MOTHERBOARD User’s Manual
Installing System Memory
There are two system memory sockets on the
motherboard. They use 3.3Volt, non-buffered
SDRAM DIMMs (Dual In-line Memory Module).
This motherboard uses either PC100 or PC133
DIMMs. The motherboard will automatically detect and configure the installed memory. This
means you can use PC100 memory even if the
external clock frequency used by the CPU is
66MHz. You can install any size DIMM from
16MB to 256MB in either socket in any order for a
total of 512MB.
Installing DIMMs
The DIMM sockets have three edge connector
sections divided by spacers with a crossbar. The
crossbars match cut-outs in the DIMMs so that
only the correct type of module can be installed.
The cutouts vary by module type. Make sure you
use the correct module type as noted above. When
installing memory, you should take precautions
against static electric damage to sensitive components on the modules and the motherboard. To
install a module does as follows:
1. Press the socket retaining latches down to create full access to the socket.
2. Align the DIMM to the socket so that its edge
connector matches the socket’s connectors.
The three sections are of different lengths to
make the correct orientation obvious.
18
3. Lightly press the DIMM into the socket at a
90º to the motherboard. Make sure the mo dule and the socket are lined up correctly.
Configuration & Installation
4. Press the DIMM fully into the socket. The
retaining latches will rotate upwards and
should fit into the corresponding notches on
the DIMM. Press the latches into place if ne cessary. If the latches won’t insert properly into
the module notches push them back and try
inserting the DIMM again. When the latches
are fully in place the DIMM is properly installed.
2
Depending on the module size and the total capacity you want to install, you may install memory in only one or both sockets. For example, to
install 128MB of system memory you can install
either one 128MB DIMM in one socket or two
64MB modules using both sockets. We recommend that you use the largest module that fits
your installation plans so that you can leave the
second socket open for later upgrades.
If you want to upgrade system memory after the
motherboard is installed you can install additional
memory in the empty socket. If there is no empty
socket, you will need to remove at least one module and replace it with the upgrade module. In
some cases, you may need to remove both modules to allow installing your intended configuration. To remove a DIMM do as follows.
19
MOTHERBOARD User’s Manual
1. Make sure the computer is turned off and unplugged.
2. Press down on the retaining latches to release
the module and push it partially out of the
socket.
3. Carefully remove the module from the socket,
preferably grasping it by the top corners of the
circuit board.
Installing Options
To install any optional hardware such as the Modem Riser card or optional Infrared port you must
first install the motherboard in a system housing.
Please refer to the Other Connections portion of
the next section.

Installing The Motherboard
This section is a brief generic explanation of how
to install the motherboard in a system housing
(“case” or “chassis”) and connect other internal
system components to it. If you are not experienced at installing and assembling computer
hardware we recommend you consider having a
qualified service technician install and assemble
your system for you. If you will do the work you rself, make sure to take precautions against damage
from static electric discharge while installing and
connecting components.
Installing in a System Housing
Since housing designs vary considerably the section provides general guidelines and notes the basic requirements. This motherboard is a Baby AT
board that requires either a Baby AT or AT case
(chassis) and power supply. The case should come
with mounting hardware for the motherboard and
at least basic instructions on how to install a
motherboard. It is advisable to check the case before you by it and confirm that it has adequate
hardware and instructions. If you are upgrading
the motherboard in a system you already own,
you will need to make sure your system case can
accommodate this motherboard.
This is the basic procedure to install the motherboard:
1. Check over the hardware and instructions that
came with the system housing and make sure
everything is there and that you understand
the instructions.
21
MOTHERBOARD User’s Manual
2. Attach whatever mounting hardware is needed
to the case. Some cases support more than one
motherboard form factor, for example Baby
AT, Micro ATX and ATX. Identify the
mounting points that match as many of the
mounting holes on the motherboard as possible and install hardware at those points. Some
cases use both metal nut-headed screws and
plastic spacers with a pointed end that inserts
in a mounting hole on the motherboard. The
spacers fit into slots in the motherboard
mounting plate.
3. Install a port cover panel if necessary (for hybrid AT/ATX cases). Follow the instructions
that came with the case and make sure you
use a cover panel for the AT board.
4. Line the motherboard mounting holes up with
the appropriate attachment points on the
motherboard mounting plate. If you had to install plastic spacers in some holes, make sure
they fit into their slots as you align the board.
5. Use the mounting screws and washers that
came with the system case to attach the motherboard to the mounting plate. Seat the screws
firmly but not to tightly.
With the motherboard installed, you can now attach internal system components including wire
leads from the system case and disk drive or other
22
cables and port brackets.
Configuration & Installation

System Housing Connections
You will need to connect several wires from the
system housing to the motherboard. These include
leads for functions on the housing’s front panel
and the power connector from an AT or ATX
power supply and any system cooling fans.
Connecting Front Panel Leads
System housings usually have several system controls and indicators mounted on the front panel.
This motherboard supports several of these standard features via the J20 Switch & Indicator panel
connector. The supported features and the pins
J20 they connect to are shown in the following
table and figures.

Connecting AT or ATX Power
The power connector from the ATX power supply
is a rectangular plastic connector with multiple
wires running back to the power supply. It plugs
onto the ATX power connector on the motherboard. The connector will only plug on one way,
so if it won’t plug on easily, turn it around and try
again. Make sure the power supply is unplugged
when you connect the power lead.
An AT power supply has two leads with connectors that plug onto the AT power connector. Make
sure the black wires are in the middle after you
plug them onto the board.
Fan Out
+5V
Connecting Cooling Fans
There are two connectors on the motherboard for
connecting power leads from system cooling fans
mounted in the system housing. The system
housing may already have such a fan installed. If
so, you should connect it to the nearest connector
on the motherboard. Many cases have a space to
install a standard cooling fan. The fan power leads
will only plug on one way so you can’ t connect
them incorrectly.

The end drive connector on the ribbon cable is for
the Master IDE device and the middle connector
is for the Slave device. The supplied cable supports
IDE devices in all modes.
If you want to install devices on the second IDE
channel, you will need to purchase an additional
IDE ribbon cable. If you want to use IDE devices
that use the UDMA66 data transfer mode, you
will need to get an IDE cable that specifically supports UDMA/66 like the supplied cable.
Other Connections
There are several other connection points on the
motherboard which you will or may need to use.
These include the port bracket connectors, the
connectors for CD-ROM drive audio input and
the IR port connector.

Checking The Installation
Once you have installed and connected internal
peripherals -- most likely at least a hard disk drive,
a floppy disk drive and a CD-ROM drive – check
and make sure everything is correctly and firmly
connected or installed. After that, assemble the
system housing and connect a monitor, keyboard
and mouse or other pointing device. Plug the
power cord into the power supply and plug it into
a surge-protected power outlet.
Turn on the computer. The POST (Power On Self
Test) will run and should display the correct
memory total. The default BIOS settings should
automatically detect and configure any floppy disk
drives and IDE devices as well as assign resources
for any expansion cards you may have installed. If
you encounter a problem, reboot and run the
CMOS Setup Utility by pressing the delete key. If
you need help using the utility, see Chapter 4. The
system should now be ready to install an Operating System on the hard disk drive and the necessary support software from the Support Disk.
Support Software
All versions of this motherboard come with a
software Support Disk that has both support software and bundled software on it. The Support
Disk is for an entire range of motherboards. There
is more software on the Support Disk than is used
by this motherboard, so don’t be confused by the
30
software that doesn’t apply. A n Operating System
must be installed on the primary system hard disk
drive before you can install support software. Most
of the support software is for Microsoft Windows
95, 98 or NT as these are the operating Systems
most likely to be used with this motherboard.
Configuration & Installation
2
Installing the Support Software
The Support Disk is set to run automatically. The
disk has an installation interface that will appear
when you load the disk in the CD-ROM drive.
You can then make selections from the menu that
appears by clicking on an item with the mouse.
You can also use the arrow keys on the keyboard
to make a selection and then press the Enter key.
The installation interface has a number of nested
levels. The top level, which you see when the disk
loads looks like the following figure. You can exit
the level you are in either by clicking on the Exit
bar, selecting it and pressing the Enter key or by
pressing the Esc key. The top level Exit bar closes
the installation program.
You will need to install the SiS 630 support software under the SiS Series heading. Installing the
other bundled software is optional.

Upgrading System
Memory
Using The Motherboard
This chapter covers a few points on how some of
the motherboard features impact use of the computer it is installed in. This includes using system
control features, connecting external peripherals,
installing expansion cards and upgrading system
memory.
System Controls
There are several system controls that either connect to the motherboard from the front panel of
the system housing or work through the keyboard
or pointing device.
Front Panel Features
System housings vary in design, so a particular
system case may not support all the features on
the motherboard. Most housing do support the
majority of these features however. The location
and appearance of these features will vary according to the housing design.
The Power Button
The power switch on an ATX case is likely to be a
power button that can do more than function as
an on/off switch. You can set how the power button works in the BIOS CMOS Setup Utility. The
button can either function as instant on/off or as
suspend/off after 4 second delay. You can config-
36
ure the power button under the Soft-OFF by
PWR-BTTN line in the Power Management Setup
section of the CMOS Setup Utility.
AT power supplies do not support this feature.
Using The Motherboard
The Reset Switch
A reset switch is standard to almost all PCs.
Pushing the switch will cause the computer to do
a “hard” restart. If the computer hangs during
operation and becomes unresponsive to other controls, you can restart the computer using this
switch. Don’t use it if the computer is operating
normally. You should always shut down from
within the Operating System. Only use reset as a
last resort and instead of turning the computer off
and then back on.
The Suspend Button
An external Suspend button appears on some
3
cases. Pushing the button will cause the system to
enter whatever power-saving suspend or “Sleep”
mode it is configured to enter. In suspend mode
the computer may appear to be turned off, but is
in fact just in a low power mode. Don’ t turn the
computer off when it is suspended. Pushing the
button while the system is suspended will resume
or “Wake Up” the system and cause it to return to
its previous state.
Indicator Lights
The motherboard supports several indicator lights
that may be present on the front panel of the sy stem housing. These include a Power LED, a Hard
Disk Drive LED and a Suspend LED.
• Power LED: Lights when the system is on
• Hard Disk Drive LED: Flashes when the hard
disk drive is being accessed
• Suspend LED: Lights when the system is in
power saving Suspend or “ACPI” mode

Connecting External Peripherals
This section covers information on connecting
external peripheral equipment to the computer via
the motherboard’s onboard ports. This motherboard has a full complement of external ports including all standard I/O ports and a VGA video
display port.
Connecting Peripherals to
Conventional Ports
It is safest to turn the computer off before connecting or disconnecting any external peripherals.
The “conventional” ports on this motherboard are
color-coded according to the PC99 standard. This
allows for easier system setup when using similarly color-coded peripheral cable connectors. The
port colors and functions are as follows:
• Parallel port [Burgundy]: Generally used for
connecting a printer. Usually configured as
LPT1. Can also connect to other devices designed to use this port. More than one device
can be connected to the port by using a “passthrough” cable. The port supports multiple
modes and is configurable via the BIOS
CMOS Setup Utility in the Integrated
Peripherals section of the utility. Any device
connected will also require Operating System
driver support.
38
Using The Motherboard
• Serial ports [Teal]: Used for connecting modems, printers and other serial devices. The
port supports multiple address configurations
and is configurable via the BIOS CMOS Setup
Utility in the Integrated Peripherals section of
the utility. Any device connected will also require Operating System driver support.
• Keyboard port [Purple]: For a PS/2compatible keyboard.
• Mouse port [Green]: For a PS/2-compatible
pointing device. Driver support for basic
pointing devices such as a standard 2-button
mouse is not required under Windows. Enhanced pointing devices require a driver for
3
their added functionality.
• Audio jacks:
• Audio Line Out [Lime]: Uses a mini-plug
cable connector to output to external
audio, either speakers or an amplifier.
• Audio Line In [Light Blue]: Uses a mini-
plug cable connector to receive audio input from an external source such as an
audio CD or MP3 player.
• Microphone [Pink]: Uses a mini-plug ca-
ble connector to receive audio input from
a microphone.
• Game/MIDI port [Gold]: This port can functions as either a Game port or as a MIDI port.
The port is configurable via the BIOS CMOS
Setup Utility in the Integrated Peripherals section of the utility. The default configuration
for this port is as a Game port. If you configure the port as a MIDI port, it will need to use
either IRQ 5 or 10.
39
MOTHERBOARD User’s Manual

Connecting USB Peripherals
The motherboard has support for two Universal
Serial Bus ports. There is a pin connector on the
board for an optional USB port bracket that you
can purchase separately if you want to use the
USB feature.
You can connect USB devices to either the USB
ports directly or to a bus-powered or self-powered
USB hub which provide more ports. The bus
provides limited power. A powered hub increases
the number of powered devices you can connect
to the bus. Some USB devices may also have their
own power source. USB devices are “hot swappable” which means you don’ t have to turn the
computer off before connecting or disconnecting a
USB device. USB supports up to 127 devices.
USB is an interface for peripherals that use a relatively low data transfer speed, such as USB keyboards, pointing devices, scanners, printers, modems and other telephony devices and game devices. USB also supports MPEG-1 and MPEG-2
digital video. It has a maximum transfer rate of
12Mbits per second, which is equivalent to 1.5MB
per second. To use the USB feature, the computer
must use an Operating System that supports it.
For example, all versions of Microsoft Windows
from Windows 95 OSR2 and later support USB.
Earlier versions of Windows do not support USB.

Installing Expansion Cards
This section has some general information on installing expansion cards on the motherboard. This
motherboard has five standard PCI expansion
slots. The slots are all 32-bit PCI Revision 2.2
compliant and are all Bus master capable. There is
another special slot for an optional Modem Riser
card. Note that there are no legacy ISA slots on
this motherboard.
Installing PCI Cards
There are several issues that affect your choice and
installation of expansion cards on the motherboard. These include Bus Master drivers, Plug and
Play and system power and resource considerations.
Bus Master Drivers
The PCI expansion slots are all Bus Master capable. The Bus Master feature can substantially improve system performance and also is used by the
onboard IDE channels. To make use of this feature under Windows 95 you will need to install the
default Windows 95 Bus Master driver. Later ve rsion of Windows do need a separate Bus Master
driver to take advantage of this capability.
41
MOTHERBOARD User’s Manual
3
Plug and Play
It is likely that any PCI card you will install on the
motherboard will be Plug and Play (PnP) compliant. Plug and Play is a design specification for expansion cards that allows the system to automatically assign and manage resources for installed
expansion cards rather than requiring manual configuration as in pre-PnP designs. Any new expansion cards you install are more than likely to be
PnP compliant. Some old PCI cards might possibly not be. Where you have the option, we suggest
not installing cards that are not PnP compliant as
it simplifies the management of system resources.
System Resources & Power Limitations
Many expansion cards require the use of system
resources such IRQ and DMA channels. By design, all PCs have a limited number of these resources and their proper configuration is fundamental to proper system operation. As noted in
the previous section, the PnP feature handles the
management of system resources. The problem is
that these resources are finite. If you install
enough expansion cards and connect enough devices that use system resources to the various ports,
it is possible to run out of these resources. While
IRQs can be shared, there is a limit to doing so.
Resource conflicts and problems can result in operation problems.
42
Using The Motherboard
If you have a lot of cards installed and devices
connected it is a good idea to check the system
resource status. For example, if you are running
Windows 98, you can use the System Information
utility to examine system resource assignments.
An average configuration is unlikely to encounter
this problem so it is not something to be concerned about.
Power Considerations
The system power supply has a fixed electrical capacity measured in watts. If you install numerous
internal peripherals and expansion cards, for example four IDE devices, a SCSI card and internal
SCSI peripherals, it is possible to exceed the ca-
3
pacity of the power supply. Be aware of the total
wattage capacity of the power supply in the system and make sure that you don’t install more devices than it can handle.
Installing Cards
When the motherboard is installed in a system
housing the expansion slots all line up with access
openings in the rear of the case. These will be
covered with either individual slot covers or metal
plates. To install a card you have to remove the
slot cover.
Refer to the instructions that come with the expansion card you want to install for detailed information on installing the card and any special
considerations and instructions. For most new
cards, the hardware installation is simple. Always
turn off and unplug the computer before you install any expansion card.
43
MOTHERBOARD User’s Manual
3
Driver & Other Software
Many cards will require the installation of driver
or other software. Follow the software installation
instructions that come with the card. It is a good
idea to make sure that you have the most recent
driver for the card. In some cases, there may be an
updated driver on the company’s web site. If you
have Internet access, it is a good idea to check for
an updated driver before installing the card.
Installing A Modem Riser Card
The special Modem Riser slot is for a separately
purchased Modem Riser telephony card. The card
provides a V.90 modem and other telephony features and installs in the same way as a conventional expansion card although the slot is smaller.
The card has two external RJ-11 phone jacks on it,
one for Line-in and the other to connect out to a
telephone set. You should receive driver software
for the card. The driver software may only support
a limited number of Operating Systems so check
that the driver supports your OS before you buy
the card. Follow the instructions that come with
the card to install it.

Upgrading System Memory
There is a full explanation of how to install system
memory in Chapter 2. Please refer to it if you
need information on the installation procedure.
This motherboard uses 3.3V unbuffered SDRAM
168-pin DIMMs with SPD. It requires at least
PC100 SDRAM modules. It can also use PC133
DIMMs. The system will automatically detect the
memory clock speed and the speed can be different from the external clock frequency used by the
CPU.
If both sockets are occupied, you will need to remove one or both modules to install an upgrade. If
you’re only removing one module, always remove
the one with the smaller capacity.

What’s In This
Chapter:
The System BIOS &
CMOS Setup Utility
This section explains what the system BIOS does
System BIOS
CMOS Setup Utility
and has a summary of the CMOS Setup Utility.
The System BIOS
This motherboard uses the Award system BIOS.
The system BIOS (Basic Input Output System) is
firmware -- software stored on a chip -- that is
permanently stored on the motherboard’s Flash
ROM chip.
The BIOS is a set of routines which function as an
interface between the Operating System and the
system hardware. It supports the installed
peripherals and provides internal services such as
the realtime clock produces time and date data.
When the system is starting up, the BIOS tests the
system and prepares the computer for operation
by checking the CMOS memory where the system
configuration information is stored and retrieving
information on the configuration settings. When it
is finished it loads the operating system and passes
control of the system to it.
The system configuration information that the
BIOS retrieves from CMOS memory is recorded
there by the CMOS Setup Utility.
46
System BIOS & CMOS Setup Utility

The CMOS Setup Utility
This section explains the CMOS Setup Utility
program. The utility is permanently stored in the
Flash ROM chip on the motherboard. It creates a
record of the motherboard and some system configuration information and stores it in batterysupported CMOS memory. This configuration
record must be intact and accurate in order for the
motherboard to operate correctly.
After an explanation of how to operate the utility
there is a summary of the various sections of the
utility. Normally, once your system is set up, you
should have little or no need to use the utility.
Using the CMOS Setup Utility
This section explains how to access and use the
CMOS Setup Utility interface.
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 and the Delete key performs the same
function. The message appears at the end of 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.

General Troubleshooting
Once the motherboard is properly configured and
installed in a system, it should work without trouble. If the board does operate properly when you
first try to use it in the system, it is likely that it is
either incorrectly configured or there are connection problems. You always check the most basic
possibilities first to troubleshoot a problem. Check
the following:
• Make sure the computer and monitor are
plugged in and turned on.
• Check all external connections including
monitor, keyboard and mouse and ensure they
a properly connected.

Troubleshooting & Technical Summary
If there is still a problem check the following:
• Run the CMOS Setup Utility, load the Optimized Defaults, save and exit to restart the
computer. If there’s still a problem:
• Turn off and unplug the computer.
• Press the installed DIMMs into the sockets to
make sure they’re fully seated.
• Make sure the CPU is correctly installed.
• Check all hardware configuration settings on
the motherboard and ensure they are correct.
• Make sure you use the right cables to connect
internal peripherals and that the peripherals
are correctly connected. Pay particular atten-

Support Software Problems
There is a variety of software on the Support Disk.
If you install the wrong software, the motherboard
and the system may not operate properly.
Make sure you check the following:
• VGA driver: You must install the correct driver for the operating System you are using.
• Audio driver: Check that you have installed
the correct driver. Do not install anything from
the Audio section of the main menu. Only i nstall from the Audio Driver section of the SiS
630 driver software.
Battery Replacement
This motherboard uses a CR2032 Lithium coin
battery to maintain the system configuration record created by the BIOS CMOS Setup Utility.
The battery should last for several tears. If the ba ttery fails, the system will not be able to retain the
system settings and will not operate properly. If
this happens, do as follows:
• Turn off and unplug the system.
• Open the system and locate the battery on the
motherboard.
• Remove the old battery and dispose of it
properly.
• Install the replacement battery with the positive side (marked with a + sign) face up.

CPU Options
This motherboard can use any Intel Slot 1 CPU
running at speeds from 233MHz to 600MHz.
These include SECC Celeron, Pentium II and
Pentium III CPUs. The external clock frequency is
automatically detected in the default hardware
configuration. Frequency control is in the Frequency/Voltage Control Section of the BIOS
CMOS Setup Utility.
External clock speeds of 66MHz, 100MHz and
133MHz are available by jumper setting. Note that
not all Slot 1 CPUs support all external speeds.
An incorrect setting can result in CPU failure. The
Autodetect setting prevents this possibility and is
the recommended setting.
This motherboard can also use any Intel PPGA or
FCPGA Socket 370 CPU running at speeds from
300MHz to 600MHz. The external clock frequency is automatically detected in the default hardware configuration. Frequency controls are in the
Frequency/Voltage Control Section of the BIOS
CMOS Setup Utility.
System Memory Specification
This motherboard uses 3.3V unbuffered SDRAM
168-pin DIMMs with SPD. It requires at least
PC100 SDRAM modules. It can also use PC133
DIMMs. The system will autodetect the DIMM
clock.
