I think I vaguely remember something about that, but I would be pretty upset if the keyboard navigation was unusable. It is almost as bad as the stupid mouse enabled BIOSs that never work. It doesn't even work on the Dell laptop I have for work. The keyboard navigation is always extra special in those cases and involves a lot of button mashing to get to the correct thing, if I can figure it out at all.
I don't use wired mice either and had to dig the old gaming mouse out recently so I could get to some menus on a new machine to pair the mouse. I have done the mouse pairing thing through console and it isn't the best experience, especially if you are trying to figure out if things are working in the first place. For me, I could figure it out. For a new user, you are asking a lot.
Just give me an old school OS installer with simple menus, easy keyboard navigation, and the bare minimum guidance needed to not entirely fuck it up.
