   Special Driver Installation Requirements on Windows 2000
   ========================================================
        Microsoft has put file protection for drivers in the newer builds of
        Windows 2000.  To get around the file protection and install the WDM
        Inky driver you should perform the following steps.

        · Disable file protection.
	  To disable the system file protection change the following 
	  registry key. Section: 
     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
     Entry: SFCDisable Value: 0x00000001

        · Remove the children of the SoundFusion driver using the 
          system properties panel.

        · Remove the SoundFusion driver using the system properties panel.

        · Remove all inf's that have cwcspud.sys in them.  
          (wdma_csf.inf and any oem*.inf's)

        · Boot to dos using a windows 98 Boot disk.
          Go to the Winnt\system32\drivers directory.  Type "Del cwc*.sys"

3.  Uninstalling or Updating Crystal Audio Drivers
--------------------------------------------------------------------------------

   Driver Uninstallation procedures for Windows 98 and Windows 2000:

       the driver must be done through the Device Manager.  This is done by 
       highlighting the main Crystal Soundfusion Device, and following the
       procedures outlined below:

       a. For Windows 98 -  Press remove button in Device Manager.

       b. For Windows 2000 - Do a right click on the Crystal Soundfusion 
          Device, and choose uninstall.
