Yes, thanks. I think I understand what you mean. Let's hope the MorphOS team will clarify what changed regarding the handling of the 2nd G5 CPU starting with MorphOS 3.10 and how that constitutes a "disabling", compared to leaving it enabled/idling on the one hand and compared to having it physically removed on the other hand.

(On a related note, it would also be interesting to know how the "disabling" of the unused PPC970 CPU compares to the powering down of the X5000's unused e5500 core(s)).
