Unpacking the Mainboard & Static Electricity Precautions
This Mainboard package contains the following items: 1. This Mainboard and the Device Driver 2. This Users Guide and AT cables 3. SPDIF/IN cable(optional) 4. Optional Digital Audio ribbon cable/bracket 5. COM2 ribbon cable/bracket The mainboard is easily damaged by static electricity. Follow the precautions below while unpacking or installing the mainboard. 1. Do not remove the mainboard from its original package until you are ready to install it. 2. Frequently ground yourself to discharge any static electric charge that may build up in your body while working on installation and/or configuration. For example, you may ground yourself by grasping an unpainted portion of the systems metal chassis. 3. Remove the mainboard from its anti-static packaging and place it on a grounded surface, component side up. 4. Handle the mainboard by its edges or by the mounting bracket to avoid touching its components. 5. Check the mainboard for damage. If any integrated circuit appears loose, press carefully to seat it firmly in its socket. 6. Do not apply power if the mainboard appears damaged. If there is damage to the board contact your dealer immediately.

Chapter 2

Hardware Configuration
Before you install the mainboard into the system chassis, you may find it convenient to first configure the mainboards hardware. This chapter describes how to set jumpers and install memory modules, and where to attach components, however, the CMOS jumper is set on the Clear position when this mainboard is shipped and you need to set it to the Normal position in order for the mainboard perform properly. Warning: Set JP6 to Normal position before setting other jumpers or memory modules. This mainboard will not function properly if you fail to do so.

CPU Installation

CPU Speed Setting
This mainboard provides CPU Plug and Play technology, so that there is no need to do the CPU jumper setting. Enter the BIOS Setup and select CPU Plug and Play Setup. Choose the correct CPU speed to match your CPU installed. However, if you need to change a CPU, follow the below steps: 1. Power off system and unplug the power core. 2. Install a new CPU to Socket7. 3. Clear CMOS RAM (see Jumper Settings) or hold down the <Insert> key then power on the system. 4. After power on the system, then enter the BIOS Setup section to set the new CPU speed. Note: If the CPU speed is set incorrectly and fails to boot up the system, then repeat steps 1, 3, 4 again.

Memory Installation

The mainboard lets you add up to 768MB of system memory through 3 DIMM sockets on the board, that is divided into 3 banks: Bank 0, Bank 1, and Bank 2, which supports the following memory configurations. Bank Memory Module Bank 0 DIMM1 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB Bank 1 DIMM2 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB Bank 2 DIMM3 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB Total System Memory = Bank 0 + Bank 1 + Bank 2 Notes: 1. Supports only 3.3V SDRAM DIMM modules. 2. The SDRAM must be installed in DIMM1 first, if onboard VGA is being used.

Jumper Settings

JP6 - CMOS RAM Clear Selector
The battery on this mainboard is designed to retain the system configuration in CMOS RAM. In order to save the life of the battery, this jumper is set to "Clear CMOS" position when this board is shipped, therefore you need to set this jumper to "Normal" position before setting other system configuration.

Description Clear CMOS

(while shipping)

Normal

Note: 1. Make sure this jumper is set to Normal mode before use. 2. Once you need to clear the CMOS, make sure your system is truned off and the power core is unplugged.
ATX Functions & Connectors

Notice for PCI Sound application
1. Before you install the PCI Sound drivers, make sure your Operating System has been installed, otherwise the PCI Sound Pro might be detect as "Other Device" by the device manager of your OS. 2. After the drivers install, if you wants to use Software Wave-Table drivers as MIDI output device, select MULTIMEDIA icon within CONTROL PANEL. Select 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 within PCI Sound drivers, which gives you control over all audio functions through a user interface as simple to use a home stereo system, we recommended you to use the System Mixer within Audio Rack to control the volume, recording device select and recording gain. 4. If you using devices that use Midi port as the control interface, you need to select MULTIMEDIA icon within CONTROL PANEL. Select MIDI page, and click on "CM8338 MPU-401"(Win98) or "CMI8338/C3DX PCI Audio External MIDI port"(Win95) then click "OK" to confirm. 5. See details of PCI Sound manual within the CD attached with the mainboard.

The 4 Speakers System

Onboard Sound provides 2 wave channels (front/rear), known as the 4 speakers system. When application programs via DirectSound 3D or A3D interface locate the sound sources to the listener's back, the two rear speakers will work to enhance the rear audio positional effect, so as to complement the insufficiency of using only two front speakers to emulate the audio effect. The following is the hardware installation and the software setups: 1. The speaker installation. Connect the front pair speakers to the Line-out jack on the Sound port, and then connect rear pair speakers to Line-in/ Rear jack. The original Line-in can be moved to Aux-in. 2. The positions of the speakers Put your speakers the way the following picture suggests, so as to avail yourself to the best audio result. 3. The mixer setup When user was setup the PCI Audio Application, there is a 4 speakers option in the Volume Control of the Mixer, click 4 SPK icon to enable this option, it means the rear speakers are connected to Line-in/Rear jack. When Line-in/Rear jack is connected to other external Line-in sources, please DO NOT enable this option in order to avoid hardware conflicts. Regarding rear speaker option, you can turn on/off the output of the back speakers, and adjust the volume of speakers to the same volume. 4. The demo Execute the "Helicopter" demo within the C3D HRTF Positional Audio Demos of the PCI Audio Application. When the helicopter flies behind you, the rear speakers will work.

BIOS Setup
This chapter explains how to configure the mainboards BIOS setup program. The setup program provided with the mainboard is the BIOS from AMI. After you have configured the mainboard and have assembled the components, turn on the computer and run the software setup to ensure that the system information is correct. The software setup of the system board is achieved through Basic Input-Output System (BIOS) programming. You use the BIOS setup program to tell the operating system what type of devices are connected to your system board. The system setup is also called CMOS setup. Normally, you need to run system setup if either the hardware is not identical with information contained in the CMOS RAM, or if the CMOS RAM has lost power. Note: Hold down the <End> key then power on to reboot the system when installing newer BIOS into this mainboard.

Entering BIOS Setup

To enter the BIOS Setup program: 1. Turn on or reboot the system. A screen appears with a series of diagnostic checks. 2. When Hit <DEL> if you want to run SETUP appears, press the <DEL> key to enter the BIOS setup program. The following screen appears:
