                              OPERATION MODE

                 Setting                                JP1

  »            Interrupt mode                    Pins 2 & 3 closed

                 Polled mode                     Pins 1 & 2 closed

  Note:This option controls the interface between the CPU and the UART on
  the card. Polled mode should only be used in IBM 3270 PCs.

                               NETWORK SPEED

                 Speed                                 JP2

  »               600Kbps                       Pins 1 & 2 closed

                  300Kbps                       Pins 2 & 3 closed

  Note:The LAN speed must match that of the 68B server.

                 System clock                    Pins 2 & 3 closed

  Note:If the card is installed in a 4.77Mhz PC either setting can be
  used. If the card is installed in an AT or compatible, or a Turbo PC
  the system oscillator setting must be used (Pins 1 & 2 closed).

                            MISCELLANEOUS NOTES

  This card comes in two versions. One version addresses the boot ROM at
  D0000h while the other uses address C0000h for the boot ROM.
