INTRODUCTION
Introduction
Product Description
The ET900 board incorporates the Mobile Intel
Chipset for Embedded Computing, consisting of the Intel
Graphic Memory Controller Hub (GMCH) and Intel
Hub 7-M (ICH7-M), an optimized integrated graphics solution with a
533MHz and 667MHz front-side bus. Dimensions of the board are
95mm x 125mm.
The integrated powerful 3D graphics engine, based on Intel® Graphics
Media Accelerator 950 (Intel
®
GMA 950) architecture, operates at core
speeds of up to 400 MHz. It features a low-power design and is validated
with the Intel® Core Duo/Solo on 65nm process. With DDR2 667MHz
SO-DIMM socket on board, the board supports up to 2GB of DDR2
system memory.
®
Graphics Media Accelerator 950 supports a unique intelligent
Intel
memory management scheme called Dynamic Video Memory
Technology (DVMT). DVMT handles diverse applications by providing
the maximum (224MB) availability of system memory for general
computer usage, while supplying additional graphics memory when a
3D-intensive application requests it. The Intel GMA 950 graphics
architecture also takes advantage of the high-performance Intel
processor. Intel GMA 950 graphics supports Dual Independent Display
technology.
The main features of the board are:
Supports COM ETX Type II Module pin-out definitions
Supports Intel

CoreTM Duo/Solo processors
Supports up to 533/667MHz FSB
One DDR2 SDRAM SO-DIMM, Max. 2GB

INTRODUCTION
Installing the Processor
The ET900 is available with a processor socket on board or with an
Intel® processor on board. In the case that your ET900 comes a Socket
479 processor socket for Intel
follow the instructions below regarding the processor installation.
The processor socket comes with a screw to secure the processor. As
shown in the left picture below, loosen the screw first before inserting
the processor. Place the processor into the socket by making sure the
notch on the corner of the processor corresponds with the notch on the
inside of the socket. Once the processor has slide into the socket, fasten
the screw. Refer to the figures below.
®
Pentium® M or Celeron® M processors,
NOTE:
Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.

INTRODUCTION
Installing the Memory
The ET900 COM Express CPU module accommodates 200-pin
DDR2-533 and DDR2-667 SODIMM memory modules with capacities
up to 2GB. Non-ECC is supported.
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 align
with those 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 m odule can be i nst al l ed
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.

Connectors on ET900
J2, J3: COM Express Type 2 Connectors
The Type 2 connectors come in two 220-pin 0.5mm pitch receptacles.
They include PCI, IDE, GBE and up to 22 general-purpose PCIE lanes
(PCIE 0-5 and PCIE 16-31). For most Type 2 implementations, it is
expected that PCIE lanes 16-31 are used for graphics. Hence they are
designated PEG lanes 0-15 in the following table. Modules
implementing Pin out Type 2, such as the ET900, uses the pin-out
shown.
