   | Note:The ethernet version is dependent on the MAU you are  |
   | using. There should be some indication of the ethernet     |
   | version on the MAU.                                        |

   |   Note:Segment length is the total length of cable between |
   |   the two farthest cards on the segment. Each card on the  |
   |   segment must have this option set the same.              |

   |   | Notes:If the card is on either end of a linear bus     |
   |   | network segment, the onboard terminator can be used    |
   |   | instead of using an external terminator.               |

   | 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.                                                  |
