KTD-S0023-A Page 3 BIOS Update

2 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 IPLXUPD.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.

COMMAND.COM must reside in the same directory or alternatively there has to be a valid path in the

Note:
variable COMSPEC.

The syntax of the DOS update tool is:

IPLXUPD /C /R <BIOS filename>

/C = destroy CMOS checksum
/R = warmstart after programming

Following combinations are valid:

IPLXUPD <BIOS filename>
IPLXUPD /C <BIOS filename>
IPLXUPD /C /R <BIOS filename>

2.1 Known Restrictions

When a USB drive (e.g. a key) is used for the Bios update it is recommended to switch off the power supply
after the update process. Reason: after a warmstart sometimes the Bios does not detect USB drives.

3.1 LCD/LVDS Technology Overview

3.1.1 Detailed Timing Descriptor (EDID or DisplayIDTM)

The input fields Pixel Clock, Horizontal Active, Horizontal Blank, Horizontal Sync Offset, Horizontal Sync
Width, Vertical Active, Vertical Blank, Vertical Sync Offset and Vertical Sync Width must be filled in with the
correct values according to the panel’s data sheet. In many cases the value for Horizontal/Vertical Blank
cannot be read directly from the data sheet. Instead terms such as Display Period (active pixels/lines) or
Horizontal/Vertical Total appear.
In this case the following calculation can be made:

⇒ Blank Value = Total Value – Active Value.

Sometimes the datasheet does not specify Sync Offset and/or Sync Width. In this case the permissible
values can only be determined though testing. However the rule is:

⇒ The sum of Sync Offset and Sync Width must not exceed the value for Horizontal/Vertical Blank.

Also datasheets are often different for displays with double pixel clock. If Pixel Clock and Horizontal Values
seem to be halved this must be corrected for input:

⇒ The values must always be entered as though it were a panel with single pixel clock.

Example 1:

PRIMEVIEW PM070WL4 (single pixel clock)
Data sheet specifications:
Clock Frequency [typ.] 32 MHz
HSync Period [typ.] 1056 Clocks (equivalent to Horizontal Total)
HSync Display Period [typ.] 800 Clocks (equivalent to Horizontal Active)
HSync Pulse Width [typ.] 128 Clocks
HSync Front Porch [typ.] 42 Clocks
HSync Back Porch [typ.] 86 Clocks
VSync Period [typ.] 525 Lines (equivalent to Vertical Total)
VSync Display Period 480 Lines (equivalent to Vertical Active)
VSync Pulse Width [typ.] 2 Lines
VSync Front Porch [typ.] 10 Lines
VSync Back Porch [typ.] 33 Lines

Result:

Pixel Clock 32
Horizontal Active 800
Horizontal Blank 256 ((128 + 42 + 86) → H. Pulse Width + H. Front Porch + H.
Back Porch)
Horizontal Sync Offset 42 (H. Front Porch)
Horizontal Sync Width 128 (H. Pulse Width)
Vertical Active 480
Vertical Blank 45 ((2 + 10 + 33) → V. Pulse Width + V. Front Porch + V. Back
Porch)
Vertical Sync Offset 10 (V. Front Porch)
Vertical Sync Width 3 (V. Pulse Width)

Horizontal Display Period 640 Clocks (equivalent to Horizontal Active)
Vertical Period [typ.] 1066 Lines (equivalent to Vertical Total)
Vertical Display Period 1024 Lines (equivalent to Vertical Active)

Result:

Pixel Clock 108 (2 x 54 MHz)
Horizontal Active 1280 (2 x 640 Clocks)
Horizontal Blank 408 ((844 – 640) x 2 Clocks)
Horizontal Sync Offset 45 (normally approx. 10 – 15 % of Horizontal Blank)

Horiz. Valid [typ.] 640 Clocks
Horiz. Back Porch [typ.] 124 Clocks
Horiz. Front Porch [typ.] 24 Clocks
Vsync Period [typ.] 1066 Lines
Vert. Valid [typ.] 1024 Lines
Vert. Back Porch [typ.] 38 Lines
Vert. Front Porch [typ.] 1 Line

Result:

Pixel Clock 108 (2 x 54 MHz)
Horizontal Active 1280 (2 x 640 Clocks → Horizontal Addr. Time)
Horizontal Blank 408 ((844 – 640) x 2 Clocks)
Horizontal Sync Offset 48 (2 x 24 Clocks → Horizontal Front Porch)
Horizontal Sync Width 112 (((408/2 – 124 – 24) x 2) → H. Blank – H. Back Porch – H.

3.2 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. The Detailed Timing Descriptor (18 bytes) is the most important field. No 24bit panels (FPDI/LDI)
are supported though. This means EDID should only be used for 18bit panels.
For further information please consult the official EDID specification from the VESA comitee which has to be
payed.

3.3 DisplayID

TM

Specification (VESA)

Intended as a replacement for all previous EDID versions DisplayIDTM contains many new features. It's a
structure with several well defined elements (tags). Not every element that is listed in the specification has
to be part of the resulting data set (basic section).
KONTRON has decided to use this selection of tags (mandatory presence).

Tag Description

00h Product Identification Data Block (Vendor ID, Product Code, Manufacturing Date ...)

03h Type I Detailed Timing Data Block (Pixel Clock, Horizontal/Vertical Data ...)

0Ch Display Device Data Block (Device Technology, Operating Mode, Color Depth ...)

0Dh Interface Power Sequencing Data Block (Power On/Off Timing)

0Fh Display Interface Data Block (Interface Type, Interface Attribute ...)

3.3.2 DisplayIDTM Restrictions

Depending on the graphic controller not all features can be used. The following table shows the most im­portant restrictions.

Restrictions for KTLX800/pITX

Panels with dual or quad clock not supported (2 or 4 Pixel per Clock)

Many displays center the picture automatically using the DE-signal. In general the picture is centered
automatically in horizontal direction but some displays also center the picture vertically using this signal.
Only for displays that can be driven with a
these information please check the datasheet. With the KTLX800/pITX board the parameters for the typical
detailled timing out of the datasheet might not be correct for centering the picture. In general the exact
positioning of the picture has to be obtained experimental.

3.3.3 LCD Panel Selection

The choice of an LCD display is basically defined by two parameters.

Pixel Clock Range 20 MHz - 135 MHz

Currently this leads to a maximum resolution of

With the AMD graphic driver it is not guaranteed that every resolution can be achieved. KONTRON does not
guarantee the correct function of the board for untypical resolution. In principal the use of DisplayID
allows realizing every special display resolution. For this a valid DisplayID
onboard EEPROM. Additionally the BIOS Setup entry

must be set to Auto.
Many displays with a resolution up to XGA (1024 x 768) have a digital (TTL) interface. KONTRON offers a
special adapter to connect these displays to the LVDS interface (KAB-ADAPT-LVDStoTTL with part number

61029).
