KTD-S0006-B 2 Page 3 BIOS Update BIOS Update The KONTRON update tool (based on the AMD utility 'FlashROM.com') is only available for the DOS operating system. First copy the files LX800UPD.EXE, UPDATE.EXT (absolutely essential) and the BIOS file to a directory. Only the following combination of command line arguments has been tested and should be used for the update process. Note: COMMAND.COM must reside in the same directory or alternatively there has to be a valid path in the variable COMSPEC.

KTD-S0006-B 3.1.2 Page 6 Graphics Interface ace 24 Bit Color Mapping Tips The double pixel clock or 24-bit color depth can generally be taken from the datasheet. There are two interface modes existing at 24-bit color depth: FPDI (F (Flat Panel Display Interface) or LDI (LVDS Display Interface). Some panels use the line SELL LVDS (SELect Lvds data order). The LVDS data assignment in the datasheet can give you an indication by the last channel (e.g.
KTD-S0006-B 3.2 Page 7 Graphics Interface EDID 1.3 Specification (VESA) The EDID (Extended Display Identification Data) record has a fixed structure. The first 8 bytes contain the distinctive identification 00h, FFh, FFh, FFh, FFh, FFh, FFh, 00h. The end of the record is marked by the checksum (1 byte). The result of the addition of all bytes including the checksum has to be zero. For a comprehensive support of the majority of available panels you don't need all fields of the EDID record.
KTD-S0006-B 3.3.2 Page 8 Graphics Interface DisplayIDTM Restrictions Depending on the graphic controller not all features can be used. The following table shows the most important restrictions. Restrictions for MOPSlcdLX Panels with dual or quad clock not supported (2 or 4 Pixel per Clock) Variable power sequencing not supported DisplayIDTM is not a solution for every LCD. Many displays center the picture automatically using the DEsignal.
KTD-S0006-B 3.3.4 Page 9 Graphics Interface DisplayIDTM Windows® Tool The DisplayIDTM parameter can be modified with the DisplayIDTM Windows® tool. For an example the following picture shows the input fields for the Detailed Timing parameters. For more information see the documentation of the DisplayIDTM tool (software can be downloaded from kontron.com).
KTD-S0006-B Page 10 Graphics Interface The DisplayIDTM Editor saves the parameters in a intermediate file format. The file extension is 'KDD' (Kontron DisplayIDTM Data). This file format cannot be used to program the onboard EEPROM. For transfering this file format into the binary file format for the EEPROM apply the Converter. Building DisplayIDTM File 3.3.5 Start the Windows® tool DisplayID.exe.

KTD-S0006-B 5 Page 13 Remote Control (JRC) Remote Control (JRC) The Remote Control option provides a way to intercept and reroute certain BIOS functionality over a serial port at an early stage during the boot process. There are two distinct software components involved: the first component is part of the BIOS (client), the second component runs on a different device (host) that is connected using a serial cable to the client. This component is available as a WIN32 (JRC.EXE respectively jrc1i1xx.
KTD-S0006-B 6 Page 14 JIDA32 Interface JIDA32 Interface Most KONTRON single board computers (SBCs) are equipped with unique hardware features that cannot be accessed with standard API. The JIDA32 interface allows you to access this features in a hardware independent manner under popular 32-bit operating systems. Not mentioned parts of the JIDA32 interface are not supported and can lead to wrong results. 6.

A damage of these parameters leads to a loss of warranty. Due to this a write cycle may only be performed above a defined address. 6.3.

Instead precompiled objects are provided that can be used to build a JIDA32 package for a certain environment (GCC, kernel, libc). In order to handle GCC version incompatibilities and different kernel module build environments the package includes different branches (you can use the GCC_3.x.x subdirectory for GCC 4.x.x compiler versions).
