            Notes:Node address 0 is used for messaging between nodes and
            must not be used. A total of 255 node address settings are
            available. The switches are a binary representation of the
            decimal node addresses. Switch 8 is the Least Significant Bit
            and switch 1 is the Most Significant Bit. The switches have
            the following decimal values: switch 8=1, 7=2, 6=4, 5=8,
            4=16, 3=32, 2=64, 1=128. Turn Off the switches and add the
            values of the Off switches to obtain the correct node
            address. (On=0, Off=1)

       Note:A 16-bit VGA adapter typically decodes base memory in 128KB
       blocks. If you are installing the NIC in a system with such a
       card, you may need to set the NIC block decode size to 128KB. If
       you set the block decode size to 128KB then all other adapters in
       the system must also utilize 128KB decode.

       Note: Enhanced mode optimizes performance and minimizes conflicts
       of your hardware by using a Thomas-Conrad ARCNET driver. It is
       also not necessary to set the I/O address. In compatible mode the
       adapter can use most existing ARCNET drivers.
