Environmental Protection Statement
This product has been manufactured to satisfy environmental protection requirements wherever possible. Many of the
components used (structural parts, printed circuit boards, connectors, batteries, etc.) are capable of being recycled.
Final disposal of this product after its service life must be accomplished in accordance with applicable country, state,
or local laws or regulations. All components within this product fulfill the requirements of the RoHS (Restriction of
Hazardous Substances Directive). The product is soldered with a lead free process.
1.8
RoHS Commitment
Kontron Compact Computers AG (Switzerland) is committed to develop and produce environmentally friendly products
according to the Restriction of Hazardous Substances (RoHS) Directive (2002/95/EC) and the Waste Electrical and
Electronic Equipment (WEEE) Directive (2002/96/EC) established by the European Union. The RoHS directive was
adopted in February 2003 by the European Union and came into effect on July 1, 2006. It is not a law but a directive,
which restricts the use of six hazardous materials in the manufacturing of various types of electronic and electrical
equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC,
which has set targets for collection, recycling and recovery of electrical goods and is part of a legislative initiative to
solve the problem of huge amounts of toxic e-waste.
Each European Union member state is adopting its own enforcement and implementation policies using the directive
as a guide. Therefore, there could be as many different versions of the law as there are states in the EU. Additionally,
non-EU countries like China, Japan, or states in the U.S. such as California may have their own regulations for green
products, which are similar, but not identical, to the RoHS directive.
RoHS is often referred to as the "lead-free" directive but it restricts the use of the following substances:
» Lead
» Mercury
» Cadmium
» Chromium VI
» PBB and PBDE
The maximum allowable concentration of any of the above mentioned substances is 0.1% (except for Cadmium, which
is limited to 0.01%) by weight of homogeneous material. This means that the limits do not apply to the weight of the
finished product, or even to a component but to any single substance that could (theoretically) be separated
mechanically.

1.8.1 RoHS Compatible Product Design
All standard products from Kontron Compact Computers (KCC) comply with RoHS legislation.
Since July 1, 2006, there has been a strict adherence to the use of RoHS compliant electronic and mechanical
components during the design-in phase of all KCC standard products.
1.8.2 RoHS Compliant Production Process
KCC selects external suppliers that are capable of producing RoHS compliant devices verified by:
» A confirmation from the supplier indicating that their production processes and resulting devices are RoHS
compliant.
» If there is any doubt of the RoHS compliancy, the concentration of the previously mentioned substances in a
produced device will be measured. These measurements are carried out by an accredited laboratory.
1.8.3 WEEE Application
The WEEE directive is closely related to the RoHS directive and applies to the following devices:
» Large and small household appliances
» IT equipment
» Telecommunications equipment (although infrastructure equipment is exempt in some countries)
» Consumer equipment
» Lighting equipment – including light bulbs
» Electronic and electrical tools
» Toys, leisure and sports equipment
» Automatic dispensers
It does not apply to fixed industrial plants and tools. The compliance is the responsibility of the company that brings
the product to market, as defined in the directive. Components and sub-assemblies are not subject to product
compliance. In other words, since Kontron Compact Computers AG does not deliver ready-made products to end users
the WEEE directive is not applicable for KCC. Users are nevertheless encouraged to properly recycle all electronic
products that have reached the end of their life cycle.
1.9

3.4.2 ELinOS
KCC works in cooperation with SYSGO and therefore recommends using the ELinOS Linux distribution.
http://www.elinos.com/
SYSGO has developed a board support package (BSP) for the Pentium M and the Pentium BX/TX chipset-based
products for ELinOS. If you are interested or if you have any questions about ELinOS, please contact SYSGO directly.
3.4.3 What is ELinOS?
ELinOS is a development environment based on Linux for the creation of embedded systems for intelligent devices.
With ELinOS the memory demand of Linux is reduced to less than 1MB ROM and 2MB RAM. In this manner Linux can,
for the first time, conform to the reduced hardware conditions of embedded systems. Even in this basic configuration,
Linux offers largely the same functionality which made it so popular in the server and desktop field. By virtue of access
to the constantly growing number of Linux components, the basic system can be expanded at any time.
The core of ELinOS is a Linux distribution custom-tailored to the embedded systems currently sold. Besides the wellknown Linux version for x86, ELinOS also supports PowerPC-, ARM-, MIPS-, and SH3-platforms which are very popular
in the embedded field.
The emphasis of the current version of ELinOS is on the new CoTools, CODEO and COGNITO. CODEO is Eclipse based and
provides additional plug-ins for project management and target communication, which substantially improves the
ease of development of applications with ELinOS. COGNITO is a further integrated tool for the analysis of system
performance. It permits the collection, recording and display of all system information and facilitates the fast
optimization of software for intelligent devices.
ELinOS has been updated to the new version of the GNU tool chain and contains the stable Linux Kernel starting with
version 2.4.25; it has integration of Java and the real-time extensions RTAI 3.0 for hard real-time requirements. The
package is complemented with Carrier Grade Extensions such as IPv6, IPSec, SNMP, etc., for the use of Linux in
applications in the telecommunications market.

4.1.6 Windows XP 2nd IDE Bug Fix
Most PC-AT chipsets contain a dual IDE controller. The AMD Geode™ CS5536 and CS5535 companion devices contain
only a single IDE controller. These companion devices use the same out-of-box Windows® XP IDE driver as other
compatible chipsets.
This may present a problem since the driver will assume a dual controller is present. The result is that, system
resources may become reserved and unavailable for other devices. Install the following .reg file from the
Product CD:
DRIVERS\WinXP-Win2K\IDE\General-IDE-Driver\XP Geode disable IDE2.reg
This reg file (XP Geode disable IDE2.reg) disables the second IDE controller in the XP OS.
The changes do not affect the performance of the IDE controller but simply allow the resources to be used elsewhere.
4.1.7 VideoIn
The VideoInput function (frame grabber) is available in conjunction with the MSB800, MPC21, MSEP800 and optional
on the MPCV800. The low cost version MSB800L and MSEP800L do not include this feature.
The Geode LX800 / LX900 contains a low cost video input port. It consist of LX800 / LX900's video input port (VIP) and
the external frame grabber chip SAA7111A from Philips. This port is capable of digitizing a CVBS video signal with 15
frames per second at a resolution of 352 x 288bits. Note that this frame rate is only achievable when the raw data
stream is compressed before being stored on the hard drive. Driver support is currently available for the Windows XP
platform.
With higher resolutions, the frame rate will decrease.

Remote Control over COM Port
5.2.1 Requirements
» Serial null-modem cable (only RX and TX)
» Remote computer: Serial port address 3F8h
» Host computer:
Serial port COM1 or COM2, OS (Windows or MSDOS), floppy image file with MSDOS 6.22
or FREEDOS (eg. freedos2img which is located on the Product CD or in the download area).
5.2.2 Limitations
» OS on the remote computer:
» Enabling "remote floppy" support:
MSDOS or FREEDOS
All other floppy disks on the remote computer will be disabled
5.2.3 Principles of Functionality
The main principles are based on the hooks of vectors INT10(video), INT13(disk) and INT16(keyboard) in a special
(DLINT) ROM extension, which redirects the command interrupt requests over the serial COM port to the remote
console running on another (host) computer under Windows or MSDOS.
During startup, DLINT ROM module tries to initiate communication over the COM port. If this initial communication is
unsuccessful, the remote access feature will be disabled. If the initial connection is successful, DLINT module asks for
supported options and initializes appropriated TSR vectors. Options which are not enabled in remote console will stay
native on the remote computer. Remote connection was successfully established if, in the upper left corner, the
message "Press F1 for Setup" appears.
5.2.4 BIOS Settings on the Remote Computer
To enable a remote COM port for remote control:
4.
5.
6.
7.
8.
During boot up, press F1 to enter the BIOS setup
Enter "C. Motherboard Device Configuration"
Enter "I/O Configuration"
Select "Remote control over COM port"
Set "Remote:" to Enabled
For proper functionality, the serial port address must be set under "LPC Card devices":
"Serial Port 1: 0x3f8" to 3F8 hex address. If the remote floppy disk feature will be used, then "Floppy BIOS Support"
must be enabled in the BIOS setup.
Note:
23
All remote features are supported only under FREEDOS or MSDOS 6.22.
When the remote floppy option is enabled, it is impossible to use another floppy disk; even the USB floppy is
not accessible.

Geode LX800 / LX900 / Software
5.2.5 Settings on the Host Computer
Note:
The remote console application must be loaded and connected before switching on (BIOS start) the remote
computer.
Windows Tool
Supported options such as "Keyboard", "Video" and "Floppy…" must be chosen before connection. The remote
application simulates floppy disk access over the "floppy image file".
Connect to the FreeDos Image file by enabling the option "Floppy…":
After that press "Connect".
Windows application RemoteLX800.exe
Please start the remote computer now.
24
www.kontron.com
Geode LX800 / LX900 / Software
Functions:
R – enabling this option is helpful when the remote application is working in direct video mode without using the
BIOS Int10 functions. Every 0.5-1 seconds, the windows application will send a request to the remote computer to
refresh a screen on the host computer. For example, if you want to use the "Volkov Commander VC", you must enable
this feature.
Ctrl-Alt-Del Simulation: The Windows OS hooks the Ctrl-Alt-Del keys sequence and sends a signal from the host
console to the remote computer. Press Ctrl-Alt and the on-screen Del button by mouse click.
DOS Tool
Note:
All remote features are supported only under FREEDOS or MSDOS 6.22.
When the remote floppy option is enabled, it is impossible to use another floppy disk; even the USB floppy is
not accessible.
MSDOS application remlx800.exe
Options for MSDOS applications can be changed in the REMLX800.INI file.
» PORT=1:
use COM1 for remote control on the host computer
» KEYBOARD:
enable remote keyboard
» VIDEO:
enable remote video
» FLOPPY=FREEDOS2.IMG:
enable remote floppy and use FREEDOS2.IMG image file for floppy disk emulation
» MSDOS application does not support the direct video option

Video: INT 10 command interrupt
Remote video console supports only mode 3: text mode 80*25. In this mode it works like a twin of the main
display, which is always enabled.
AH = 0, AL=3: only, all other modes will be ignored on the remote console
AH = 2:
set cursor position (display page = 0)
AH = 6:
scroll up
AH = 7:
scroll down
AH =9:
write "char" and attribute
AH = 0Ah: write "char" and attribute
AH = 0Eh: write "char" teletype
AH = 13h: write text string (emulated over AH = 2 and AH = 0Eh commands)
Note:
Remote "emulator" does not support direct access to the screen memory. Popular software, such as Norton
Commander, will not work properly with remote video console, and the picture will be visible only on the
remote computer screen.
Floppy Disk: INT 13
When the remote floppy disk is enabled, all floppy disk requests will be redirected to the remote console
application; all requests to the hard disk will be executed by the native BIOS.
To make the "remote floppy disk" bootable, it is necessary to make a floppy image from a bootable floppy disk.

Access to these resources under DOS can be provided by the INT 15h function, see Section 5.1.
Access under Windows 98, ME, 2000 and XP can be provided by the "Int15dl"-WDM driver; under Windows-NT with the
"Int15dl"-NT driver.
At the moment this driver supports all Kontron Compact Computer boards with PIIX4 and ICH4 chipsets (eg. MSM855,
MSEBX855, MSMP5SEV, MSMP3SEV, MSEP800, etc.). The driver can be found on the Product CD or in the download
area of the support center.

» WinInt15.exe (Int15 function test tool)
» T855.exe (Temperatur sensor (SMBUS) monitor)
Driver Installation W2k/XP
"Int15dl" is not a plug-and-play driver, it must be installed manually:
1.
Open the "Control Panel".
2.
Double-click on "Add/Remove Hardware".
3.
To continue click the “Next>” button.
4.
On the page "Choose a Hardware Task", check "Add/Troubleshoot a device" and click "Next>".
5.
After "New hardware detection", a windows automatic procedure, choose "Add a new device" and click the
"Next>" button.
6.
In the "Find New Hardware" page, choose "No, I want to select the hardware from a list" and click "Next>".
7.
Choose "Other devices" in the "Hardware Type" list and click the "Next>" button.
8.
On the page "Select a Device Driver" press "Have Disk..." button and find the driver location (Int15dl.inf WDM). After opening the "inf" file, the installation program will show a Models list and "DIGITAL-LOGIC
INT15 functions emulator" string. Press the "Next>" button.
9.
Then press "Finish" button; it is not necessary to restart the computer after installation.
10. After installation, please be sure that "DIGITAL-LOGIC INT15 functions emulator" has been installed
properly. Open "Control Panel", then double-click on "System" icon. Choose the "Hardware" tab and click
on the "Device Manager" button. Expand "System Devices" and double-click on "DIGITAL-LOGIC INT15
functions emulator". Be sure, that device is working properly.
Programming the Int15dl Interface under Windows
Programming of the Int15dl Interface is very similar to DOS programming, based on the DeviceIOControl function,
which operates with a pre-defined structure named "Registers".
Files:
Int15srv.h: contains definitions for the Registers structure.
Int15dlioctl.h: contains definitions for the IO control code constants.
Test_Int15dl.cpp: Sample subroutines providing access to hardware functions over the Int15dl driver.
Functions (Test_Int15dl.cpp)
bool Int15 (Registers *Regs): the main function, which sends user requests to the driver.
Returns true if the request finished successfully; otherwise it returns false.
Regs: address of the Registers structure containing specific request data (defined in Int15srv.h).
31
www.kontron.com
Geode LX800 / LX900 / Special Peripherals, Configurations, Software
For example, the following code will initiate temperature measuring:
Registers Regs;
Regs.ah = 0xEC;
if(!Int15(&Regs)) //error in driver request
{
printf("Error reading temperature\n");
return;
}
//success - temperature value is in Regs.al
if(Regs.bl == 0)printf("\tTemperature = %d C\n",Regs.al);
//error - not valid value
else printf("\tError reading Temperature\n");
Note:
Input and output arguments of the Int15 function vary for different chipsets and BIOSes. Read the User
Manual on defining registers.
For example:
To get a temperature value on a board with a PIIX4 chipset, use "Regs.ah = 0xEC;" but on a board
with an ICH4 chipset, use "Regs.ax = 0x78EC;".
bool Open_Int15dl(void): the first function and must be called to create a link between the "DIGITAL-LOGIC INT15
functions emulator" driver and the user software. It returns true if the device was successfully opened; otherwise it
returns false.
void Close_Int15dl(void): the last function, it breaks the link between the driver and the user software.
int GetChipID(void): an additional service function; it returns the type of chipset (for PIIX4 = 4, for ICH4 = 5).
Registers Structure
This is used for exchanging information between the user program and the "Int15dl" driver.
typedef struct Registers {
union {
struct {
unsigned short ax;
unsigned short bx;
unsigned short cx;
unsigned short dx;
unsigned short bp;
unsigned short si;
unsigned short di;
unsigned short ds;
unsigned short es;
unsigned short flags;
};
struct {
unsigned char al;
unsigned char ah;
unsigned char bl;
unsigned char bh;
unsigned char cl;
unsigned char ch;
unsigned char dl;
unsigned char dh;
};
};
} TRegisters;

Information for Advanced Users
At the first call of the function Open_Int15dl(), the Int15dl driver tries to detect the type of chipset. To disable this
procedure the user must define the following parameters in the "Int15dl.inf" file before installing the driver:
For PIIX4 chipset:
HKR, "Parameters", "chipID", 0x00010001, 0x4
HKR, "Parameters", "pmBase", 0x00010001, 0x1000
HKR, "Parameters", "smbBase", 0x00010001, 0x1040
HKR, "Parameters", "tsaddr", 0x00010001, 0x9E - LM75 sensor address
For ICH4 chipset:
HKR, "Parameters", "chipID", 0x00010001, 0x5
HKR, "Parameters", "pmBase", 0x00010001, 0x1000
HKR, "Parameters", "smbBase", 0x00010001, 0x1880
HKR, "Parameters", "tsaddr", 0x00010001, 0x9C - ADM1023 sensor address

Core BIOS Download
Before downloading a BIOS, please check the following:
Make a bootable diskette which includes the following files:
» Flashrom.com
» core BIOS xxxxxxxx.yyy
IMPORTANT:
Note:
»
»
»
»
»
Do not use boot disks created in a Windows operating system. If you do not have an MSDOS 6.22 disk
available, you can download a boot disk from www.bootdisk.com .
Disable the EMM386 or other memory managers in the CONFIG.SYS of your bootdisk.
Make sure that the FlashROM.com program and the BIOS to be downloaded are in the same path and
directory!
Boot DOS without config.sys and autoexec.batpress F5 while starting the DOS boot.
Is the empty disk space, where the FlashROM.com is located, larger than 64kB (for safe storage)?
Is the floppy disk not write-protected?
Start the DOWNLOADING process:
1.
Start the system with the bootable diskette. If you do not have a bootable diskette or floppy drive you can
start in DOS mode by pressing the F5 key to disable autoexec.bat and config.sys.
2.
Run FlashROM.com as follows: FLASHROM /sFFFC0000 biosname.xxx
3.
Power off the system.
4.
After powering the system back up, press F1 to enter the setup mode and set the default values ("L").
5.
"Save and leave" the setup ("X").
6.
Switch off the system after the download is completed.
If the download does not work:
» Check to be sure no EMM386 is loaded.
» Check if there is a peripheral card in the system, which occupies the same memory range. If present,
disconnect this card.
» If the download has stopped or is not completed, make a warm boot and repeat the steps or download
another file. As the video may be shadowed, everything is visible and a cold boot would clear the screen so
nothing would be visible afterwards.
Attention!
35
Since FlashROM version 12.05, it is also possible to update the
BIOS from a USB device (USB bootstick).
If you have two IDE devices attached to the board (e.g. HDD and CD-ROM),
disconnect the CD-ROM before downloading the BIOS.

7.3.4 System Clock/PLL and Clock Gating Configuration
The system clock/PLL allows the setting of the clocks for the AMD Geode™ system.
Clock Mode: Allows the clock speed to be determined by either the hardware strapping or the manual settings. If the
H/W strapping option is selected, then the manual divisor settings will be grayed out.
Manual divisor settings:
Mdiv: Options from 2 to 17.
Vdiv: Options from 2 to 9.
FbDiv: Options from 6 to 61.
The formula for the MDiv, VDiv, and FbDiv is as follows:
(PCI*FbDiv)/VDiv = CPU speed and (PCI*FbDiv)/MDiv = GeodeLink™ speed.
7.3.5 Power Management
This menu is for configuring the BIOS's power management in relation to the installed OS. The LX800 / LX900
supports ACPI and APM Version 1.2.
The following ACPI Sleep States are supported:

7.3.7 ISA I/O
ISA Bus I/O Recovery Time
The recovery time of back to back ISA I/O cycles is 1.5 BCLK (ISA System BUS clock). The IT8888 provides different I/O
recovery time settings for 8bit I/O cycles and 16bit I/O cycles. The configured 8bit I/O recovery time is inserted after
ISA I/F finishes the 8bit I/O cycle, and the configured 16bit I/O recovery time is inserted after ISA I/F finishes the
16bit I/O cycle. No additional recovery time will be inserted due to byte conversion (PCI I/O cycle could be
8/16/24/32 bits, but ISA I/O is only 8/16 bits).
This register is used by the system BIOS to set the ISA I/O recovery time between two different PCI I/O accesses (i.e.
no additional recovery wait state will be inserted during byte conversion).
16bit I/O Access Recovery Time
00b:3.5 BCLK, 01b:4.5 BCLK, 10b:5.5 BCLK, 11b: 7.5 BCLK
8bit I/O Access Recovery Time
00b:3.5 BCLK, 01b:5.5 BCLK, 10b:7.5 BCLK, 11b:11.5 BCLK
