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.
Always note that improper disassembling action could cause damage to the
motherboard. We suggest not removing the heatsink without correct
instructions in any circumstance. If you really have to do this, please contact
us for further support.
1.2 Packing List

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 BIOS settings to support flat
panel.
4. Connect power supply to the board via the ATX Power.
5. Turn on the power.
6. Enter the BIOS setup by pressing the delete key during boot up. Use the "Save & Exit \
Restore Defaults" feature.
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.

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.
