I work in a second hand PC shop and we primarily get our stock from the government and businesses which means sometimes we get BIOS locked devices coming through, a colleague of mine found a way to remove the service tag off a Dell Optiplex 7080 and using that .bin put it on another 7080 which basically allows us to re-use this .bin on problematic 7080 models. My end goal is to have a catalog of .bin files in-case one fails a BIOS update or has some other BIOS problem.
