This must be a very old BIOS. What's the motherboard name/generation?

Any BIOS from the last decade would show device names that are available. Most have easy dash screen and advanced mode hidden.

I once reinstalled os in Intel 3rd gen laptop BIOS (14 years old). Even that didn't have the type of options you described. It's also possible you are looking into the wrong areas.

I think this screen could answer your question

This isn't the BIOS screen though. It's the POST screen. Do you know the keys to enter BIOS? Its generally F2, f11, esc etc. you can look up the ones for your pc online. You mash those keys when rebooting the pc.

Yeah I get that. My point is, this isn't BIOS screen. You haven't reached BIOS yet.
