Is there a table somewhere that will take the information in the CPU Family field in the NTCONFIG record (i.e., X86 FAMILY 15 MODEL 2 STEPPING 7 ) and convert that to a specific processor chip manufacturer name and model?

The short answer is that Intel knows what these things means, but does not publish a mapping anywhere of how these internal names correspond to external products. The closest Intel comes is this document at http://www.intel.com/design/chipsets/mature/mature.pdf, which does not mention either Family or Stepping names. In semiconductor fabrication, “stepping” refers to the chip manufacturing process […]
