Safety Precautions

 Warning!

Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections
while the power is on. Sensitive electronic components can be
damaged by sudden power surges. Only experienced electronics
personnel should open the PC chassis.

 Caution!

Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all electronic components
in a static-dissipative surface or static-shielded bag when they are
not in the chassis.

Chapter 2 Installations

2.1 Memory Module（SODIMM）Installation

The A831 SBC provides one 200-pin SODIMM slot. The socket supports up to 1GB
DDR 400 SDRAM. When installing the Memory device, please follow the steps
below：

Step.1. Firmly insert the SODIMM at an angle into its slot. Align the SODIMM on the
slot such that the notch on the SODIMM matches the break on the slot.

Step.2. Press downwards on SODIMM until the retaining clips at both ends fully snap
back in place and the SODIMM is properly seated.

¾

Caution!

The SODIMM only fits in one correct orientation. It will cause
permanent damage to the development board and the SODIMM if
the SODIMM is forced into the slot at the incorrect orientation.

2.2 I/O Equipment Installation

2.2.1 PS/2 Keyboard and PS/2 Mouse

The A831 SBC provides a Mini-DIN connector supports PS/2 interface. Mini-DIN
connector supports Keyboard and Mouse through Y cable. Please plug keyboard or
mouse directly with Y cable. In other cases, especially in embedded applications, a
mouse is not used. Therefore, the BIOS standard setup menu allows you to select*
“All, But Keyboard” under the “Halt On”. This allows no-keyboard operation in
embedded system applications without the system halting under POST.

2.2.2 Audio function

The AC’97 capabilities are provided by a Realtek ALC203 chip supporting digital
audio outputs. The onboard ALC203 is a 20-bit DAC and 18-bit ADC supporting
full-duplex AC’97 2.3 compatible stereo audio CODEC for multimedia, including
host/soft audio based designs. The audio interface includes two jacks: microphone-in
and line-out.

2.2.3 Serial COM ports

One RS-232 ports with 16C550 UART (or compatible) with 16-byte FIFO buffer.
Three optional COM ports support RS-232. When an optional touch-screen is ordered
with PPC, serial com port can connect to a serial or an optional touch-screen. One
optional COM port supports RS232/422/485 choice through jumper setting.

2.2.4 Ethernet interface

The Motherboard is equipped with dual Realtek RTL8100C or optional dual Realtek
RTL8110SC Gigabit Ethernet chipset which is fully compliant with the PCI 10/100
Mbps Ethernet protocol compatible. It is supported by major network operating
systems. The Ethernet port provides a standard RJ-45 jack.

2.2.5 USB ports

Four USB (Two is optional) device may be connected to the system though an adapter
cable. Various adapters may come with USB ports. USB usually connect the external
system to the system. The USB ports support hot plug-in connection. Whatever, you
should install the device driver before you use the device.

2.2.6 External VGA

The Motherboard has one VGA port that can be connected to an external CRT/ LCD
monitor. Use VGA cable to connect to an external CRT / LCD monitor, and connect
the power cable to the outlet. VGA connector is a standard 15-pin D-SUB connector.

2.4 Jumper Setting 2.4 Jumper Setting

A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.

Chapter 3 Award BIOS SETUP

3.1 Starting Setup

AwardBIOS™ has a built-in setup program that allows users to modify the basic
system configuration. The information is stored in battery-backed Flash so that it
retains the setup information even if the system power is turned off.

Note:

Values for the various setup items that appear on your own screen (including
default values) may not be the same as the values shown on the screen figures in
this chapter. This is because the BIOS is revised and updated from time to time.
If in doubt, check Winmate website for the latest BIOS versions and related
information.

Chapter 4 SATA Driver Installation

SATA interface is a new, fast, disk drive standard, but Windows doesn't come with
device drivers. Without the proper drivers installed, your system can not recognize a
SATA drive.

4.1 Get the right Drivers

The first step is to get the right drivers. SATA drivers generally place on your driver
CD that comes with your A831 board. However you also can check the
manufacturer’s web site and download the latest versions of the drivers.

4.2 Installing SATA Drivers

Windows expects you to install the SATA drivers from a floppy. Therefore, load the
SATA drivers onto a floppy disk and be connected with an USB external floppy disk
driver. If this is a new system, you will be installing a fresh copy of Windows XP.

During the initial portion of the Windows Set-Up, there will be a point where a
message flashes on the screen telling you to press

F6. The message scrolls past
quickly, so be alert for it. Pressing F6 will give you the opportunity to install your new
drivers.

embedded memory. With state-of-the-art DSP technology and mixed-mode signal
technology, it offers high-speed transmission over CAT 5 UTP or CAT 3 UTP
(10Mbps only) cable. Functions such as Crossover Detection & Auto-Correction,
polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation,
timing recovery, and error correction are implemented to provide robust transmission
and reception capability at high speeds.

The Ethernet port provides an On-board standard RJ-45 connector. The device
supports the PCI 10/100Mbps Ethernet interface supports for host communications
with power management, and is compliant with the IEEE 802.3 specification for
10/100Mbps.

Chapter 8 AUDIO Driver Installation

8.1 Introduction

The Motherboard is equipped with the ALC203 is a 20-bit DAC and 18-bit ADC
full-duplex AC'97 2.3 compatible stereo audio CODEC designed for PC multimedia
systems, including host/soft audio, and AMR/CNR based designs.

The ALC203 incorporates proprietary converter technology to achieve a high SNR
(greater than 100 dB), sensing logics for device reporting, and a Universal Audio
Jack® for improved user convenience. The ALC203 AC'97 CODEC supports multiple
CODEC extensions with independent variable sampling rates and built-in 3D effects.
The ALC203 CODEC provides two pairs of stereo outputs with independent volume
controls, a mono output, multiple stereo and mono inputs, along with flexible mixing,
gain, and mute functions to provide a complete integrated audio solution for PCs.

The circuitry of the ALC203 CODEC operates from a 3.3V digital and 3.3V/5V
analog power supply with EAPD (External Amplifier Power Down) control for use in
notebook and PC applications. The ALC203 integrates a 50mW/20Ohm headset audio
amplifier into the CODEC, saving BOM costs. The ALC203 also supports the S/PDIF
out function (complies with AC'97 2.3) that offers easy connection of PCs to
consumer electronic products, such as AC3 decoders/speakers and mini disk devices.

8.2 Installation of Audio Driver

The users must make sure which operating system you are using in the Motherboard
before installing the Audio drivers. Follow the steps below to complete the installation
of the Realtek ALC203 AC97 Audio drivers. You will quickly complete the
installation.
Follow the steps below to install the Realtek AC97 Codec Audio Drivers.
