Thanks Mike and Cynthia for the feedback. Are the FMA diagnosis
engines only aware of AMD CPUs and the UltraSPARC III and above? Out
of curiosity, is there a reason that diagnosis engines weren't
developed for the UltraSPARC II CPUs (other than the CPUs being older
citizens in the SPARC community)?

Thanks again for the feedback,
