Many of today's largest PC manufacturers build their systems on motherboards 
that come with an audio chipset built in and pre-installed.  If you try to 
install one of our soundcards in such a system, you will usually find that 
you now have resource conflicts resulting in malfunctioning audio or MIDI.

The best way to resolve these conflicts is to "remove" the built in audio 
from the motherboard.  This requires that the built in audio be disabled 
in the motherboard's BIOS (CMOS Setup Utility) *and* in the Windows 
operating system. 

You should perform these tasks *before* attempting 
to install your new Turtle Beach soundcard. 

NOTE:
Merely disabling the onboard audio chipset in the Device Manager will *not* 
be sufficient.  Even with the audio device disabled, it will still access 
the IRQ and other resources assigned to it. This will almost always result 
in a resource conflict with a second installed soundcard.

STEP ONE: Disable the audio chipset on the motherboard

Most of today's motherboards have a setting in the BIOS for 
ONBOARD AUDIO ENABLE/DISABLE.  Choose DISABLE for this setting. 
The exact implementation of this varies between manufacturers. 
Please read the documentation that came with your system or contact the PC
manufacturer's technical support representative for further information. 

Some older systems require that a jumper setting be changed on the
motherboard. Again, read the motherboard manufacturer's documentation 
or contact the PC manufacturer's technical support representative for 
specific instructions for your system.

STEP TWO: Remove the built in audio drivers and software 

In Windows 95/98:
-----------------

1.  Start Windows in Safe Mode by repeatedly pressing the F8 key as the system
    is running the POST at boot-up (when the silver letters on a black screen
    are displayed).  Then choose "3. Safe Mode" from the Windows 95/98 Startup
    Menu. 

2.  Open the Control Panel (Start > Settings > Control Panel). 

3.  Open the Add/Remove Programs control panel.

4.  If there is an uninstaller listed for the built in audio chipset, 
    run the uninstaller to remove the software for the built in audio chipset.

5.  Open the System control panel. 

6.  Click on the Device Manager tab.

7.  Scroll down to Sound, video and game controllers. 

8.  Select the icon for the built in audio device (if it's there). 
    Click on the Remove button to delete the device.

9.  Open AUTOEXEC.BAT in the System Configuration Editor 
    (Start > Run, type in sysedit and click OK). 

10. In the AUTOEXEC.BAT file, look for any of these lines (the exact text 
    will vary depending on what type of audio chipset is built into your 
    motherboard):

       SET BLASTER=... ... ...
       SET SOUND=... ... ...
       MIXERSET=... ... ...
       SET SNDSCAPE=... ... ...
       SET MIDI=... ... ...
       C:\ESSSOLO.COM
       C:\...\CWBINIT.EXE

    Anything like these may belong to the built in audio.  You will want 
    to disable these before installing the new soundcard.  You may need 
    to read the system documentation or contact your PC manufacturer's tech 
    support rep for more precise information on these files.  

    To disable lines in your AUTOEXEC.BAT file, type in the letters "REM" 
    and a space at the beginning of the line you wish to disable.  
    For example, this line: 

       SET BLASTER=A220 I5 D5 T4

    will look like this after you have disabled it properly:

       REM SET BLASTER=A220 I5 D5 T4

    The "REM" at the beginning of the line tells the computer to skip that 
    particular line. 

11. Repeat this procedure for lines in the CONFIG.SYS file that belong to 
    the built in audio chipset.  You may need to read the system documentation
    or contact your PC manufacturer's tech support representative for precise
    information on these files.  

12. Now shut down and reboot the system to normal Windows.  
 
    – If the system does not detect the onboard audio, then it is now properly
      disabled and you may now install your new Turtle Beach soundcard. 

    - If the system detects the onboard audio and prompts for the installation
      CD, then you will not be able to fully disable the onboard audio.  
      This may prevent you from installing your new Turtle Beach soundcard in 
      your PC without further assistance. 


In Windows NT 4.0
-----------------

You should first disable the onboard sound in the motherboard's BIOS Setup 
(CMOS Setup Utility), as previously described.  
Then in Windows NT:

First check in the Add/Remove Programs control panel to see if there is an
"Uninstaller" for the built in sound chipset.  
If this exists, run it.  If not, follow these instructions:

1. Open the Control Panel (Start > Settings > Control Panel). 

2. Open the Multimedia control panel.  

3. Click on the Devices tab. 

4. Open the Audio devices folder, and remove the built in audio device. 

5. Repeat this procedure for other components of the built in audio device, 
   such as the Mixer and MIDI devices.  Do not remove any MCI devices, 
   Codecs or other devices that are required components of Windows NT 
   Multimedia.  If you are in doubt about whether a device is safe to 
   remove, we recommend that you leave it in.  You may also wish to contact 
   the PC manufacturer's tech support rep or Microsoft Windows NT tech support
   for more detailed information. 

6. Shut down NT, and reboot.  If possible, you should remove the onboard audio
   chipset's driver files from 
       C:\Winnt\System32  and
       C:\Winnt\System32\Drivers.
   You may need to read the system documentation or contact your PC 
   manufacturer's tech support representative for precise information on these
   files.  


You should now be able to install your new Turtle Beach soundcard.
