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
surge. 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.
Always note that improper disassembling could damage to the
motherboard. We suggest not to, in any circumstance remove the heatsink
without the correct instructions. If you really have to do it, please contact us
for further support.
1.2 Packing List
Before you begin installing your single board, please make sure that the
following items have been shipped:
z1 x EAX-785E ATX Main Board
z2 x SATA cable kit(SATA/power)
z1 x COM 9P Cable W/O Bracket PH:2.00mm
z1 x DRIVER CD (CD-R) without printed LOGO

1.4 Manual Objectives
This manual describes in detail the Avalue Technology EAX-785E Motherboard 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 interface
with EAX-785E 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
EAX-785E provides 4 x 240-pin DDR3 DIMM, max. up to 8GB DDR3 800/1066/1333 with
ECC support.
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 SODIMM socket on the board.
•Hold two edges of the SODIMM module carefully. Keep away of touching its
connectors.
•Align the notch key on the module with the rib on the slot.
•Firmly press the module into the socket which automatically snaps into the mounting
notch. Do not force the SODIMM module in with extra force as the SODIMM module
only fits in one direction.
•To remove the SODIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the SODIMM module.
Note:
(1) Please do not change any DDR3 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 briefly touching a grounded metal object.

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.
