No worries on it - I have the same board - turned out it's something that only works w/ Windows MCE - addition for Viiv or had to do w/ the "cool & quiet" total system power/fan control.
Sorry I don't remember exactly what it is, been a few months, but after a week of trying to find drivers for XP or other OS's I ran across articles indicating only MCE can use the feature right now...
(Clarification Edit) - was meaning to reply to the Intel 965WH MB question...
