Introduction
Product Description
The IB804 PCI-104+ SBC a small footprint single board computer that
is configured with the Intel Atom processor N270 at 1.6GHz, FSB533
and the Mobile Intel 945GSE Express Chipset with the ICH7M.
This PCI-104+ board provides greater flexibility for developers of
embedded computing solutions. It is ideally suited for rugged and
compact designs as in Internet devices and applications in automation,
industrial control, data acquisition, thin client and other embedded PC
applications.
IB804 features the Intel's Graphics Media Accelerator 950 core, making
it compatible with Windows Vista Premium, and support display
interfaces including VGA CRT and single channel 18-bit LVDS
displays. One DDR2 SO-DIMM on board implements up to 1GB of
system memory. One Gigabit LAN, with Intel 82574L controller, is also
available.
Advanced connectivity and expansion interfaces are provided by one
IDE, two RS-232 serial ports and four USB 2.0 high-speed ports.
Remarks: In installing the PC/104 Plus CPU board into a chassis, it is
recommended that the CPU board be placed on the topmost level of the
PC/104 board layers. The chassis environment should be designed in
such a way that there is good airflow to ventilate the system.

Installations
This section provides information on how to use the jumpers and
connectors on the IB804 in order to set up a workable system. The topics
covered are:
Installing the Memory (SODIMM) ....................................................... 6
Jumpers and Connector on IB804 ......................................................... 7

INSTALLATIONS
Installing the Memory (SODIMM)
The IB804 CPU board supports one DDR2 memory socket that can
support up to 1GB memory, DDR2 400/533 (w/o ECC function).
Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR2 module so that the key of the DDR2 module aligns
with that on the memory slot. Insert the module into the socket at a
slight angle (approximately 30 degrees). Note that the socket and
module are both keyed, which means that the module can be installed
only in one direction.
2. To seat the memory module into the socket, apply firm and even
pressure to each end of the module until you feel it slip down into the
socket.
3. With the module properly seated in the socket, rotate the module
downward. Continue pressing downward until the clips at each end
lock into position.
4. To remove the DDR2 module, press the clips with both hands.
