Q: Partial or no sound in a Window's Multimedia program (Myst, Microsoft 
   Bookshelf, etc.) or unable to enter Windows after running the 
   'switch drivers' application.

A: The Monte Carlo "V-Synth" mode may not be compatible with the software.  
   While the V-Synth mode will support superior midi playback, it is not 
   optimized for digital audio.  Switching to Standard mode will take care 
   of most of the compatibility issues with Window's games.

   Procedure:

     1. Edit the system.ini (either through windows or in the DOS editor)
     2. Find the [Sndsys.drv] section
     3. Change the Interrupt to something other than 7 (5,9,10,11,12)
          If there is no network card in the system, 10 is the best choice.
     4. Change the line that says:
          OldMSDosGameCompatibility=1 to =0
     5. Save the changes and reboot
------------------------------------------------------------------------------

Q: I keep getting stuck during the installation.
A: Follow the directions above.  Until you make these changes, you will not 
   be able to complete the install.  Don't be too quick to re-install.  
   Many problems can be take care of with simple edits rather than complete
   installations.

Q: Error messages in DOS or when entering Windows
A: Below are the most common, tested settings for a Zeos Pentium.

BIOS:  

     1. Set the LPT1 setting under Integrated Peripherals back to 'Auto.'  
        For the settings below, it is not necessary to disable the Parallel 
        port interrupt.
     
     2. Make sure that Audio Port or Audio Device is set to 'disabled'

MCACDOS.INI

     [MAD16]
     MIDI=ENABLED
     MIDI_IRQ=5
     MIDI_PORT=330

     [SBPRO]
     PORT=220
     IRQ=5             *or 10 if network card is not installed.
     DRQ=1

     [WSS]
     PORT=530
     IRQ=10*           *unless network card is installed. 11 can be used 
                        if no SCSI chip.
     PDRQ=1
     CDRQ=0

System.ini

     [sndsys.drv]
     IOAddress=530
     Interrupt=10      *unless network card is installed...other choices: 
                        5 or 11
     DMAADC=1
     DMADAC=1
     DUPLEX=Half
     OldMSDosGameCompatibility=0

     [mad16c.drv]
     IOAddress=530
     Interrupt=10       *same as above

The next section depends on the card.  You will have ONE of the following two 
sections:

     [m16midi.drv]
     interrupt=11       *unless SCSI chip is installed...other choices: 
                         5,7,10
     installed=1

or

     [mpu401.drv]
     int=5              *This setting can also be at 7
     port=330
------------------------------------------------------------------------------

Q: Computer locks when trying to execute the 'mcmode' line in the config.sys.
A: This is probably due to a video IRQ conflict in the MCACDOS.INI file.  
   'F5' past the config.sys and autoexec.bat file and edit the 'mcacdos.ini' 
   file in the mcarlo directory.  Check the following settings:

   If MIDI=ENABLED, then make sure that the line below that says MIDI_IRQ is 
   set to something OTHER than 9.  Setting this to 7 will allow the computer
   to boot properly. Also, make sure that the IRQ in the [WSS] section is not
   at 9.
------------------------------------------------------------------------------

Q: Error message, "CS4231 not present," after executing the mcmode.exe line.
A: The incorrect install software may being loaded for the card.  Contact the 
   vendor who you purchased the system from or download the correct drivers 
   from the Turtle Beach Web site.
------------------------------------------------------------------------------

Q: Partial or no sound in DOS games.
A: Make sure that if it is a S.B. compatible game, that the Monte Carlo is in 
   the S.B. mode by typing:
       mcmode -s

   The card will stay in S.B. mode until it is changed to WSS mode by typing:
       mcmode -w

   Sometimes it is necessary to "refresh" the driver between games.  This 
   can be done by running the mcmode line before entering a new game.

   Also, change the S.B. interrupt to 5 instead of 7.  This will avoid any
   sharing conflicts with the Parallel port. Also change the "Set Blaster"
   line in the Autoexec.bat to match the change (i7 to i5)

   Other Considerations:
   ---------------------
   With the earlier Monte Carlos there is an additional file that may help 
   with game compatibility. The mcsbmix.exe file can be run from the c:\mcarlo
   directory and may yield improved S.B. pro emulation.  This can be put in
   the Autoexec.bat or run separately.  
------------------------------------------------------------------------------

Q: Error code 266 when trying to play an audio CD through TBCD or the Sierra 
   Audio Rack.
A: Two possibilities:

   1. Make sure that the [MCI] CD-Audio driver is loaded in drivers in the 
      Control Panel. If it is not on the list, click on the 'add' button and 
      choose it from the list.  You will      be prompted to insert one your 
      original Windows disks.  The driver will then be loaded and you will be 
      able to play an audio CD.
   2. This same error will occur when trying to access TBCD or Sierra 
      without an audio CD in the CD-ROM drive.
------------------------------------------------------------------------------

Q: Static or noise in Dos and/or Windows
A: Depending on how your software was setup, you may have an internal feedback
   loop that is causing extra "static" in the DOS environment.  This can be
   quickly fixed by going to the c:\mcarlo directory and typing:
         mcacmix c=70

   This will bring the volume of the FM synthesizer down to a level that will 
   not create the feedback.  You should only need to do this once, as the new
   settings are saved automatically.

   Also, make sure that you are using the Line Out and NOT the Speaker Out if
   using powered speakers.
