  3. Why do we need CPU information?<br>
<br>
  The X86 family started with the 8086 processor and grew as<br>
  enhancements were added.  Each processer added a few new<br>
  instructions that assembly programmers could utilize. When<br>
  these new instructions were used, the resulting programs<br>
  could not be run on older processors.
