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

2.5 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.

Chapter 3 AMI BIOS Setup 3-1
ETX CPU Module ETX-LN
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 ETX-LN 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
ETX CPU Module ETX-LN
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

ETX CPU Module ETX-LN
(3) Exit the W83627DHG config Mode. Undesired result may
occur if the config Mode is not exited normally.
(1) Enter the W83627DHG config Mode
To enter the W83627DHG config Mode, two 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 two write operations to the Special Address port (2EH).
The different enter keys are provided to select configuration ports
(2Eh/2Fh) of the next step.
Address Port Data Port
87h,87h: 2Eh 2Fh
(2) Modify the Data of the Registers
All configuration registers can be accessed after entering the config
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 W83627DHG config Mode
The exit key is provided to select configuration ports (2Eh/2Fh) of
the next step.
