PART 3 - CD-ROM Drive Interface

        Interfacing a CD-ROM drive to your Sound Card:

        To interface/connect your new or existing CD-ROM drive to your
        sound card, please follow the simple steps below.

        If you are interfacing an existing CD-ROM drive to your sound card,
        you only need to follow steps 1 and 2 below since you should already
        have your existing CD-ROM driver setup in your CONFIG.SYS file.
        However, if your are interfacing a new CD-ROM drive, you will need
        to follow all 3 steps below; in which case, it is recommended that
        your perform step 1 first.


        1. Hardware setup

           To connect your CD-ROM drive to your sound card, you will need
           to setup the correct data connector cable from your CD-ROM to
           your sound card. Please refer to your sound card installation
           manual for more details.


        2. Modifying/Setting the MAD16.SYS setup program

           To interface your new or existing CD-ROM drive to your Sound Card,
           use an editor to open the CONFIG.SYS file for editing and locate
           the line "BASEDEV=MAD16.SYS..."  This line should be at the first
           line of the file. Insert the following "CDTYPE:" option into the
           line and when completed, it should read:

           BASEDEV=MAD16.SYS CDTYPE:X CDBASE:XXX CDIRQ:X

           where <model> is the CD-ROM model denoted by the following characters:
                       S       - stands for SONY
                       M       - stands for Mitsumi
                       P       - stands for Panasonic
                       I       - stands for IDE (secondary)

           For example, the following enables the interface for a SONY IDE CD-ROM.

           BASEDEV=MAD16.SYS CDTYPE:I CDBASE:170 

           If the above MAD16.SYS line is not located, proceed to PART 1 of
           this document for details on installing the Sound Card setup program.

           Save the file and proceed to install the CD-ROM driver if needed.


        3. Installing the CD-ROM driver

           Open the Selective Install program located in the System Setup
           folder and click on the icon next to the "CD-ROM Device Support"
           entry.  A window with the list of OS/2 supported CD-ROM drivers
           will appear. Select (click on) the CD-ROM driver name belonging
           to your CD-ROM model and click on OK to confirm. Click on OK to
           start your CD-ROM driver installation.

           If you have already successfully connected your CD-ROM drive
           to your sound card as detailed in your installation manual, you
           may shut down OS/2 and reboot your system for the changes to
           take effect. If not, please proceed to connect your CD-ROM drive
           to your sound card after shutting down OS/2 and switching off
           your system.



           List of CD-ROM drive models supported by your Sound Card:

                  NOTE: The WSS IRQ and DMA are specified here, but can be
                  reset by the audio PDD when it loads.  Optimally, the
                  audio PDD will query MAD16.SYS to learn of the device settings.
                  As of this writing, this communication does not exist.
        
        JOYSTICK: 0, 1  (default 1, joystick enabled)
        
        MPU:      Y, N
        MPUBASE:  330, 320, 300

                  NOTE: MPU401 setting are optional settings.
                        See Part 7 for more MPU401 descriptions.

PART 5 - How to Reconfig the Hardware Settings

        Type "c:\sound16\minstall" and enter, then follow the directions from
        Part 1, step 8.  Directory "SOUND16" was created in root directoy during
        the first installation process.  It contains the same files as the 
        installation disk.

PART 6 - WIN-OS/2 support 

         Run MINSTALL and select OPTi WIN-OS/2 Audio Driver to install for
         WIN-OS/2 support.
         Before starting a WIN-OS/2 session, be sure to close all OS/2 Audio
         applications.

PART 7 - MPU401 support

         MPU401 interface is currently supported under WIN-OS/2 environment
         only. By default, MPU401 interface is disabled. MINSTALL does not 
         add any MPU401 hardware settings in config.sys. To run MPU401 
         applications under WIN-OS/2, MPU401 settings must be added using
         an editor in config.sys after installation.  Use an editor to
         open config.sys. Find the line 
                BASEDEV=MAD16.SYS...

         Add the MPU401 settings at the end of the line. The following lists 
         the available MPU401 options for the MAD16.SYS sound card setup 
         program: 
                 MPU:     Y, N (Enable or Disable MPU401 interface)
                 MPUBASE: 330, 320, 300 (Make sure there is no conflict with
                                         another device on the system)
                 MPUIRQ:  9, 5, 7       (Make sure there is no conflict with 
                                         another device on the system)
        For example, add MPU:Y MPUBASE:330 MPUIRQ:9 at the end of the line to
        enable MPU401 at base address 330 and irq 9.
        Save the changes and shutdown the system. 

        There is no MPU401 support for 928. 

PART 8 - Known Problems
        - WIN-OS/2 support for 924 is not fully implemented. Currently,
          924 WIN-OS/2 support is using a 929 Windows driver. This is 
          just a temporary solution before the 924 Windows driver is
          updated in the next release. This 929 Windows driver can work 
          for 924 if the hardware is set to Windows Sound System Mode 
          which is by default in OS/2. However, if the user DUAL boot 
          to DOS, and run Windows, this 929 Windows driver may not work
          for 924. 

PART 9 - Brief Trouble-Shooting Session

        Problem:  OS/2 cannot detect your sound card and/or CD-ROM
        Solution: Ensure that the BASEDEV=MAD16.SYS... line is located  
                  immediately before the LIBPATH= statement:

        Problem:  No startup sound when starting OS/2
        Solution: Check if System Sound is enabled

        Problem:  Sounds keep repeating
        Solution: This is due to an interrupt conflict on your system. To
                  use a different interrupt selection, open the CONFIG.SYS
                  file for editing and change the SBIRQ option in the
                  MAD16.SYS line to a different interrupt. 

        Problem:  DOS games do not work under OS/2 DOS session
        Solution: Run OS/2 Add Programs located in the System Setup folder
                  to ask OS/2 to add the set of DOS games on your system.
                  This allows OS/2 to setup the DOS session settings best
                  suited for your individual games such as DOOM.

                  If the DOS game still does not run, this may be due to
                  the incompatibility of the game with OS/2. Consult the
                  OS/2 newsgroup - comp.os.os2.games on the internet for
                  FAQs relating to this subject, or the FTP site -
                  hobbes.nmsu.edu.

        Problem:  IDE CD-ROM does not work
        Solution: Ensure that the IDE CD-ROM jumper is closed on your sound
                  card. Consult your sound card manual for details.
        
        Problem:  Compact Disc player does not generate sound.
        Solution: Go to Digital Audio. Under OPTIONS, select Monitor input.
        
        Problem:  The CD ROM device drivers for PANASONIC CR 562/563 and
                  IDE cdrom drives that ship with OS/2 WARP for Windows,
                  do not work. 
        Solution: The drivers that ship with OS/2 WARP "FullPack" fix this 
                  problem.
        
        Problem:  MINSTALL did not add the "BASEDEV=MAD16.SYS.." statement
                  to config.sys.
        Solution: Reduce the length "LIBPATH=.." statement in config.sys to
                  255 characters or less.
