  11. From what I know, 486 has six more instructions compared to a 386.
  12.  
  13. My question is, can't each of these instructions be simulated by
  14. a set of 386 instructions such that the functionality is not lost?
  15. This way we just need to write a parser which will go through
  16. the 486 specific executable file looking for these unique
  17. instructions and replace it with the equivalent set of 386
  18. instructions, thus producing a 386 specific executable file.
