Windows '98 Second Edition    
===========================
   1. Open Device Manager.

   2. PCI Multimedia Device will have a yellow marker the first time the
      operating system is installed.

   3. Select "Properties" on the yellow marker.

   4. Select the "Driver" tab.

   5. Click on "Update Driver".

   6. You will need the Windows Second Edition to complete the WDM installation.

      Controllers is:  Crystal WDM Audio Codec.

   8. A little Sound Icon appears on the Task Bar upon completing the
      driver installation.

Windows 2000
============
   1. By default, the Microsoft/Intel driver gets installed.  It is named  
      Intel ® 82801AA AC'97 Audio Controller.  Remove this entry from the
      Sound, Video, and Game Controllers section in device manager.

   2. Remove the corresponding Intel/Microsoft inf/pnp file in
      c:\winnt\inf.  The names of these files are wdma_int.inf and
      wdma_int.pnf.  It is, of course, optional that these get removed.
      But Plug and Play life will be easier if they are removed.

   3.  Restart. Plug and Play will occur again.  You will be prompted
       for a driver.
