    About CPUID and Stepping

      CPUID Function1,EAX[3:0] Specify the CPU stepping,but there is not a formula that I can follow from Nehalem processor.



      I want to know is there any document or table: a  CPUID corresponding to the stepping


      such as :CPUID: 106A0h  Stepping: A0

                               20652h                 C2

                               20655h                 K0
