Product Warranty
Avalue warrants to you, the original purchaser, that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Avalue, or which have been subject to
misuse, abuse, accident or improper installation. Avalue assumes no liability under the
terms of this warranty as a consequence of such events. Because of Avalue’s high
quality-control standards and rigorous testing, most of our customers never need to use our
repair service. If any of Avalue’s products is defective, it will be repaired or replaced at no
charge during the warranty period. For out-of-warranty repairs, you will be billed according
to the cost of replacement materials, service time, and freight. Please consult your dealer
for more details. If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example,
CPU type and speed, Avalue’s products model name, hardware & BIOS
revision number, other hardware and software used, etc.) Note anything
abnormal and list any on-screen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information available.
3. If your product is diagnosed as defective, obtain an RMA (return material
authorization) number from your dealer. This allows us to process your good
return more quickly.
4. Carefully pack the defective product, a complete Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales
receipt) in a shippable container. A product returned without proof of the
purchase date is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it
prepaid to your dealer.

1. Getting Started
1.1 Safety Precautions
Warning!
Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should
open the PC chassis.
Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution,
use a grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded
bag when they are not in the chassis.
1.2 Packing List
Before you begin installing your single board, please make sure that the
following materials have been shipped:
1 x EAX-C236KP motherboard
2 x SATA cable
1 x I/O Shield

1.4 Manual Objectives
This manual describes in details Avalue Technology EAX-C236KP Single Board.
We have tried to include as much information as possible but we have not duplicated
information that is provided in the standard IBM Technical References, unless it proved to
be necessary to aid in the understanding of this board.
We strongly recommend that you study this manual carefully before attempting to set up
EAX-C236KP or change the standard configurations. Whilst all the necessary information is
available in this manual we would recommend that unless you are confident, you contact
your supplier for guidance.
Please be aware that it is possible to create configurations within the CMOS RAM that
make booting impossible. If this should happen, clear the CMOS settings, (see the
description of the Jumper Settings for details).
If you have any suggestions or find any errors regarding this manual and want to inform us
of these, please contact our Customer Service department with the relevant details.

2.2 Jumper and Connector List
You can configure your board 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 two pins.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
If you have any doubts about the best hardware configuration for your application, contact
your local distributor or sales representative before you make any changes.
The following tables list the function of each of the board’s jumpers and connectors.
