ESD Precautions

Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:

 Do not remove boards or integrated circuits from their anti-static

packaging until you are ready to install them.

 Before holding the board or integrated circuit, touch an unpainted

portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.

 Wear a wrist-grounding strap, available from most electronic

component stores, when handling boards and components.

Introduction

The ETM831 Series is a finest embedded ETX system-on-a-module
in the market, which makes a generic interface to connect the module
to peripherals such as hard disk, mouse, and display. It supports

Intel

®

Atom N270 processor with 533MHz FSB (Front Side Bus).

The board integrates Intel

®

945GSE and ICH7M chipsets that support
one 200-pin DDR2-400/533 SDRAM with maximum up to 2GB system
memory capacity. It makes the all-in-one single module together with
excellent Multiple I/O, dual independent display CRT and LVDS LCD
through ETX connector, Fast Ethernet and 5.1 Channel HD Codec
Audio. Through ETX connectors, it also provide one FDD/LPT port,
four PCI and one full ISA bus for expansion purpose, one PATA, two
SATA and four USB 2.0 ports for high speed peripherals. It can
achieve the best stability and reliability that makes your system
perform the most endurable operation in any critical environments.
The built-in Watchdog Timer has enhanced the system reliability that
achieves a unique feature to distinguish itself from other boards.

2.3 Heatspreader Installation

1. There is a protective plastic covering on the thermal pads. This
must be removed before the heatspreader can be mounted.
Each heatspreader is designed for a specific ETM module. The
thermal pads on the heatspreader are designed to make contact
with the necessary components on the ETM module. When
mounting the heatspreader you must make sure that the thermal
pads on the heatspreader make complete contact (no space
between thermal pad and component) with the corresponding
components on the ETM module. This is especially critical for
ETM modules that have higher CPU speeds (for example

1.0GHz or more) to ensure that the heatspreader acts as a
proper thermal interface for cooling solutions.

2. The two M2.5x8 screws and two M2.5x12 screws are used to

mount the heatspreader and ETM module assembly to the
baseboard. (see Figure 1)

3. If you have an additional thermal solution on the heatspreader,

please refer to the ETM831 thermal solu tion design guide (see
Figure 2) to design your thermal solution.

CHAPTER 4

AMI BIOS SETUP UTILITY

This chapter provides users with detailed description how to set up
basic system configuration through the AMIBIOS8 BIOS setup utility.

4.1 Starting

To enter the setup screens, follow the steps below:

1. Turn on the computer and press the <Del> key immediately.

2. After you press the <Delete> key, the main BIOS setup menu
displays. You can access the other setup screens from the main
BIOS setup menu, such as the Chipset and Power menus.

4.2 Navigation Keys

The BIOS setup/utility uses a key-based navigation system called hot
keys. Most of the BIOS setup utility hot keys can be used at any time
during the setup navigation process.
These keys include <F1>, <F10>, <Enter>, <ESC>, <Arrow> keys,
and so on.

Note Some of navigation keys differ from one screen to

another.

Å Left/Right

The Left and Right <Arrow> keys allow you to select
a setup screen.

ÇÈ Up/Down

The Up and Down <Arrow> keys allow you to select
a setup screen or sub-screen.

+− Plus/Minus

The Plus and Minus <Arrow> keys allow you to
change the field value of a particular setup item.

Tab

The <Tab> key allows you to select setup fields.

F1

The <F1> key allows you to display the General
Help screen.

F10

The <F10> key allows you to save any changes you
have made and exit Setup. Press the <F10> key to
save your changes.

Esc

The <Esc> key allows you to discard any changes
you have made and exit the Setup. Press the
<Esc> key to exit the setup without saving your
changes.

Enter

The <Enter> key allows you to display or change the
setup option listed for a particular setup item. The
<Enter> key can also allow you to display the setup
sub- screens.

4.3 Main Menu

When you first enter the Setup Utility, you will enter the Main setup
screen. You can always return to the Main setup screen by selecting
the Main tab. There are two Main Setup options. They are described
in this section. The Main BIOS Setup screen is shown below.

z System Time/Date

Use this option to change the system time and date. Highlight
System Time or System Date using the <Arrow> keys. Enter new
values through the keyboard. Press the <Tab> key or the
<Arrow> keys to move between fields. The date must be entered
