Improper parallel port and video operation

PROBLEM - Improper parallel port (LPT1 only) and video operation. The conflicting addresses are I/O ports 3B8-3BB and I/O ports 3BC-3BF. When various video adapters are installed that address 3B8-3BB, the parallel port (LPT1) will also address the same address range causing improper function of the parallel port.

Machines AFFECTED - All 6382/S, 6384/D, and 6387/T which uses the monochrome port or a Weitek or Hercules video adapter.

SOLUTION - The work around for this problem is to reassign the parallel port device to LPT2, LPT3 or LPT4.
