Power Supply Chapter: Detailed Description
3 Detailed Description
3.1 Power Supply
The power supply of the hardware module is effected via the power connector. The board only requires
an operating voltage of 5 volt ± 5%, it is not necessary to connect all indicated voltages. Additional
voltages may only be necessary for PC/104 expansion cards. For safety reasons it is recommended to
connect all power pins of the PC/104 connector to the power supply as well.
3.2 CPU
The board comes with an AMD® Geode® LX800 CPU running at a clock speed of 500MHz. The package
type allows operation under a maximum case temperature of 60 degrees Celsius (extended temperature
range on request) and accords highest possible security even in rough environment.
The processor includes a second level cache of 128 KByte. Furthermore, all Geode® LX processors offer
many features known from the desktop range such as MMX®, 3DNow!®, loadable microcode etc.
3.3 Memory
There is one conventional SO-DIMM200 socket available to equip the board with memory. For technical
and mechanical reasons it is possible that particular memory modules cannot be employed. Please ask
your sales representative for recommended memory modules.
With currently available SO-DIMM200 modules a memory extension up to 1 GByte is possible
(DDR-400).

USB 1 to 4, LAN, Sound Chapter: Connectors
4.9 USB 1 to 4, LAN, Sound
USB 1-4, LAN and sound are provided via a standard IDC socket connector with a spacing of 2.54 mm.
Necessary settings can be accomplished in BIOS setup.
All USB-channels support USB 2.0. You may note that the setting of USB keyboard or USB mouse
support in the BIOS-setup is only necessary and advisable, if the OS offers no USB-support. BIOS-setup
can be changed with a USB keyboard without enabling USB keyboard support. Running a USB
supporting OS (such as Microsoft® Windows®) with these features enabled may lead to significant
performance or functionality limitations.
Every USB interface provides up to 500 mA current and is protected by an electronically resettable fuse.
The LAN-interface on this connector supports 10BaseT and 100BaseT compatible network components
with automatic bandwidth selection. Additional outputs are provided for status LEDs. Auto-negotiate and
auto-cross functionality is available, PXE and RPL are available on request.
AC'97 - 2.3 compatible audio I/O is available on this connector. There are two ways to use these signals.
Default functionality is the familiar audio in, audio out, and microphone (2-channel mode). OS dependent
device drivers can switch these signals to support an 5.1 output; thus in this mode no audio input signals
are available. In 2-channel mode LOUT is the only active audio output. Moth MIC inputs are available. In
6-channel mode the speaker outputs are: LOUT to Front, AUXA to Surround, MIC1 to Center and MIC2 to
LFE (Sub).
The signals "SPDIFI" and "SPDIFO" provide digital input and output. If a transformation to a coaxial or
optical connector is necessary this must be performed externally.
CAUTION
The same IDC socket connector supports all three devices and is not "keyed"! Misconnected support
cables may short two devices together and damage the board. Please check diagrams before installing
any connecting cables to ensure proper connection.

Chapter: BIOS Settings Remarks for Setup Use
5 BIOS Settings
5.1 Remarks for Setup Use
In a setup page, standard values for its setup entries can be loaded. Fail-safe defaults are loaded with F6
and optimized defaults are loaded with F7. These standard values are independent of the fact that a
board has successfully booted with a setup setting before.
This is different if these defaults are called from the Top Menu. Once a setup setting was saved, which
subsequently leads to a successful boot process, those values are loaded as default for all setup items
afterwards.
See also the chapters “Load Fail-Safe Defaults" (5.10) and “Load Optimized Defaults” (5.11).
NOTE
BIOS features and setup options are subject to change without notice. The settings displayed in the
screenshots on the following pages are meant to be examples only. They do not represent the
recommended settings or the default settings. Determination of the appropriate settings is dependent
upon the particular application scenario in which the board is used.

Load Fail-Safe Defaults Chapter: BIOS Settings
5.10 Load Fail-Safe Defaults
If this option is chosen, the last working setup is loaded from flash. Working means that the setup setting
has already led to a successful boot process.
At the first setting of the BIOS setup, safe values are loaded which lets the board boot. This status is
reached again, if the board is reprogrammed with the corresponding flash-program and the required
parameters.
5.11 Load Optimized Defaults
This option applies like described under “Remarks for Setup Use” (5.1).
At first start of the BIOS, optimized values are loaded from the setup, which are supposed to make the
board boot. This status is achieved again, if the board is reprogrammed using the flash program with the
required parameters.
5.12 Set Password
Here you can enter a password to protect the BIOS settings against unauthorized changes. Use this
option with care! Forgotten or lost passwords are a frequent problem.
5.13 Save & Exit Setup
Settings are saved and the board is restarted.
5.14 Exit Without Saving
This option leaves the setup without saving any changes.
Beckhoff New Automation Technology CB4021 page 55
Chapter: BIOS update Exit Without Saving
6 BIOS update
If a BIOS update becomes necessary, the program “AWDFLASH.EXE” from Phoenix Technologies is
used for this. It is important, that the program is started from a DOS environment without a virtual memory
manager such as for example “EMM386.EXE”. In case such a memory manager is loaded, the program
will stop with an error message.
The system must not be interrupted during the flash process, otherwise the update is stopped and the
BIOS is destroyed afterwards.
The program should be started as follows:
awdflash [biosfilename] /sn /cc /cp
/sn Do not save the current BIOS
/cc Clear the CMOS
/cp Clear the PnP information
The erasure of CMOS and PnP is strongly recommended. This ensures, that the new BIOS works
correctly and that all chipset registers, which were saved in the setup, are reinitialized through the BIOS.
DMI should only be erased (option /cd) if the BIOS supplier advises to do so.
A complete description of all valid parameters is shown with the parameter “/?”.
In order to make the updating process run automatically, the parameter “/py” must be added. This
parameter bypasses all security checks during programming.
CAUTION
Updating the BIOS in an improper way can render the board unusable. Therefore, you should only update
the BIOS if you really need the changes/corrections which come with the new BIOS version.
CAUTION
Before you proceed to update the BIOS you need to make absolutely sure that you have the right BIOS
file which was issued for the exact board and exact board revision that you wish to update. If you try to
update the BIOS using the wrong file the board will not start up again.

Beckhoff New Automation Technology CB4021 page 59
Chapter: Technical Data Thermal Specifications
8.3 Thermal Specifications
The board is specified to operate in an environmental temperature range from 0°C to +60°C (extended
temperature on request). Maximum die temperature is 100°C. To keep the processor under this threshold
an appropriate cooling solution needs to be applied. This solution has to take typical and maximum power
consumption into account. The maximum power consumption may be twice as high and should be used
as a basis for the cooling concept. Additional controllers may also affect the cooling concept. The power
consumption of such components may be comparable to the consumption of the processor.
The board design includes thermal solution mounting points that will provide the best possible thermal
interface between die and solution. Since we take thermal solutions seriously we have several advanced,
aggressive cooling solutions in our product portfolio. Please contact your sales representative to order or
discuss your thermal solution needs.
CAUTION
The end customer has the responsibility to ensure that the die temperature of the processor does not
exceed 100°C. Permanent overheating may destroy the board!
In case the temperature exceeds 100°C the environmental temperature must be reduced. Under certain
circumstances sufficient air circulation must be provided.
