Note: The following does NOT apply to Win 95a.

When Windows 95 revision B (aka OSR2 or 95B) and Windows 98 detect the Tropez
Plus card, they do not install the correct Tropez Plus drivers (version 1.1) 
that should be installed from the driver disk.  Instead, Windows installs 
default Crystalware audio and MPU-401 drivers. 

1) Remove these (Crystalware) drivers.
2) From the system, completely remove the corresponding Windows .INF file 
   that holds information about Crystalware, so that Windows stops detecting 
   it as this. 
3) Power down the system and set the JP2 jumper (the IDE Controller) on the 
   Tropez Plus in the OFF position, to avoid conflicts. 
4) Make sure that at least two other IRQs are available. 
   Note: On some newer systems, some IRQs may appear to be 
     available, but they are not.
