Hi! You misunderstood me... USB is SLOWER than PS/2, so my recommendation was to use PS/2 keyboard and mouse! But you had those already.
If you switch off legacy USB support in the BIOS, you must use PS/2 keyboard for your BIOS setup again. Because, as you noticed, USB keyboard will not work if you disable the BIOS "legacy" USB driver. I hope that answers your question.
