2.1 Safety Precautions

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

2.6 Setting Jumpers

You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by a
plastic cover) that slides over the pins to connect them. To “close” a
jumper you connect the pins with the clip.

To “open” a jumper you remove the clip. Sometimes a jumper will have
three pins, labeled 1, 2 and 3. In this case you would connect either
pins 1 and 2 or 2 and 3.

Open Closed Closed 2-3

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 change.

Generally, you simply need a standard cable to make most
connections.

Mini-ITX EMB-LN8T

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 against the
values stored in the CMOS memory. If they do not match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in memory.

There are three situations in which you will need to change the
CMOS settings:

1. You are starting your system for the first time

2. You have changed the h ardware attached to your system

3. The CMOS memory has lost power and the configuration

information has been erased.

The EMB-LN8T 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.

Chapter 3 AMI BIOS Setup 3-2

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 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.

A.1 Programming

EMB-LN8T utilizes ITE 8712 chipset as its watchdog timer
controller.

Below are the procedures to complete its configuration and the
AAEON intial watchdog timer program is also attached based on
which you can develop customized program to fit your application.

Configuring Sequence Description

After the hardware reset or power-on reset, the ITE 8712 enters the
normal mode with all logical devices disabled except KBC. The
initial state (enable bit ) of this logical device (KBC) is determined
by the state of pin 121 (DTR1#) at the falling edge of the system
reset during power-on reset.

Appendix A Programming the Wa tchdog Timer A-2

Mini-ITX EMB-LN8T

There are three steps to complete the configuration setup: (1) Enter
the MB PnP Mode; (2) Modify the data of configuration registers; (3)
Exit the MB PnP Mode. Undesired result may occur if the MB PnP
Mode is not exited normally.

(1) Enter the MB PnP Mode

To enter the MB PnP Mode, four special I/O write operations are to
be performed during Wait for Key state. To ensure the initial state of
the key-check logic, it is necessary to perform four write ope rations
to the Special Address port (2EH). Two different enter keys are
provided to select configuration ports (2Eh/2Fh) of the next step.

(2) Modify the Data of the Registers

All configuration registers can be accessed after entering the MB
PnP Mode. Before accessing a selected register, the content of
Index 07h must be changed to the LDN to which the register
belongs, except some Global registers.

(3) Exit the MB PnP Mode

Set bit 1 of the configure control register (Index=02h) to 1 to exit the
MB PnP Mode.

WatchDog Timer Configuration Registers

Configure Control (Index=02h)

This register is write only. Its values are not sticky; that is to say, a
hardware reset will automatically clear the bits, and does not
require the software to clear them.
