#3 - File Summary:
CWBINIT.EXE   	CS4236b/37b/38b Configuration Program.  A DOS device 
                driver used to initialize and configure the card.  
                It will download Microcode from CWBAUDIO.BIN.  
                Using the /X option, it will download resource data 
                from RESOURCE.BIN.

CWBMIX.EXE	DOS mixer used to set or adjust Sound Blaster mixer 
                settings.  It will run as a GUI application or as a 
                command line utility.

CWBAUDIO.BIN  	Data file containing Microcode for the CS4236B, CS4237B 
                and CS4238B.  It is used by CWBAUDIX.VXD and CWBINIT.EXE

CWBAUDIO.INI	Default initialization parameters for CWBINIT.EXE. It is
                only used if PnP is overridden (/O) or if not using the
                Win 95 option on a non PnP system (no /W).  

CWBAUDIO.INF	Windows 95 installation file.  It will install the files,
                update the registry, install CWBINIT.EXE /A in the 
                CONFIG.SYS, and it will install CWBINIT.EXE /A in the DOS
                mode CONFIG.SYS.  It should be modified by OEM's to meet
                their specific needs.  

CWBFM.DRV	Crystal FM MIDI driver.

CWBAUDIX.VXD	CS4236B/37B/38B Windows 95 virtual device driver.

CWBAUDIO.DRV	CS4236B/37B/38B Windows 95 wave, aux, and mixer driver.

CWB3DSND.EXE	CS4237B/38B 3D Audio Control Applet.  

CWBMIDI.VXD	Crystal MPU-401 MIDI virtual device driver.

CWBMIDI.DRV	Crystal MPU-401 MIDI Driver.

CWBPCPLE.DLL	Windows 95 Power Control Panel extension.  This file 
                will create an extension to the default Windows 95 Power
                Control Panel, enabling new features such as idle\
                time-out and power down now. This is not installed by
                default and requires a change to the install .INF.

CWBJOY.VXD	Crystal Digital Assisted Joystick virtual device driver.

UNINSTAL.EXE	Crystal Windows 95 uninstall program.  Running this 
                program will clean out any Crystal registry entries, 
                delete Crystal files, clean the CONFIG.SYS, and prompt 
                the user to restart.  When Windows 95 restarts, the 
                Crystal drivers should install using the default 
                Windows 95 installation.


#4 - General Information
     * The following feature changes have been made to the Version
       4.05.2600:
       1.  Direct X5 support has been added.
       2.  Crystal Soft Synth support has been added.
       3.  Support for the CS4232 and CS4236 audio devices has been removed.
       4.  Support for Brooktree's WaveStream has been removed.

     * Software Wavetable
       Crystal Soft Synthesizer is a General MIDI compatible music 
       synthesizer that runs within the Microsoft Windows 95 environment.
       It is a separate kit consisting of CSSYNTH.CAB, CSSYNTH.INF and a 
       readme file explaining how to install the software.  It requires 
       Direct X3 or greater. The MIDI Mapper has a new MIDI Output 
       associated with Soft Synth Called "Crystal Soft Synthesizer". 
       Crystal Soft Synthesizer can be selected to receive MIDI data from 
       any Windows 95 compatible MIDI application by selecting the MIDI 
       Mapper to "Crystal Soft Synthesizer".

#5 - Installing Crystal Audio Drivers
1.  Turn PC off and insert audio card into an ISA slot unless audio device 
    is present in your motherboard. 
2.  Turn PC on and start up Win95.
3.  Win95 is a PnP OS.  It automatically recognizes new PnP audio 
    hardware and creates a database for the hardware.  The following shows 
    the Crystal logical devices:
    A. Win95 detects the Crystal PnP Audio System Codec.  Win95 asks for the
       manufacturer's Disk.  Please select the appropriate drive and/or path
       to the driver files.  Installing DirectSound games may replace the
       Crystal drivers with Microsoft Windows default Sound System drivers.
       This problem can be solved by running the UNINSTAL.EXE application 
       and reinstalling the Crystal Audio Driver (see section 6).
    B. Win95 detects the Crystal PnP Audio System Joystick (Joystick in some
       platforms).  On certain versions of Windows 95, Windows will prompt 
       for the Win 95 CD in order to re-install the joystick drivers.
    C. Win95 detects the Crystal PnP Audio System Control Registers
       (CS4232 Support Registers in some platforms.)
    D. Win95 detects the Crystal PnP Audio System MPU-401 Compatible.
    E. Win95 detects the Crystal PnP Audio System CD-ROM.  This device may 
       not be found if the Plug and Play resources for the audio system do 
       not reference a CD.  If your audio system is not using the CD-ROM 
       interface, this device will not be detected.

       If any of the above (A through E) is not detected, a previous Win95 
       sound card installation was done.  For a clean reinstallation, the 
       user should see the Uninstalling Crystal Audio drivers section below.

#6 - Uninstalling Crystal Audio Drivers
1. From Win95, run UNINSTAL.EXE provided in the Crystal installation 
   diskette.  This application will do an automatic cleaning up of the 
   Windows 95 Crystal Audio registry entries.  Many problems with 
   reinstallation occur because of existing registry entries from previous
   installations and because of the \WINDOWS\INF\OEMx.INF files.  After 
   running UNINSTAL.EXE, the various Crystal devices should not be listed 
   in the Device Manager window.  
2. Restart your system.  If you want to remove or install any hardware, 
   select the SHUTDOWN option and turn off your PC.
3. Turn PC on.  Upon loading, Windows 95 will detect new hardware, create an
   information database, and proceed with the installation of Crystal device 
   drivers (see section 4)



#7 - Dos Mode
A.  Restarting the computer in MS-DOS mode.
    Shutting down to MS-DOS mode from the Shutdown Win95 Menu will 
    automatically run the CWBINIT.EXE /A in dosstart.bat.  Therefore, 
    shutting down to MS-DOS mode will automatically have the audio card 
    configured for Dos games.

B.  Enabling Dos support in Dos prompt icon.
    To enable real DOS mode with CS4232/36/36b/37b/38b support:
1.  Select a DOS prompt icon.
2.  Select Properties.
3.  Go to the Program tab.
4.  Select the Advanced... button.
5.  Click MS-DOS Mode.
6.  Click "Specify a new MS-DOS configuration."
7.  The following line will be automatically placed into the new 
    MS DOS configuration (with right path): DEVICE=C:\WIN95\CWBINIT.EXE /A


#8 - Crystal 3D Audio - CWB3DSND.EXE
     The 3D audio applet allows you to control the 3D audio features of your 
     audio system. The applet could control either the SRS(r) 3D Audio or 
     QSound(tm) 3D Audio depending on the specific audio device in your 
     system (CS4237B and CS4238B correspondingly). 

     The accessory runs each time you start your computer.  The corresponding
     3D audio icon appears in the notification area of the task bar. The task
     bar is where the Start button resides. The notification area is where the
     clock normally appears on the task bar. 

     The applet is activated by clicking with the left mouse button on the
     SRS(r) or QSound(tm) logo in the notification area (If you have trouble
     finding the accessory, move the mouse over each icon in the notification
     area until you find the icon with a tool tip that says "Crystal SRS 3D
     Audio" or "Crystal QSound 3D Audio"). You can also click on the logo
     with the right mouse button to see a menu with options for activating 
     the control "Settings", viewing the about box "About", or exiting the
     accessory "Exit".

     Note: You can also run the applet by clicking its icon from the 
     Programs | Accessories | Multimedia | Crystal 3D Audio Control 
     from the Start menu. 

     There are two sliders for controlling the sound of your 3D audio: on
     SRS(r) systems they are labeled Center and Space, on QSound(tm) systems
     they are labeled Volume and Space. Moving the slider toward the plus
     sign increases the effect, moving the slider toward the minus sign
     decreases the effect. You may find that you prefer different settings
     for different types of music. You can save up to 3 configurations using
     the preset buttons. You can disable your 3D audio by un-checking the
     Enabled check box at the bottom of the accessory.

     The three preset buttons, labeled 1, 2, and 3, allow you to save your
     favorite 3D audio settings. To activate the settings click on the preset
     button with the left mouse button. To store your settings, change the
     description of the button that appears in the tool tip, or to restore
     the button to the factory defaults click with the right mouse button on
     the preset button to see the menu of options.

#9 - Crystal Digital Assisted Joystick
     The Crystal Digital Assisted Joystick must be manually enabled for
     proper Digital Joystick configuration. This can easily be done by 
     opening the Joystick Properties in the Control Panel and selecting the
     Joystick configuration to Crystal Digital Assisted Joystick.
