the Slot-1 in the correct way.

4. Locate the cooling fan power supply FAN1. Connect the cable
from the processor cartridge cooling fan to FAN1.

5. Locate the jumper J20. Use this jumper to short pins 2-3 if you
have installed a Slot-1 processor.

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

Installing a Socket -370 Processor

The Celeron processor installs into the ZIF (Zero Insertion Force)
Socket -370 on the mainboard.

1. Locate the Socket-370, FAN1, and J20. Pull the locking lever

Pin-1 Corner

2. On the Celeron 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 Celeron 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 Celeron processor in the
socket.

6. Locate the jumper J20. Use this jumper to short pins 1-2 if you
have installed a Socket -370 processor.

7. If the Celeron processor is installed with a cooling fan
assembly, connect the cable from the fan to the CPU fan power
connector FAN1.

Install Memory

The mainboard has three DIMM slots which can be installed with
memory modules. You must install at least one memory module in
order to use the mainboard. You must install the first memory
module into DIMM1 so that it can share memory with the onboard
VGA system.

For this mainboard, you must use 168-pin, 3.3V memory modules
installed with SDRAM memory chips. If you are using a processor

that runs on a 100 MHz system bus, you must use memory that
operates on a 100 MHz memory bus (PC-100 memory). If you are
using a processor that runs on a 66 MHz system bus, you must use
memory that operates on a 66 MHz memory bus. You can install
any size of memory module from 16 MB up to 256 MB, so the
maximum memory size is 3 x 256 MB = 768 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 which 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.

Jumper J10: Keyboard Power On Selector

If you enable the keyboard power on feature, you can use hot keys
on your keyboard as a power on/off switch for the system.

Note: Make sure that the system can provide 1A on +5VSB (+5V
Standby) signal before using the Keyboard Power On function.

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 comp uter 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
setup in formation.

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.

Using the PCI Sound Application

1. Before you install the PCI Sound drivers, make sure your
Operating System has been installed, otherwise the PCI Sound

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 PCI 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 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 Line ­in/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.
