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.

1.3 Special features
1.3.1 Product highlights
The Latest Processor Technology
The Intel® Atom™ processor is Intel's smallest processor, built with the world's smallest
transistors and manufactured on Intel's industry-leading 45nm Hi-k Metal Gate technology.
The Intel Atom processor was purpose-built for simple, affordable, netbooks and nettops.
Intel® Atom™ N270 Processor
The Intel® Atom™ processor N270, implemented in 45nm technology, is power-optimized
and delivers robust performance-per-watt for cost-effective embedded solutions. Featuring
extended lifecycle support, this processor offers an excellent solution for embedded market
segments such as digital signage, interactive clients (kiosks, point-of-sale terminals), thin
clients, digital security, residential gateways, print imaging, and commercial and industrial
control. The processor remains software compatible with previous 32-bit Intel® architecture
and complementary silicon.
Intel® 945GSE Chipset
The mobile Intel® 945GSE Express Chipset provides power-efficient graphics and rich I/O
capabilities for cost-effective embedded solutions. It features an integrated 32-bit 3D
graphics engine based on Intel® Graphics Media Accelerator 950 (Intel® GMA 950)
architecture, a 533 MHz front-side bus (FSB), single-channel 400/533 MHz DDR2 system
memory (SODIMM and/or memory down), and Intel® High Definition Audio¹interface.
The chipset consists of the Intel® 82945GSE Graphics Memory Controller Hub (GMCH)
and Intel® I/O Controller Hub 7-M (ICH7-M). It delivers outstanding system performance
and flexibility through high-bandwidth interfaces such as PCI Express,* PCI, Serial ATA,
and Hi-Speed USB 2.0 connectivity.
DDR2 memory support
The motherboard supports DDR2 memory which features data transfer rates of
1066/800/533 MHz to meet the higher bandwidth requirements of the latest 3D graphics,
multimedia, and Internet applications. The dual-channel DDR2 architecture doubles the
bandwidth of your system memory to boost system performance, eliminating bottlenecks
with peak bandwidths of up to 8.5 GB/s.
PCI Express™ interface
The motherboard fully supports PCI Express, the latest I/O interconnect technology that
speeds up the PCI bus. PCI Express features point‑to‑point serial interconnections
between devices and allows higher clockspeeds by carrying data in packets. This high

User’s Manual
EMX-945GSE Series User’s Manual

speed interface is software compatible with existing PCI specifications. See page 1-22 for
details.
Serial ATA technology
The motherboard supports the Serial ATA technology through the Serial ATA interfaces
and the Intel® ICH7 chipset. The SATA specification allows for thinner, more flexible cables
with lower pin count, reduced voltage requirement, and up to 300 MB/s data transfer rate.
S/PDIF digital sound ready
The motherboard supports the S/PDIF Out function through the S/PDIF interfaces at
mainboard. The S/PDIF technology turns your computer into a high-end entertainment
system with digital connectivity to powerful audio and speaker systems. See page 1-31 for
details.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASIC (integrated in the Winbond Super I/O) to
prevent overheating and damage. The system fan rotations per minute (RPM) is monitored
for timely failure detection. The ASIC monitors the voltage levels to ensure stable supply of
current for critical components.

1.4 Before you proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
Unplug the power cord from the wall socket before touching
any component.
Use a grounded wrist strap or touch a safely grounded object
or a metal object, such as the power supply case, before
handling components to avoid damaging them due to static
electricity
Hold components by the edges to avoid touching the ICs on
them.
Whenever you uninstall any component, place it on a
grounded antistatic pad or in the bag that came with the
component.
Before you install or remove any component, ensure that
the ATX power supply is switched off or the power cord is
detached from the power supply. Failure to do so may
cause severe damage to the motherboard, peripherals, and/or
components.
