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 parts have been shipped.
1 x Intel G41 Micro ATX Main board
1 x CD-ROM containing the following:
User’s Manual in PDF file

1.4 Manual Objectives
This manual describes in detail the Avalue Technology ERX-G41 motherboard.
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 interface
with ERX-G41 series 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 concerning this manual and want to inform
us of these, please contact our Customer Service department with the relevant details.

2.2 Installation Procedure
This chapter explains you the instructions of how to setup your system.
1. Turn off the power supply.
2. Insert the DIMM module (be careful with the orientation).
3. Insert all external cables for hard disk, floppy, keyboard, mouse, USB etc. except for flat
panel. A CRT monitor must be connected in order to change CMOS settings to support
flat panel.
4. Connect power supply to the board via the ATXPWR.
5. Turn on the power.
6. Enter the BIOS setup by pressing the delete key during boot up. Use the “LOAD BIOS
DEFAULTS” feature. The Integrated Peripheral Setup and the Standard CMOS Setup
Window must be entered and configured correctly to match the particular system
configuration.
7. If TFT panel display is to be utilized, make sure the panel voltage is correctly set before
connecting the display cable and turning on the power.
Note: Make sure the heat sink and the CPU top surface are in total contact to
avoid CPU overheating problem that would cause the system to hang or
unstable

2.2.1 Main Memory
ERX-G41 provides 2 x 240 pin DDR DIMM sockets supports DDRII memories 667/800
MHz up to 4GB
Make sure to unplug the power supply before adding or removing DIMMs or
other system components. Failure to do so may cause severe damage to
both the board and the components.

Locate the DIMM socket on the board.
Hold two edges of the DIMM module carefully. Keep away from touching its
connectors.
Align the notch key on the module with the rib on the slot.
Firmly press the module into the socket, it will automatically snap into the mounting
notch. Do not force the DIMM module in with extra force as the DIMM module only fit
in one direction.
To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
Note:
(1) Please do not change any DDR2 SDRAM parameter in BIOS setup to increase
your system’s performance without acquiring technical information in advance.
(2) Static electricity can damage the electronic components of the computer or
optional boards. Before starting these procedures, ensure that you are
discharged of static electricity by touching a grounded metal object briefly.

2.3 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.
