   Bus/CPU Speed MHz Setting   
      
   Is there a reason why the board component outline follows the arcane IBM   
   location diagram, instead of the [sl]eazier to understand method used on   
   the Ardent Tool?   
      
   Example:   
   2 (J15) Modem Ring Detect connector   
      
   How about:   
   J15 Modem Ring Detect connector
