Hello,
We have a Linux 2.4 running on a Kontron Dimm-PC.
The system Software is not running properly, when we
let run it without a VGA graphic card module installed.
any idea for us?
Is there any Switch to ignore the Grafic card BIOS
Kindest regards
Nils Köhler

I think you should disable video support into the kernel and change kernel boot options in order to send console output to a serial port (ttyS0) instead of (tty0) for example. Kind regards

What do you mean by "System Software"? Linux Kernel, BIOS ?
You can configure Linux to use e.g. a serial port as console and you can remove the VGA console driver from the kernel. That should do the trick as far as Linux is concerned.
For the BIOS: most of them need a VGA card/Keyboard for the configuration dialog, so setting up the board configuration (and fixing it if there was, e.g. a CMOS checksum error ...) can only be done with a VGA card installed. Most BIOSes, however have an option where you can select wether a VGA/EGA card is "installed". I forget the names of the proper selections to be made, but this usually allows you to put the board into a mode where it will boot without a VGA.

There is a VGA card emulator with a serial port available. You plug this card into the PC, and it simulates enough of a VGA card to fool the BIOS. All output to the console is then converted to a normal RS-232 serial stream. I have forgotten the name of the company, but it should be in the archives.
