  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 1 is the Least Significant Bit and switch 8 is the Most
  Significant Bit. The switches have the following decimal values: switch
  1=1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=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 drive. It is also not
  necessary to set the I/O address. In compatible mode the adapter can
  use most existing ARCNET drivers.
