying the Setup utility section names and some
command instructions.

Large Hard Disk Modes

The last of the drive parameter entries – Mode – has four op-

tions, Normal, LBA, Large and Auto. The Mode settings are for
IDE hard disks only.

Normal
For IDE hard disks of 528MB or less.
LBA
This stands for Logical Block Addressing, the current standard

access mode for large IDE hard disk drives. It allows the use of
hard disks larger than 528MB by causing the IDE controller to
translate between the logical address it creates and the hard
disk’s actual physical address. The maximum drive size sup­ported is 8.4GB.

Large
For 1GB or smaller drives with more than 1024 cylinders and

no LBA support. This access mode causes the Operating Sys­tem to treat the drive as if it has fewer than 1024 cylinders by
dividing the cylinder total in half and doubling the number of
heads. Drives needing this mode are less common.

Most large IDE hard disk drives currently available use the

LBA mode. Use the AUTO setting to automatically detect the
correct mode for new drives.

What Power Management Does

Power management lets you set up your computer to save

electricity when it is not actively in use by putting the system
into progressively greater power saving modes. In the power man­agement scheme there are four system states which proceed in
the following sequence:

Normal
Doze
Standby
Suspend

This controls the entire power management scheme. There

are four settings:
User Defined

You set the power saving options manually

Disable

Turns off all power management

Max Saving

Maximizes power saving by activating maximum power sav­ing settings after one minute of system inactivity

Min Saving

Produces less power saving by activating moderate power sav­ing settings after one hour of system inactivity

PM Control By APM

Video Off Method

This governs monitor power saving by controlling how power
management blanks the monitor screen. The V/H Sync+Blank
blanks the screen, turns off scanning and requires a monitor with
“green” features. If you don’t have this type of monitor, use the
Blank option. DPMS (Display Power Management System) al­lows the BIOS to control the display card if the it has the DPMS
feature.

Standby Mode

This sets the period of system inactivity after which the sys-

tem goes into Standby mode, the intermediate power saving state.
The settings range from 1 minute to 1 hour and can be set manu­ally when power management is in User Define mode. The de­fault setting is Disabled. When the system goes into power sav­ing mode, power management will skip to the next mode in the
