Ahh bios sucks, feel the pain.
I lost my raid 1 mysteriously here on P5Q deluxe recently and now just use software backup as I lost data and had loads on downtime reloading everything. I dont know anything about raid so got frustrated and said F-it

If your in the market for a new board these P45 ones lose a wee bit of bandwidth, not much to average user, but with crossfired x2 cards you'll see it if anyone does (supposed to be a few percent as p45 does 2x x8 pcie2 rather than 2x x16 pcie1.1 - or simething along these lines)
Hey something that may help you meantime is software ive been using on my laptop for a few months with no problems, readdriverplus - it basically just selects disable driver signing upon boot up - I use it soley for running fangui on vistax64)
Its free, here's the website:
