   | Note: Up to four NICs can be installed in a single system. |
   | If more than one card is installed, each card must have a  |
   | different Identification number.                           |

   |                NETWORK SEGMENT LENGTH NOTES                |
   |------------------------------------------------------------|
   | The segment length is automatically detected and           |
   | configured on this card, but may not be on other cards on  |
   | the network segment. All NICs on the network segment must  |
   | have this option set the same.                             |

   |                    DATA BUS SPEED NOTES                    |
   |------------------------------------------------------------|
   | On some systems the data bus timing is not truly IBM PC/AT |
   | compatible. If the card is not initializing, Changing the  |
   | data bus speed from 'Normal' to 'Fast' may allow the card  |
   | to operate properly. To change the data bus speed you must |
   | use the ICRCNFIG utility that comes with the card.         |

   |          BOOT ROM/CHECKPOINT SECURITY CHIP NOTES           |
   |------------------------------------------------------------|
   | The boot ROM socket accepts an 8K boot ROM or a CheckPoint |
   | security chip. The CheckPoint security chip supplies virus |
   | protection, access control, and access logging functions.  |
