A note about 83+BE ports: On the 83+BE, many of the ports have been mirrored to the 00h-07h region. If a port is mirrored, when it is being read, take the bitwise-AND with 07h to find the actual port being accessed. All write to mirrored ports are ignored.

Legitimate 83+BE ports (the rest are mirrored):

  • Read values - 00h-07h and 10h-13h are original ports
  • Write values - 00h-07h, 10h-13h, 14h, and 16h are original ports
