Install the Processor

This mainboard has a Slot-1 which can be installed with Slot-1
processor cartridge including the Pentium-II, Pentium-III, and the
SEPP Celeron. It also has a Socket-370 which can be installed with
the PPGA Celeron or FCPGA Pentium III processor.

To ensure reliability, make sure that your PPGA/FCPGA
processor is fitted with a heatsink/cooling fan assembly.

You can install a Slot-1 processor or a Socket-370 processor. You
cannot install both a Slot-1 CPU and a Socket-370 CPU.

Take care that you do not try to install a Socket-7 processor into
the Socket-370. A Socket-7 processor such as the Pentium-MMX,
or the AMD K5/K6 does not fit in the socket-370.

Installing a Slot-1 Processor Cartridge

1. Locate Slot-1, and CPUFAN1 on the mainboard.

CPUFAN1

Slot-1 with pre-installed
cartridge holder. The
upright arms are folded
down for shipping.

2. The Slot-1 is installed with a cartridge holder. The upright
struts of the cartridge holder are folded down for shipping. Pull
the struts upwards so that they are in the upright position.

3. Insert the processor cartridge into the cartridge holder. Follow
the instructions given with your processor cartridge. The edge
connector on the cartridge has a notch so that it only fits into
the Slot-1 in the correct way.

4. Locate the cooling fan power supply CPUFAN1. Connect the
cable from the processor cartridge cooling fan to CPUFAN1.

5. On this mainboard, you can configure the processor by
entering the correct settings in the BIOS setup utility.

Installing a Socket-370 Processor

The processor installs into the ZIF (Zero Insertion Force) Socket­370 on the mainboard.

1. Locate the Socket-370, and CPUFAN1. Pull the locking lever
out from the socket and swing it to the upright position.

Pin-1 Corner

CPUFAN1

Socket-370

2. On the processor, identify the pin-1 corner by noting that it has
a slight bevel.

3. On the Socket-370, identify the pin-1 corner. The pin-1 corner
is on the same side as the locking lever, closest to the top of the
lever when it is in the locked position.

4. Match the pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.

5. Swing the locking lever down and hook it under the catch on
the side of the socket. This locks the processor in the socket.

6. If the processor is installed with a cooling fan assembly,
connect the cable from the fan to the CPU fan power connector
CPUFAN1.

Install Memory

The mainboard has two DIMM slots which can be installed with
memory modules. You must install at least one memory module in
order to use the mainboard.

DIMM1

DIMM2

For this mainboard, you must use 168-pin, 3.3V memory modules
installed with SDRAM memory chips. You must use memory that
operates on a 100 MHz memory bus (PC-100 memory). You can
install any size of memory module from 16 MB up to 256 MB, so
the maximum memory size is 2 x 256 MB = 512 MB.

The edge connectors on the memory modules have cut outs, which
coincide with struts in the DIMM slots, so the memory modules
can only be installed in the correct way.

On the DIMM slot, pull the locking latches at either end of the
slots outwards. Position the memory module correctly and insert it
into the DIMM slot. Press the module down into the slot so that the
locking latches lever inwards and lock the module in place.

Set the Jumpers

Jumpers are sets of pins that can be connected together with
jumper caps. The jumper caps change the way the mainboard
operates by changing the electronic circuits on the mainboard. If a
jumper cap connects two pins, we say the pins are SHORT. If a
jumper cap is removed from two pins, the pins are OPEN.

expansion slots and install the extension bracket in the slot.
Use the screw that held the blanking plate in place to secure
the extension bracket.

Install Other Devices

Install and connect any other devices in the system following the
steps below.

Floppy Disk Drive

The mainboard ships with a floppy disk drive cable that can
support one or two drives. Drives can be 3.5” or 5.25” wide, with
capacities of 360K, 720K, 1.2MB, 1.44MB, or 2.88MB.

Install your drives and supply power from the system power unit.
Use the cable provided to connect the drives to the floppy disk
drive header FDD1.

IDE Devices

IDE devices include hard disk drives, high-density diskette drives,
and CD-ROM/DVD drives.

The mainboard ships with an IDE cable that can support one or two
IDE devices. If you connect two devices to a single cable, you
must configure one of the drives as Master and one of the drives as
Slave. The documentation of the IDE device will tell you how to
configure for Master or Slave.

Install the device(s) and supply power from the system power unit.
Use the cable provided to connect the device(s) to the Primary IDE
channel connector IDE1 on the mainboard.

IDE1

If you want to install more IDE devices, you can purchase a second
IDE cable and connect one or two devices to the Secondary IDE
channel connector IDE2 on the mainboard. If you have two devices
on the cable, one must be Master and one must be Slave.

Internal Sound Connections

If you have installed a CD-ROM drive or a DVD drive, you can
connect the sound output of the drive to the built-in sound system.

On the mainboard, locate the two 4-pin connectors for CDIN1 and
CDIN2. There are two kinds of connector because different brands
of CD-ROM drive have different kinds of cable connectors on their
audio output cable. Connect the cable to the appropriate connector.

Infrared Port

You can install the mainboard with an optional infrared port. You
can purchase these options from third-party vendors.

1. On the mainboard locate the infrared port header SIR1.

2. Connect the cable from the infrared port to the infrared header
SIR1 and then secure the infrared port to an appropriate place
in the system chassis.

Expansion Slots

This mainboard has three 32-bit PCI expansion slots and one AMR
slot. The PCI1 slot is shared with the onboard VGA and the
onboard Modem, and the PCI3 slot is shared with the onboard

LAN. It means that you can use either one of shared both but you
cannot use the both at the same time.

AMR Slot

The AMR (Audio Modem Riser) slot is an industry standard slot
that allows for the installation of a special audio/modem riser card.
Different territories have different regulations regarding the
specifications of a modem card. You can purchase an AMR card
that is approved in your area and install it directly into the AMR
slot.

2. Remove the blanking plate from the appropriate expansion slot
on the system chassis.

3. Install the edge connector of the expansion card into the slot
and press it quite firmly down so that it is seated correctly.

4. Secure the bracket of the card into the expansion slot in the
system chassis using the screw that held the blanking plate in
place.

Note: If you have installed an AMR card, you should check the
settings of jumpers JP4 (audio/modem enable/disable) and JP6
(select onboard codec or AMR codec). You should disable the
onboard audio/modem to avoid conflicts with the AMR card. You
can use the AMR codec chip (if it has one) or the onboard codec
chip.

Wake On LAN

If you have installed a LAN adapter card, connect the card to the
wake on LAN header WOL1. This allows incoming traffic to
resume the system from a software power down.

Wake On Modem

If you have installed a fax/modem card, connect the fax/modem to
the wake on modem connector WOM1. You can then use the setup
utility to program your computer to resume from a power saving
mode whenever there is an incoming call to the fax/modem.

Chapter 3

BIOS Setup

Introduction

The BIOS setup utility stores information about your computer
such as the date and time, the kind of hardware you have installed,
and so on. Your computer uses this information to initialize all the
components at boot up time, and make sure that everything runs
smoothly.

If the information in the setup utility is incorrect, it may cause your
system to malfunction. It can even stop your computer from
booting properly. If this happens, you can use the clear CMOS
jumper to clear the CMOS memory area that is used to store the
setup information, or you can hold down the End key while you
reboot your computer, Holding down the End key also clears the
setup information.

You can run the setup utility and manually make changes to the
setup utility. You might need to do this to configure some of the
hardware that you add to the mainboard, such as the CPU, the
memory, disk drive, etc.

Running the Setup Utility

Each time your computer starts, before the operating system is
booted, a message appears on the screen that prompts “Hit <DEL>
if you want to run SETUP”. When you see this message, press the
Delete key and the Mainmenu page of the setup utility appears on
your monitor.

You can use the cursor arrow keys to highlight any of the options
on the Mainmenu page. Press Enter to select the highlighted
option. To leave the setup utility, press the Escape key. Hold down
the Shift key and press F2 to cycle through the optional color
schemes of the setup utility.

Some of the options on the Mainmenu page lead to tables of items
with installed values. In these pages, use the cursor arrow keys to
highlight the items, and then use the PgUp and PgDn keys to cycle
through the alternate values for each of the items. Other options on
the Mainmenu page lead to dialog boxes which require you to
answer Yes or No by hitting the Y or N keys.

If you have already made changes to the setup utility, press F10 to
save those changes and exit the utility. Press F5 to reset the
changes to the original values. Press F6 to install the setup utility

with a set of default values. Press F7 to install the setup utility with
a set of best-performance values.

Standard CMOS Setup Page

Use this page to set basic information such as the date and time, the
IDE devices, and the diskette drives. If you press the F3 key, the
system will automatically detect and configure the hard disks on
the IDE channels.

Auto-Installing under Windows 98

During the installation under Win98 OS, the setup program will
automatically find out and match the proper drivers for the
hardware of your system. However, Windows might not be able to
detect some of your new hardware.
Please follow the steps listed below to install drivers and
applications for your system.

1. Put the support CD into CD-ROM drive.

2. The setup window will appear as below.

3. Click Setup button to continue.

4. Click Next button to continue.

5. Select the items that you want to setup by clicking on it (the
default options are recommended). Click the Next button to
proceed.

6. The support software will automatically install.

Once any of the installation procedures start, software is
automatically installed in sequence. You will need to follow the
onscreen instructions, confirm commands and allow the computer
to restart as few times as is needed to complete installing whatever
software you selected to install. When the process is finished, all
the support software will be installed and working.

There are some utilities that you have to manually install if you
need, check to the above section.

Using the PCI Sound Pro Application

1. Before you install the Sound drivers, make sure your Operating
System has been installed, otherwise the PCI Sound Pro might
be detected as “Other device” by the device manager of your
OS.

2. After the drivers are properly installed, choose the
MULTIMEDIA icon in the CONTROL PANEL when you
need to use the Software Wave-Table drivers as a MIDI output
device. Select the MIDI page and click on “C-media SoftMidi
Synthesis (Win98) / Driver (Win95)”, then click “OK” to
confirm.

3. A Windows application named Audio Rack is provided with
the Sound drivers, which gives you control over all the audio
functions through a user interface that is as simple to use as a
home stereo system. We recommend that you use the System
Mixer in the Audio Rack software to control your computer’s
audio volume, recording device and the recording gain.

4. If the devices that you are using require the MIDI port as the
control interface, you need to select the MULTIMEDIA icon
in the CONTROL PANEL. Select the MIDI page and click on
“CM8738 MPU-401” (Win98) or “CM8738/C3DX PCI Audio
External MIDI Port” (Win95), and then click “OK” to confirm.

5. For more information, refer to the PCI Sound Pro manual in
the CD which ships with this mainboard.

The Four Speakers System

The onboard Sound Pro audio system supports 2 wave channels
(front/rear) known as the 4 speaker system. If you are running
applications which use the DirectSound® 3D or A3D® audio
interface, your system can simulate realistic 3D sound through a 4
speaker setup. Follow the steps below to install a 4-speaker setup.

Speaker Installation

Connect the front two speakers to the Line-out jack on the sound
ports extension bracket. Connect the rear two speakers to the Line­in/Rear jack on the sound ports extension bracket. The original
Line-in can be moved to Aux.

Speaker Position

Set up your speakers similar to the following figure to get the best
audio result.

Mixer Setup

There is a 4-speakers option in the Volume Control of the Mixer
when you are setting up the PCI Audio Application. Click on the 4
SPK icon to enable this option. This means that the output to the
rear speakers is sent through the Line-in/Rear jack. In order to
avoid hardware conflicts, DO NOT enable this option when the
Line-in/Rear jack is connected with a line-in device. While the 4

speakers mode is enabled, turn on/off the output of the front
speakers and adjust the volume of the speakers so that the
front/rear speakers have the same volume.

Demo

Execute the “Helicopter” demo in the C3D HRTF Positional Audio
Demos of the PCI Audio Application. When you hear the
helicopter flying behind you, it means that the rear speakers are
working properly.
