   * if the processor speed is 533 566 600 633, or it's a Celeron, the FSB is 66 

   * if the processor speed is 600 or 900, it could be 133 or 100 

    * if the processor speed is divisible by 3 and it's a Celeron, the FSB is 66 

   * if the processor speed is divisible by 3 and it's a PIII, the FSB is 133
