Does this adaptor REQUIRE any special driver software to be run? For example, if I boot into the early startup menu, will I be able to use a PS/2 mouse or would I have to plug in my old Amiga mouse.
Well, ps2m adapter does NOT require special driver to run and works perfectly in the early-startup menu as well as in any game. The only driver you need is a wheel driver.
Assuming Elbox to have a bit of common sense, their controller should perform in the same way...
