Revolt cab, Immersion board issue

[ASI]

Hi Guys,
            Hoping someone may be able to help out with this problem.
I have a revolt cab ( had a fault with pc booting when i got it, but sorted that with new HD)
If i connect a standard windows xp drive up installed the immersion drivers for the FF board.
Tests ok for wheel & pedals, But when reconnect the original drive, wheel tests fine, but
not the pedals. Any ideas where to look next.
Cant boot into windows with original drive, as set to go direct to game.

Thanks for all the info posted on this thread, has help out a lot so far.
