Fix for: What does "cpuid level" mean?

Low Risk

most of the information that is displayed is obtained from the x86 instruction 'cpuid'. The 'level' is the maximum option set that you can safely use to interrogate the processor for information. The Intel app note at http://www.intel.com/assets/pdf…
