                   I/O cycle

       Note:If the card is installed in a fast computer, the card may
       need to slow down the I/O cycle by adding wait states.

                            COMPATIBILITY MODE

                 Setting                               SW1/7

  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.
