AAEON, a leading Industrial PC manufacturer, announces the
debut of a high performance full-size Single Board Computer, the
FSB-B75G.
latest Intel
AAEON has developed this full-size SBC based on the
®
B75 chipset and the Intel® 3rd generation Core™i7/i5/i3
LGA 1155 processor, to fulfill the increasing demands of multi-core
processing.
In a PICMG 1.0 form factor, the FSB-B75G system host board t akes
®
full advantage of the Intel
B75 chipset for enhanced system
performance and generous expansion capabilities. Considerable
bandwidth is available with point-to-point serial PCI-Express via
[x16] and [x4] interfaces. Maximizing the available PCI-Express
channels offers the greatest flexibility to today’ s d ema nding I/O
requirements. Two DIMM slots of dual-channel DDR3 1333/1600
sockets provide ample memory bus bandwidth for demanding
applications. The FSB-B75G has been designed for users that
require high performance and reliability for critical applications.

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

2.5 List of Connectors
The board has a number of connectors that allow you to configure
your system to suit your application. The table below shows the
function of each board's connectors:
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 Cl osed 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.

Full-size SBC FSB-B75G
3.1 System Test and Iinitialization
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.
System configuration verification
These routines check the current system configuration stored in the
CMOS memory and BIOS NVRAM. If system configuration is not
found or system configuration data error is detected, system will
load optimized default and re-boot with this default system
configuration automatically.
There are four situations in which you will need to setup system
configuration:
1. You are starting your system for the first time
2. You have changed the hardware att ached to your system
3. The system configuration is reset by Clear-CMOS jumper
4. The CMOS memory has lost power and the configuration
information has been erased.
The FSB-B75G 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.
Chapter 3 AMI BIOS Setup 3-2

3.2 AMI BIOS Setup
AMI BIOS ROM has a built-in Setup program that allows users to
modify the basic system configuration. This type of information is
stored in battery-backed CMOS RAM and BIOS NVRAM so that it
retains the Setup information when the power is turned off.
Entering Setup
Power on the computer and press <Del>or <F2> immediately. This
will allow you to enter Setup.

To enter the W83627DHG 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).
