I have a laptop mainboard, now I have connected it. How can I transfer the BIOS image or Windows installation to the monitor via Hdmi? Unfortunately I don't have a screen and only a woreless keyboard.
Hm - when you are in the BIOS, the functions of the operating system (Linux, Windows etc.) are not yet active. You are at the lowest level of computer functionality.
Be happy if your monitor shows anything at all. I can be wrong - but your wish seems impossible to me.
