A Message to the Customer
AAEON Customer Services
Each and every AAEON product is built to the most exacting
specifications to ensure reliable performance in the harsh and
demanding conditions typical of industrial environments. Whether
your new AAEON equipment is destined for the laboratory or the
factory floor, you can be assured that your product will provide the
reliability and ease of operation for which the name AAEON has
come to be known.
Your satisfaction is our primary concern. Here is a guide to
AAEON’s customer services. To ensure you get the full benefit of
our services, please follow the instructions below carefully.
Technical Support
We want you to get the maximum performance from your products.
So if you run into technical difficulties, we are here to help. For the
most frequently asked questions, you can easily find answers in
your product documentation. These answers are normally a lot
more detailed than the ones we can give over the phone.
So please consult this manual first. If you still cannot find the
answer, gather all the information or questions that apply to your
problem, and with the product close at hand, call your dealer. Our
dealers are well trained and ready to give you the support you need
to get the most from your AAEON products. In fact, most problems
reported are minor and are able to be easily solved over the phone.
In addition, free technical support is available from AAEON
engineers every business day. We are always ready to give advice
on application requirements or specific information on the
installation and operation of any of our products.

Product Warranty
AAEON warrants to you, the original purchaser, that each of its
products will be free from defects in materials and workmanship for
one year 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 autho-
rized by AAEON, or which have been subject to misuse, abuse,
accident or improper installation. AAEON assumes no liability
under the terms of this warranty as a consequence of such events.
Because of AAEON’s high quality-control standards and rigorous
testing, most of our customers never need to use our repair
service. If an AAEON product 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, type of PC, CPU speed, AAEON products used,
other hardware and software used, etc.) Note anything abnor-
mal 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 readily 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 return more quickly.
4. Carefully pack the defective product, a fully-completed Repair
and Replacement Order Card and a photocopy proof of pur-
chase 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.

Initial inspection
Before you begin installing your card, please make sure that the
following materials have been shipped:
• 1 SBC-775Pentium®II single board computer
• 1 Pentium II CPU and cooling fan (optional)
• 1 OBS temperature sensor
• 1 Quick Installation Guide
• 1 supporting CD-ROM
• 2disks, for OBS Win95 drivers
• 1 FDD cable
• 1 EIDE HDD cables
• 1 printer cable
• 1 ivory cable for keyboard and mouse
• 1 ATX-to-PS/2 power cable
• 1 Pentium II CPU retention module
If any of these items are missing or damaged, contact your
distributor or sales representative immediately.
We have carefully inspected the SBC-775 mechanically and
electrically before shipment. It should be free of marks and scratches
and in perfect working order upon receipt.
As you unpack the SBC-775, check it for signs of shipping damage.
(For example, damaged box, scratches, dents, etc.) If it is damaged or it
fails to meet the specifications, notify our service department or your
local sales representative immediately. Also notify the carrier. Retain
the shipping carton and packing material for inspection by the carrier.
After inspection, we will make arrangements to repair or replace the
unit.
Caution! Alwaysground yourselfto removeany staticcharge
beforetouching theCPU card. Modernelectronic
devices are very sensitive to static electric charges.
Try to use a grounding wrist strap at all times. Place
all electronic components on a static-dissipative
surface or in a static-shielded bag when they are not
in the chassis.

Introduction
The SBC-775 industrial grade CPU card uses Intel's highly
acclaimed Pentium®II processor and Intel 440LX PCI chipset. The
card works with standard ISA or PCI/ISA-bus passive backplanes.
The CPU provides 512 KB on-chip L2 cache, eliminating the need for
external SRAM chips. It has two PCI EIDE interfaces (for up to four
devices), and an FDD interface (for up to two devices). Other features
include two RS-232 serial ports (16C550 UARTs with 16-byte FIFO
or compatible), one enhanced parallel port (supports EPP/ECP), and
support two USB (Universal Serial Bus) ports. The PCI BUS Master
IDE controller supports Ultra DMA/33 operation. This provides data
transfer rates of over 33 MB/sec, and allows drive capacities up to
8.4 GB. System BIOS supports boot-up from an IDE CD-ROM.
A backup of CMOS data is stored in the Flash memory, which
protects data even after a battery failure. Also included is a 63-level
watchdog timer, which resets the CPU or generates an interrupt if a
program cannot be executed normally. This enables reliable operation
in unattended environments.
