   | Note:The boot ROM socket can contain a BIA ROM or a boot   |
   | ROM. The BIA ROM provides the node address if a boot ROM   |
   | is not installed. If the ROM memory is disabled, the node  |
   | address must be set using the RTR16ASI.SYS device driver.  |

   | Note:LLC allows the card to access networks using the ISO  |
   | and SNA protocols. (e.g. IBM PC LAN,IBM 3270 terminal      |
   | emulation, and AS400)                                      |

   | The card has built-in LLC support on the two ROMs above    |
   | SW1. To allow for future compatiblity and upgrades you can |
   | load the LLC code into the onboard RAM.                    |
