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.

3.  Select the Unlisted or Updated Driver entry and press OK.
