3. File Summary:
CS4232C.EXE   	CS4232/CS4236 Configuration Program.  A DOS device driver used to initialize and configure the card.  It will download microcode from CWAUDIO.BIN.  Using the /X option, it will download resource data from RESOURCE.BIN.
CS32MIX.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.
CWAUDIO.BIN  	Data file containing microcode for the CS4232, CS4232A, and CS4236.  It is used by CS4232LD.VXD and CS4232C.EXE.  
CS4232.INI   	Default initialization parameters for CS4232C.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).  
CS4232.INF  	Windows 95 installation file.  It will install the files, update the registry, install CS4232C.EXE /W in the CONFIG.SYS, and it will install CS4232C.EXE /O /R in the DOS mode CONFIG.SYS.
CSFM.DRV	Crystal FM MIDI driver.
CWAUDIO.VXD	CS4232/CS4236 Windows 95 virtual device driver.
CS32BA11.DRV	CS4232/CS4236 Windows 95 wave, aux, and mixer driver.
CS4232LD.VXD   	CS4232/CS4236 Windows 95 Device Loader VxD.  This driver will download microcode from the CWAUDIO.BIN file.
SETUP.EXE		CS4232/CS4236 Install utility.  This executable will 
			remove the Crystal Drivers, clean up all the Crystal
			Audio registry entries and prompt for a reboot.

4. 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 order in which Win95 detects the Crystal logical devices:
d.Win95 detects the Crystal PnP Audio System Codec.  Win95 asks for the manufacturer's Disk.  Please select the approriate drive.  If the Windows default driver is not grayed out, installing DirectSound games replaces Crystal drivers with Microsoft Windows Sound System drivers.  
e.Win95 detects the Crystal PnP Audio System Joystick (Joystick in some platforms).
f.Win95 detects the Crystal PnP Audio System Control Registers (CS4232 Support Registers in some platforms.)
g.Win95 detects the Crystal PnP Audio System MPU-401 Compatible.
h.Win95 detects the Crystal PnP Audio System CD-ROM.  This device may not be found if the Plug and Play resources do not reference a CD.  If your audio device is not using the CD-ROM interface, this device will not be detected.
If any of the above (a thru d) 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.  

5. Uninstalling Crystal Audio Drivers
1. From Win95, run setup.exe provided in the Crystal installation diskette. The Setup will do an automatic cleaning up of the Win95 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 setup, the various CS4232 devices from the Control Panel should disappear.  It is recommended that prior to running Setup, remove the device entries in the Sound, Video, and Game Controller of the System Device Manager, and Crystal entries (if any) in the Other detected devices section of the Device Manager.
2. Shutdown and turn off your PC.  
3. Turn PC on, Start Win95, Win95 will now detect new hardware, create an information database, and proceed with the installation of Crystal device drivers.  

6. Dos Mode
To enable real DOS mode with CS4232/36 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\CS4232C.EXE /O 

7. Multiple Crystal Audio Cards
To enable a CS4232/36 audio card in a system that 
contains multiple CS4232/36 audio cards:
1.  Add the following option to the CS4232C.EXE 
    entry in the CONFIG.SYS.
    Device=C:\WINDOWS\CS4232C.EXE /W /Sxx
    where xx is the OEM ID number for the CS4232
    audio card to be enabled.
2.  The OEM ID number can be obtained from the

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
