I just tried to use original VGA BIOS got by dd command. There is no VGA output with this VGA BIOS.
What is OptionRom? Where do you get it from? And why does it work when original VGA BIOS doesn't?
Or, do I not have original VGA BIOS? Is there any possibility to control my VGA BIOS?
So many questions, I hope at least some of them could be answered here.
Greetings Klaus
