4.7.5 VGA BIOS Download Function
The BIOS for the VGA must be downloaded, before an LCD is connected. This could be also a new
LCD-Display, which needs a corresponding VGA BIOS.
The following points must be checked before downloading a BIOS:
- Select the Shadow option in the BIOS for 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 DOWN_000.EXE programm and the BIOS to download are on the
same path and directory!
How to download a VGABIOS:
1. Restart the system with SHADOW enabled and no EMM386 loaded.
2. Check if you find the DOWN_000.EXE and also the *.000 files on your disk to download.
3. Refer to the VGABIOS.DOC for more information about the VGABIOS files.
4. Insert the floppydisk with the program DOWN.EXE and all VGA-Drivers.
5. Start DOWN_000.EXE.
6. Check if the DOWN_000 program has identified the product and the shadow correctly.
7. Select the function PROGRAMM VGA-BIOS.
8. Select the VGA BIOS out of the proposed file list (UP/DOWN arrows) and press ENTER.
9. Check if the new VGA-Header is displayed on the VGA-INFO screen.
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 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.
