Product Warranty
Evalue warrants to you, the original purchaser, that each of its products will be free from
defects in materials and workmanship for two years 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 authorized by Evalue, or which have been subject to
misuse, abuse, accident or improper installation. Evalue assumes no liability under the
terms of this warranty as a consequence of such events. Because of Evalue’s high
quality-control standards and rigorous testing, most of our customers never need to use our
repair service. If any of Evalue’s products 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, CPU type and
speed, Evalue’s products model name, hardware & BIOS revision number, other
hardware and software used, etc.) Note anything abnormal 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 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 good return more quickly.
4. Carefully pack the defective product, a complete Repair and Replacement Order Card
and a photocopy proof of purchase 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

1. Getting started
1.1 Safety Precautions
Warning!
Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should
open the PC chassis.
Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution,
use a grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded
bag when they are not in the chassis.

1.4 Manual Objectives
This manual describes in detail the Evalue Technology EMB-9670/9673 series Single
Board.
We have tried to include as much information as possible but we have not duplicated
information that is provided in the standard IBM Technical References, unless it proved to
be necessary to aid in the understanding of this board.
We strongly recommend that you study this manual carefully before attempting to interface
with EMB-9670/9673 series or change the standard configurations. Whilst all the necessary
information is available in this manual we would recommend that unless you are confident,
you contact your supplier for guidance.
Please be aware that it is possible to create configurations within the CMOS RAM that
make booting impossible. If this should happen, clear the CMOS settings, (see the
description of the Jumper Settings for details).
If you have any suggestions or find any errors concerning this manual and want to inform
us of these, please contact our Customer Service department with the relevant details.

The GMCH IGD provides a highly integrated graphics accelerator delivering high
performance 2D, 3D, and video capabilities. With its interfaces to UMA using a DVMT
configuration, an analog display, a LVDS port, and two digital display ports (e.g. flat panel),
the GMCH can provide a complete graphics solution.
The GMCH also provides 2D hardware acceleration for block transfers of data (BLTs). The
BLT engine provides the ability to copy a source block of data to a destination and perform
raster operations (e.g., ROP1, ROP2, and ROP3) on the data using a pattern, and/or
another destination. Performing these common tasks in hardware reduces CPU load, and
thus improves performance. High bandwidth access to data is provided through the system
memory interface. The GMCH uses Tiling architecture to increase system memory
efficiency and thus maximize effective rendering bandwidth. The Intel 855GM/855GME
GMCH improves 3D performance and quality with 3D Zone rendering technology. The Intel
855GME GMCH also supports Video Mixer rendering and Bi-Cubic filtering.

The Intel 855GM/855GME GMCH has four display ports, one analog and three digital. With
these interfaces, the GMCH can provide support for a progressive scan analog monitor, a
dedicated dual channel LVDS LCD panel, and two DVO devices. Each port can transmit
data according to one or more protocols. The data that is sent out the display port is
selected from one of the two possible sources, Pipe A or Pipe B.
The Intel 855GM/855GME GMCH have an integrated dual channel LFP Transmitter
interface to support LVDS LCD panel resolutions up to UXGA The display pipe provides
panel up-scaling to fit a smaller source image onto a specific native panel size, as well as
provides panning and centering support. The LVDS port is only supported on Pipe B. The
LVDS port can only be driven by Pipe B, either independently or simultaneously with the
Analog Display port. Spread Spectrum Clocking is supported: center and down spread
support of 0.5%, 1%, and 2.5% utilizing an external SSC clock.
The DVO B/C interface is compliant with the DVI Specification 1.0. When combined with a
DVI compliant external device (e.g. TMDS Flat Panel Transmitter, TV-out encoder, etc.),
the GMCH provides a high-speed interface to a digital or analog display (e.g. flat panel, TV
monitor, etc.). The DVO ports are connected to an external display device. Examples of this
are TV-out encoders, external DACs, LVDS transmitters, and TMDS transmitters. Each
display port has control signals that may be used to control, configure and/or determine the
capabilities of an external device. The GMCH provides two DVO ports that are each
capable of driving a 165-MHz pixel clock at the DVO B or DVO C interface. When DVO B
and DVO C are combined into a single DVO port, then an effective pixel rate of 330 MHz
can be achieved. The DVO B/C ports can be driven by Pipe A or Pipe
B. If driven on Pipe B, then the LVDS port must be disabled.
