Full-size SBC FSB- 9 45G
1.1 Introduction
AAEON announces a new full-size form factor Single Board
Computer (SBC) with PICMG 1.0 - FSB-945G, which is based on
the use of Intel® CoreTM 2 Duo / P4 /Celeron D processors.
FSB-945G utilizes Intel® LGA 775 CoreTM 2 Duo/ Pentium® 4 CPU
with high CPU core frequencies with the Front Side Bus (FSB)
running at 533 to 800MHz.
FSB-945G supports DDRII 400/533/667 system memory up to 4GB.
The VGA Controller of FSB-945G integrates Intel 945GC chipset
with core frequency up to 400MHz and integrates GMA950 2D/3D
graphics Accelerator to provide higher performance of graphic
processing. AAEON’s got Intel’s long-term supply commitment
and will guarantee product’s long-life cycle to our precious
customers.
In addition to the powerful computing engine, FSB-945G equips
with seven USB2.0 ports, one standard Mini-DIN PS/2 keyboard &
mouse connector, one floppy device. Moreover, it also supports
four SATA II and one IDE. These versatile expansion interfaces
bring FSB-945G a great flexibility to serve different application
demands. Furthermore, its huge capacity and excellent
compatibility are also ideal for system integrators for system

Notice:
Full-size SBC FSB-945G
2.1 Safety Precautions
Always completely disconnect the power cord
from your board whenever you are working on
it. Do not make connections while the power is
on, because a sudden rush of power can
damage sensitive electronic components.
Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. 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

2.6 Setting Jumpers
You configure your card 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 (oft en 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 pins 1 and 2 or 2 and 3.

Open Closed Closed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales
representative before you make any change.
Generally, you simply need a standard cable to make most
connections.

Chapter 3 Award BIOS Setup 3-1
Full-size SBC FSB- 945G
3.1 System Test and Initialization
These routines test and initialize board hardware. If the
routines encounter an error during the tests, you will either
hear a few short beeps or see an error message on the
screen. There are two kinds of errors: fatal and non-fatal. The
system can usually continue the boot up sequence with
non-fatal errors. Non -fatal error messages usually appear on
the screen along with the following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue
the boot up sequence.
System configuration verification
These routines check the current system configuration
against the values stored in the CMOS memory. If they do
not match, the program outputs an error messag e. You will
then need to run the BIOS setup program to set the
configuration information in memory.
There are three situations in which you will need to change
the CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The FSB-945G CMOS memory has an integral lithium
battery backup for data retention. However, you will need to
replace the complete unit when it finally runs down.

(3) Exit the W83627EHG config Mode. Undesired result may
occur if the config Mode is not exited normally.
(1) Enter the W83627EHG config Mode
To enter the W83627EHG config Mode, two special I/O write
operations are to be performed during Wait for Key state. To
ensure the initial state of the key-check logic, it is necessary to
perform two write operations to the Special Address port (2EH).
The different enter keys are provided to select configuration ports
(2Eh/2Fh) of the next step.

(2) Modify the Data of the Registers
All configuration registers can be accessed after entering the config
Mode. Before accessing a selected register, the content of Index
07h must be changed to the LDN to which the register belongs,
except some Global registers.
(3) Exit the W83627EHG config Mode
The exit key is provided to select configuration ports (2Eh/2Fh) of
