Solved Trying to config. UEFI fw settings with BT keyb mouse!?!

[Saul]

I thought EFI was greatly heralded as "bringing BIOS into the modern era", making it possible to use BT keyb/mice etc.*
Can't for the life of me get the UI to respond, I need to change some settings, but it just won't recognise the mouse & keyb!
Any ideas, USB keyb's not an option, don't have easy access to one, same for mouse...

TY.
*among many other things ofc.

Nvm, thank freaking God I still have one, did a massive purge recently, unbelievable that it's still blood necessary. >.>
