Happy xmas to all of You!
My question is how to prepare a hard drive (Practically a 256MB IDE disk on moudule) to run a linux installation on a machine which doesn't have a display card.
The only device which can be used as the standard output is the serial port on it.
My fist attempt was a DOS solution ( ctty command in the autoexec.bat) but how does it work under linux?
My final goal is to access the MBO via it's LAN interface and control relays/motors remotely in the future.
Any suggestions on the info how to change the console settings from the VGA card to a serial port on a linux boot disk at boot time are welcome

If I remember...

I think that you need a graphics card of some sort for most PC systems to boot. You don't have to use it, but the BIOS expects it to be present and it is a BIOS feature that cannot be overridden. However, you can use another system to boot something such as a server having no graphics(headless) Motherboards designed for server use may natively boot as headless.

Try to google linux headless to see if there is a workaround for directly booting a single PC linux system without graphics.

"Headless linux" google results seem promising, thank you!

Welcome...

Will you be so kind as to post back when you have some results of your project. I would be interested in learning more; headless linux is nothing I have used or needed so is nothing I have ever set up.
