1.1 Introduction

AAEON, a leading embedded board manufacturer, is pleased to

announce the debut of their new generation COM Express Module-

COM-BT. The COM-BT is a cutting-edge product that provides high

performance and low power consumption in the embedded market.

COM-BT adopts the latest Intel® Celeron® J1900, N2930, N2807 and

Atom™ E3800 Series product family. The system memory deploys

with one DDR3L 1066/1333 MHz SODIMM up to 8 GB (4GB max for

E3815/E3825/N2807). In addition, Intel® I211 supports Gigabit

Ethernet that allows faster network connections. This model applies

four PCI-Express[x1] (one shared with Gigabit LAN). Moreover, two

SATA 3.0Gb/s are configured on the COM-BT. COM-BT also equips

USB2.0 x6, USB3.0 x1(combine USB2.0 x1) for flexible I/O

expansions.

The display of COM-BT supports up to two independent displays

simultaneously. This brand new COM Express Module is developed to

cater to the requirements of Automation, Medical, ticket machine,

transportation, gaming, KIOSK, and POS/POI applications.

Chapter 2 Quick Installation Guide 2-1

COM Express Module

C O M - BT

Always completely disconnect the power cord from your board whenever you are working on it. Do not make connections while the power is on, because a sudden rush of power can damage sensitive electronic components.

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

3.1 System Test and Initialization

These routines test and initialize board hardware. If the routines

encounter an error during the tests, you will either hear a few short

beeps or see an error message on the screen. There are two kinds

of errors: fatal and non-fatal. The system can usually continue the

boot up sequence with non-fatal errors.

System configuration verification

These routines check the current system configuration stored in the

CMOS memory and BIOS NVRAM. If system configuration is not

found or system configuration data error is detected, system will

load optimized default and re-boot with this default system

configuration automatically.

There are four situations in which you will need to setup system

configuration:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The system configuration is reset by Clear-CMOS jumper

4. The CMOS memory has lost power and the configuration

information has been erased.

The COM-BT CMOS memory has an integral lithium battery backup

for data retention. However, you will need to replace the complete

unit when it finally runs down.

3.2 AMI BIOS Setup

AMI BIOS ROM has a built-in Setup program that allows users to

modify the basic system configuration. This type of information is

stored in battery-backed CMOS RAM and BIOS NVRAM so that it

retains the Setup information when the power is turned off.

Entering Setup

Power on the computer and press <Del>or <F2> immediately. This

will allow you to enter Setup.

Main

Set the date, use tab to switch between date elements.

Advanced

Enable disable boot option for legacy network devices.

Chipset

Host bridge parameters.

Boot

Enables/disable quiet boot option.

Security

Set setup administrator password.

Save & Exit

Exit system setup after saving the changes.

You can install a Supervisor password, and if you install a supervisor password, you can then install a user password. A user password does not provide access to many of the features in the Setup utility.

If you highlight these items and press Enter, a dialog box appears which lets you enter a password. You can enter no more than six letters or numbers. Press Enter after you have typed in the password. A second dialog box asks you to retype the password for confirmation. Press Enter after you have retyped it correctly. The password is required at boot time, or when the user enters the Setup utility.
