Product Warranty (2 years)
Advantech 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 pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, 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
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed 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.

4. For plug-in equipment, the power outlet socket must be located near the equip-
ment and must be easily accessible.
5. Keep this equipment away from humidity.
6. Put this equipment on a reliable surface during installation. Dropping it or letting
it fall may cause damage.
7. The openings on the enclosure are for air convection. Protect the equipment
from overheating. DO NOT COVER THE OPENINGS.
8. Make sure the voltage of the power source is correct before connecting the
equipment to the power outlet.
9. Position the power cord so that people cannot step on it. Do not place anything
over the power cord.
10. All cautions and warnings on the equipment should be noted.
11. If the equipment is not used for a long time, disconnect it from the power source
to avoid damage by transient overvoltage.
12. Never pour any liquid into an opening. This may cause fire or electrical shock.
13. Never open the equipment. For safety reasons, the equipment should be
opened only by qualified service personnel.
14. If one of the following situations arises, get the equipment checked by service
personnel:
–The power cord or plug is damaged.
–Liquid has penetrated into the equipment.
–The equipment has been exposed to moisture.
–The equipment does not work well, or you cannot get it to work according to
the user's manual.
–The equipment has been dropped and damaged.
–The equipment has obvious signs of breakage.
Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec-
tronic components.

SOM-6765 User Manual 2
1.1 Introduction
SOM-6765 is an embedded COM-Express Compact COM.0 R2.0 Type 2 CPU mod-
ule that fully complies with the PCI Industrial Computer Manufactures PICMG COM
Express standard. The new CPU module supports Intel N2600 and D2700 proces-
sors with NM10 chipset which supports Intel Embedded GFX Core, MPEG2 Decode
in HW, PCI Express and SATA interfaces. In a basic form factor of 95mm x 95mm,
the SOM-6765 provides a scalable high performance and easy to integrate solution
for customers’ applications by utilizing a plug-in CPU module on an application-spe-
cific customer solution board. The SOM-6765 with advanced I/O capacity incorpo-
rates serial differential signaling technologies such as PCI Express, Serial ATA, USB
2.0, LVDS, and HD Audio interfaces. SOM-6765 offers customers more choices for
their own applications needing higher computing speeds while maintaining a com-
pact form factor.
SOM-6765 complies with the "Green Function" standard and supports Doze, Standby
and Suspend modes. The small size (95 mm x 95 mm) and use of one high capacity
connector based on the proven COM-Express Compact form factor, allow the mod-
ules to be easily and securely mounted onto a customized solution board or our stan-
dard SOM-DB5700 development board.

AMIBIOS has been integrated into many motherboards for over a decade. With the
AMIBIOS Setup program, users can modify BIOS settings and control the various
system features. This chapter describes the basic navigation of the SOM-6765 BIOS
setup screens.
Figure 3.1 Setup program initial screen
AMI's BIOS ROM has a built-in Setup program that allows users to modify the basic
system configuration. This information is stored in flash ROM so it retains the Setup
information when the power is turned off.
3.1 Entering Setup
Turn on the computer and then press <F2> or <DEL> to enter Setup menu.
