    error in 'microcode revision guidance' Feb 20 2018


      I'm seeing an apparent mismatch between Public Name and CPUID on page 4.


      Intel® Atom® x5-Zxxxx CPU is listed as having CPUID 406C3

      Intel® Pentium® Processor N3xxx is listed as having CPUID 406C4


      However I have a Pentium N3700 which reports CPUID as 406C3, following excerpts from the listed command.
