Built my rig a few days a go and everything is going pretty mint. A few little niggles but hey when isn't there. What's really bugging me though is I cannot enter BIOS with my Filco Majestouch Ninja over PS2. The same keyboard works fine in USB but no luck over PS2. Not a big deal, more of an annoyance really. Is entering BIOS with a PS2 keyboard playing up for anyone else with a Maximus V Extreme? Maybe more importantly if it is working for you, what BIOS are you on?
