2. Getting Started
Before You Begin
Before handling your ETXexpress-PM, read the instructions and safety guidelines on
the following pages to prevent damage to the product and to ensure your own personal
safety.
Always use caution when handling or operating a computer. Only qualified,
experienced, authorized electronics service personnel should access the interior
of a computer. The power supplies produce high voltages and energy hazards,
which can cause bodily harm.
If you have any problems or questions about the unit, please contact Kontron
Post-Sales Technical Support.
WARNING
High voltages are present inside a computer chassis when the
unit’s power cord is plugged into an electrical outlet. Turn off
system power, turn off the power supply, and then disconnect
the power cord from its source before removing the chassis
cover. Turning off the system power switch does not remove
power to components.
Unpacking
When unpacking, follow these steps:
1) After opening the box, save it and the packing material for possible future
shipment.
2) Remove all items from the box. If any items listed on the purchase order are
missing, notify Kontron customer service immediately.
3) Inspect the product for damage. If there is damage, notify Kontron customer
service immediately. Refer to “Guarantee and Warranty Policy” for the return
procedure.
ETXexpress-PM User’s Guide page 13
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources or
subsystems to prevent electric shock or system board damage. This does not
apply when hot swapping parts.
3) Follow the guidelines provided in “Preventing Electrostatic Discharge” in the
following section.
4) Disconnect any telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to system boards, wait five seconds after turning
off the computer before removing a component, removing a system board, or
disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs. If you are
disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before connecting a cable, make sure
both connectors are correctly oriented and aligned
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation and
follow proper ESD procedure to reduce the risk of damage to components. Kontron
strongly encourages you to follow proper ESD procedure, which can include wrist straps
and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component’s antistatic packing material until you are ready to install
the component in a computer. Just before unwrapping the antistatic packaging,
be sure you are at an ESD workstation or grounded. This will discharge any
static electricity that may have built up in your body.
When transporting a sensitive component, first place it in an antistatic container
or packaging.
Handle all sensitive components at an ESD workstation. If possible, use antistatic
floor pads and workbench pads.
page 14 ETXexpress-PM User’s Guide
Handle components and boards with care. Don’t touch the components or
contacts on a board. Hold a board by its edges or by its metal mounting bracket.
Do not handle or store system boards near strong electrostatic, electromagnetic,
magnetic, or radioactive fields.

DIMM RAM. For applications that require advanced real-time video capabilities, the
ETXexpress-PM has integrated graphics based on the Intel® Graphics Media
Accelerator 900 architecture. The ETXexpress-PM PCI Express provides two 4GB/sec
channels, one going upstream and the other downstream, for a total of 8GB/sec of
aggregate bandwidth.
The ETXexpress-PM supports PCI Express Cards with 4 PCI Express x1 Lanes as well
as established hardware solutions that are based on current buses such as the 32-bit
PCI. Either a 10/100 or 10/100/1000 megabit per second Ethernet port provides fast
connectivity to LAN/WAN. Modules with part numbers beginning with 38001 support
10/100 Ethernet. Modules with part numbers beginning with 38002 support Gigabit
Ethernet. Up to eight USB 2.0 ports provide fast interfaces for all your external
peripherals.
ETXexpress-PM User’s Guide page 17
Six mounting holes on the board provide secure mounting to better tolerate shock and
vibration.
ETXexpress-PM Module Overview
The international COM Express™ Specification defines two new form factor sizes:
Basic (95mm x 125mm) Module
Extended (110mm x 155mm) Module
The primary difference between the Basic and Extended Modules is that Extended
Modules have a larger board size and a thermal envelope.
Five Module Pin-out Types (1-5) exist for Basic and Extended modules, each offering
different functionalities. For a complete explanation of the features, pin-outs and signals
of each of the Module Pin-out Types 1-5, please see the COM Express™ Specification.
The COM Express™ Specification is available on the PICMG (PCI Industrial Computer
Manufacturers Group) Web site: www.picmg.org. There is a fee for the document. All
Kontron ETXexpress Modules are based upon the COM Express™ Specification, which
Kontron played the lead role in developing.
The ETXexpress-PM uses the Pin-out Type 2 architecture, which includes PCI and IDE
interfaces. These modules either use onboard graphics capabilities or may use 16 PCI
Express Graphics (PEG) lanes to connect to an external video controller. For graphics,
PEG pins may be alternatively used for two SDVO ports.
Module Pin-out Type 2 features include:
Dual 220 pin connectors (Rows A-B and Rows C-D, 440 pins total)
32-bit PCI interface
IDE port (to support legacy ATA devices such as CD-ROM drives and Compact
Flash storage cards)
Up to 22 PCI Express lanes (up to 6 on Rows A-B and up to 16 on Rows C-D)

About PCI Express
PCI Express has become the primary data path for upcoming x86 based systems. Non
PCI Express components such as PCI plug-in cards can still be supported with the PCI
2.1 32-bit interface. ETXexpress COMs will continue supporting the PCI bus for legacy
applications.
PCI Express is an international I/O interconnect bus standard that expands on and
doubles the data transfer rates of the original PCI bus standard. PCI Express is a two-
way, serial connection that carries data in packets along two pairs of point-to-point data
lanes, compared to the single parallel data bus of traditional PCI that routes data at a
set rate.
Initial bit rates for PCI Express reach 2.5Gb/s per lane direction, which equate to data
transfer rates of approximately 200MB/s. A group of companies, headed by Kontron,
developed the COM Express™ Specification so that high-speed interconnects such as
1394b (Firewire), USB 2.0, InfiniBand and Gigabit Ethernet would have an I/O
architecture suitable for their high transfer speeds.
Thermal Management
Heat-spreader Plate
The heat-spreader is a 2mm-thick aluminum plate. It provides a thermal-interface
surface for heat removal from the ETXexpress module.
The heat-spreader is thermally coupled to the CPU die or package surface, and it also
may be coupled to other heat-generating devices on the module (chipset, VGA chip).
The heat spreader is not intended as a heat sink, although it may be suitable for this
purpose on low-power modules that operate under benign conditions.
Higher-power modules or higher-temperature conditions probably require heat-removal
devices such as a heat sink and fan, heat pipe, a larger heat sink attached to the heat-
spreader, or it may need to be thermally-coupled to a chassis.

LPC
The Low Pin Count (LPC) Interface Specification for legacy I/O has facilitated the
industry's transition toward ISA-less systems. The LPC interface allows legacy I/O
motherboard components, typically integrated in a Super I/O chip, to migrate from the
ISA/X-bus to the LPC interface while retaining full software compatibility.
The LPC interface offers several key advantages over ISA/X-bus, such as reduced pin
count for easier, more cost-effective design. The LPC interface is software-transparent
for I/O functions and compatible with existing peripheral devices and applications such
as parallel and serial ports, keyboards, and mice.
The LPC Interface Specification describes memory, I/O, and DMA transactions. Unlike
ISA, which runs at 8MHz, LPC uses the PCI 33MHz clock and is compatible with more
advanced silicon processes. The reduced pin count uses less space and power and is
more thermal-efficient.
Configuration
The BIOS automatically configures the settings.
page 36 ETXexpress-PM User’s Guide
Serial ATA

PCI Express
The ETXexpress-PM supports PCI Express Cards via 4 PCI Express lanes as well as
established hardware solutions based on current buses such as the 32-bit PCI bus.
PCI Express is an I/O interconnect bus standard (which includes a protocol and a
layered architecture) that expands on and doubles the data transfer rates of the original
PCI specification. PCI Express is a two-way, serial connection that carries data in
packets along two pairs of point-to-point data lanes, compared to the single parallel data
bus of traditional PCI that routes data at a set rate.
Initial bit rates for PCI Express reach 2.5Gb per second per lane direction, which equate
to data transfer rates of approximately 200MB per second. PCI Express was developed
so that high-speed interconnects such as Firewire (1394b), USB 2.0, InfiniBand, and
Gigabit Ethernet would have an I/O architecture suitable for high-speed transfers.
Configuration

Introduction
The ETXexpress-PM uses an AMIBIOS, which is located in the Flash memory. The
BIOS version displays onscreen during the POST at boot. The device has an 8-bit
access. The shadow RAM feature offers faster access (16 bit). You can update the
BIOS using a Flash utility. For complete AMIBIOS information, visit the AMIBIOS Web
site.
Determining the BIOS Version
To determine the AMIBIOS version, immediately press the Delete key on your keyboard
as soon as you see the following text display in the upper left corner of your screen:
AMBIOS © 2003 American Megatrends
BIOS Date: 03/14/05 17:36:08 Ver. ETX1R003
ETXexpress-PM User’s Guide page 49
Configuring the System BIOS
The AMIBIOS setup utility allows you to change system behavior by modifying the BIOS
configuration. Setup-utility menus allow you to make changes and turn features on or off.
AMIBIOS setup menus represent those found in most models of the ETXexpress-PM.
The BIOS setup utility for specific models can differ slightly.
Note: Selecting incorrect values can cause system boot failure. Load setup-
default values to recover by pressing to enter Setup
The Main Menu then appears.

What they say about us
FANTASTIC RESOURCE
One of our top priorities is maintaining our business with precision, and we are constantly looking for affiliates that can help us achieve our goal. With the aid of GID Industrial, our obsolete product management has never been more efficient. They have been a great resource to our company, and have quickly become a go-to supplier on our list!
Bucher Emhart Glass
EXCELLENT SERVICE
With our strict fundamentals and high expectations, we were surprised when we came across GID Industrial and their competitive pricing. When we approached them with our issue, they were incredibly confident in being able to provide us with a seamless solution at the best price for us. GID Industrial quickly understood our needs and provided us with excellent service, as well as fully tested product to ensure what we received would be the right fit for our company.
Fuji
HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
