Industrial Motherboard IMBA-880 Rev.B
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 Clo s ed 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.

3.1 CPU installation and motherboard handling
Note: When integrating a Pentium 4 processor-based system, be sure to take the
proper electrostatic discharge (ESD) precautions.
Caution: Please follow the steps below to ensure proper installation of your
processor. Failure to follow these instructions may result in damage to your CPU
and/or your motherboard.
Retention

lever
Protective Cover
Step 1: (Socket Preparation)
Note: Visually inspect to ensure that the socket protective cover is present and
securely fastened.
1. Opening the Socket:
Note: Hold corner of the load plate while opening and closing the load
lever. This will prevent the bounce back of the load plate which can
cause bent contacts.
a. Disengage the Load Lever by pressing down and
out on the hook allowing the lever to clear the
Retention Tab and rotate to the fully open position.
Chapter 3 CPU, Heatsink and Fan Installation 3-2
Industrial Motherboard IMBA-880 Rev.B
b. Rotate Load Plate to fully open position
.
c. Remove the Protective Cover
Caution: Do not touch the Socket Contacts. This may result in damage to the
contacts.
Note: Visually inspect the contact area for bent contacts and foreign material.
Chapter 3 CPU, Heatsink and Fan Installation 3-3
Industrial Motherboard IMBA-880 Rev.B
Step 2: (Processor Handling)
Note: Handle Processor by substrate edges only.
Caution: Do not touch processor contacts at any time
a. Remove processor from shipping media by
grasping substrate edges only
b. Visually inspect the processor gold pad array for
presence of foreign material. If foreign material is
present the pads may be wiped clean with a
lint-free cloth and isopropyl alcohol.
c. Locate the connector 1 indicator and the two
orientation notches. (See photo)

Step 3: (Positioning the CPU into socket)
a. Grasp the processor with your thumb and
forefinger on the edges with the orientation notches.
The socket has cut-outs for your fingers when
handled in this orientation.
b. Carefully place the CPU into the socket with a
purely vertical motion.
c. Verify that the CPU is in the socket body and
properly mated to the orientation keys.

Chapter 4 Award BIOS Setup 4-1
Industrial Motherboard IMBA-880 Rev.B
4.1 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. Non-fatal error messages
usually appear on the screen along with the following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue the boot
up sequence.
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 hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The IMBA-880 Rev.B 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.

To enter the W83627EHG 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).
