Issue:
How do I remove all driver information for my Affinity (DCI) adapter?

Solution:
1.   From within a DOS windows type
:                        CD\WINDOWS\SYSTEM

     Then delete the following
:                  C:\WINDOWS\SYSTEM\xxx5250.VXD   (xxx = DCI, AFF or CEM)
                  C:\WINDOWS\SYSTEM\xxx5250.386   (xxx = DCI, AFF or CEM)

2.   From within a DOS window type
:                  CD\WINDOWS\INF

     Then delete the following
                  C:\WINDOWS\INF\DRVDATA.BIN
                  C:\WINDOWS\INF\DRVIDX.BIN   

3.   At the C:\WINDOWS\INF prompt type
                  DIR OEM*.INF

****NOTE:   Newer versions of Windows95 may have a different format for
            the .INF file.

            Look for C:\WINDOWS\INF\OTHER\DEVELO~x.INF and delete it
                  Or C:\WINDOWS\INF\OTHER\AFFINI~x.INF and delete it
                        (Where x is a number)

     Display the contents of each OEMx.INF file and delete any file that
     relates to DCI or Affinity.
