5) Installing The Crystal Audio Driver: 
   1.  	If  hardware is to be install, insure that the system is powered off 
	first.  If there is another audio card, please remove it before 
	installing the Crystal card.    If necessary and if possible, disable 
	any motherboard installed audio CODECs  (consult appropriate system 
	documentation for disabling hardware, and removal of software from the
	system).
   2.	Install the Crystal codec based card , e.g. CRD4232-3 or CRD4236-3 
	(if appropriate), and power on the system.
   3.   Copy the files on the diskette to a directory on the hard drive, or 
	you may install from floppy.
   4.  	Double click the MULTIMEDIA icon in the control panel. The Multimedia 
	Properties windows will appear.  Click on the Devices tab and press 
	the Add button.
   5.  	Select Unlisted or Updated Drivers  by placing the mouse pointer over
	it and clicking the left mouse button.  Press the OK button.  A dialog
	box will appear and request the path of the location of the drivers to
	be installed.  Enter A:\ if you are installing the driver from a floppy
	disk.
   6.  	The label CrystalWare Audio Driver  is displayed on the dialog box.  
	Press OK. 
   
   WindowsNT may report that any of the driver files are already present in 
   the system.  Please select the NEW button to ensure a complete installation.
   The CrystalWare Configuration Panel may be displayed during the installation.
   If the system supports Plug and Play, showing this window can be optional by 
   making a change in the CSPNP.INF file.  Please refer to the Software OEM 
   Reference Manual document for more details on how to customize this file.  
   On the other  hand, if the system does not support  Plug and Play, the 
   configuration panel is displayed to allow the user to select the configuration 
   resources that should be allocated to the audio part. You must select non 
   conflicting resources. Otherwise, your system will be unable to function 
   properly.  WindowsNT Diagnostics will show you the resources allocated to the
   different devices in the system. To access this utility select the 
   Administrative Tools Group from the Programs option in the Start Button menu 
   and click on the WindowsNT Diagnostics.

   After completing the driver installation, Windows NT may display a dialog 
   box asking you to restart your system.  In order to make sure that the 
   installation is complete, press the Restart Now button.

   To remove the drivers from the system, please follow these steps:

   1.	Double click on the MULTIMEDIA  icon in the control panel.  Select the 
	Devices tab and double click on the  Audio Devices entry.   Select the
	driver by clicking the left mouse button over its name.  Press the 
	REMOVE button.
   2.	A question box will appear to verify your decision.  Press the YES 
	button.   A warning message will prompt you to restart WindowsNT.
