fdisk? I haven't see that available since the ancient MS/IBM-DOS days,
or in Linux. What OS are you running on this computer?

I'm not sure the OS is important since the problems you describe are
accessing the BIOS or its POST screen not listing all your devices. The
POST screen presents its findings before any OS gets loaded.

Do you even see the POST screen? Or is the BIOS configured to display
some ad banner, like "Hey, you're using ASUS"? I'd get rid of any ad
banner display during boot up, and have the BIOS show its POST screen.
The ad banner is worthless. The POST screen shows valuable information.
