VGA BIOS download function

The BIOS for the VGA must be downloaded, before a LCD is connected. This could be also a new LCD- dis-
play, which needs a corresponding VGA- BIOS.
Select the SHADOW option in the BIOS, for a BIOS and VGA (if this option is available).
-
Disable the EMM386 or other memory managers in the CONFIG.SYS of your bootdisk.
-
Make sure, that the FLASH520.EXE programm and the BIOS to download are on the
-
same path and directory!
Boot the DOS without config.sys & autoexec.bat -> press "F5" while starting DOS boot.
-
Is the empty diskspace, where the download tool is located, larger than 64kB (for safe storage)
-
Is the floppydisk 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 may can start in DOS mode by pressing the F5 key to disable the autoexec.bat and config.sys.
2. Run Flash520 -V lcd_file.000
3. If the bios download is finished you have to power off the system
4. Now the download procedure is finished
If the download does not work:
Check, if no EMM386 is loaded.
-
Check, if no peripheral card is in the system, which occupies the same memory range. Disconnect this
-
card.
If the download is stopped or not completed, make only a warm boot and repeat the steps or download
-
another file. As the video is may shadowed, everything is visible and a cold boot would clear the screen
and nothing would be visible afterwards.
If the screen flickers or is misaligned after reboot:
The previously loaded VGA- BIOS is not corresponding 100% or works only on the LCD properly.
-
If the screen is dark after the reboot of the system:
A new system BIOS must be programmed. Ask DIGITAL-LOGIC AG for the binary file.
-
If the previous version is still programmed:
Switch off the board and do not make a warm boot due to the fact that the data may are still stored in the
-
memory shadow.
