                            COMPATIBILITY MODE

           Setting                    JP2A                   JP2B

  Note:On some systems the data bus timing is not truly IBM PC/AT
  compatible. If the card is not initializing enabling compatibility mode
  may allow the card to operate properly.

       Note:In autosense mode the card automatically detects if it is in
       a 16-bit or 8-bit slot. On some Rev. 01 cards this jumper is
       incorrectly labeled TURBO.
