Can there be created a different firmware for mother boards different than DOS [closed]

Maybe this is a dumb question but is something I need to know.
All laptops, computers, etc that i’ve used until today runs DOS as bios firmware… So I was wondering if there is motherboards running firmware that it is not DOS…?

Answer

You are a bit confused, I will try and keep this simple:

DOS is an operating system mainstreamed by Microsoft.

BIOS is an operating system (arguably) of very limited nature, that is typically stored as firmware on a motherboard. It is far less functional and complex, it just to “get things going” with relation to the hardware inside a computer, before starting up a boot loader.

BIOS is being phased out for UEFI these days.
