I've spent all day trying to do this. All I have so far to show that it recognizes the other 2 cores is in AOD. When you enable ACC then go to AOD and select "per core" in the ACC menu it will show 4 cores. I will continue to fiddle with it untill I reach a conclusion. Maybe we can figure this out.
