3.0 Installing Crystal Audio Drivers
--------------------------------------------------------------------------------

SoundFusion(tm) Driver Disk 1. Windows95 will detect the PCI
Multimedia Audio device. Push the NEXT button. The driver for the
"Crystal SoundFusion (tm) PCI Audio Accelerator will be found by the
Operating System. Press the FINISH button.
2. Again, Windows95 will request that you provide the Crystal
SoundFusion(tm) Driver Disk 1. Press the OK button to continue, then
type A:\ and press the OK button.
3. Next, Windows95 will detect the CS423x device. Press the NEXT button.
The Crystal PnP Audio System CODEC driver will be found. Press the
FINNISH button.
4. The operating system will prompt you to provide the Crystal
SoundFusion(tm) Driver Disk 2. Please insert this disk and press the
OK button to continue. Then type A:\ and press the OK button.
5. Finally, you will be prompted for the Crystal SoundFusion(tm) Driver
Disk 3. After inserting this disk, press the OK button to continue.

--------------------------------------------------------------------------------
4.0 Uninstalling or Updating Crystal Audio Drivers
--------------------------------------------------------------------------------
1. From Win95, run SETUP.EXE located in the Crystal SoundFusion(tm)
Driver Disk 1 and select Install or Uninstall. 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 SETUP.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 (as described in the previous section)
