   i. Select Install
   j. When prompted to do so, insert the numbered installation diskettes
      or installation CD-ROM from the OS/2 2.1 product.


3. If you have changed the base I/O port address on your CD-ROM
   host adapter card you must edit your CONFIG.SYS file and add
   modify the /P:nnnn parameter on the BASEDEV=SONY31A.ADD statement in
   your CONFIG.SYS file.  Refer to the "Sony Device Driver Parameters"
   section below.


4. Shut down and restart your system




Installation from the CD-ROM version of OS/2 2.1
------------------------------------------------

1.  Make a copy of the OS/2 2.1 diskette labeled "Diskette 1"

2.  Copy the file SONY31A.ADD from the "Sony CD-ROM Device Driver
    Diskette" to the root directory on the copy of the OS/2 2.1 Diskette 1.

    (Note: If there is not enough room on the copy of OS/2 2.1
     Diskette 1, then delete the file IBM2SCSI.ADD.  If you delete
     IBM2SCSI.ADD, you must also edit the CONFIG.SYS file and delete
     the line BASEDEV=IBM2SCSI.ADD)

3.  Edit the CONFIG.SYS file located on the copy of Diskette 1.
    At the end of the file, add the following statement.

       BASEDEV=SONY31A.ADD  /A:0 /P:nnnn

          where "/P:nnn" is the base I/O port address selected on the
          CD-ROM host interface card.  The default base I/O port address
          for the Sony CDB-334 interface card is 340h, so the statement
          would appear as follows if the card is set to address 340h:


       BASEDEV=SONY31A.ADD  /A:0 /P:0340


    If your CD-ROM drive is attached to an audio card, (i.e. the
    MediaVision ProAudio Spectrum), you must add the /AT parameter
    switch which is described in the "Sony Device Driver Parameters"
    section below.


4.  Begin the installation by inserting the Installation Diskette
    into drive A and restarting the system.  When prompted to insert
    Diskette 1, insert the copy that you modifed.

5.  When the System Configuration screen is displayed during installation,
    the CD-ROM Device Support field will display "None".  Do not modify
    the choice and continue with the installation.

6.  After installation is complete, and you have rebooted your system,
    you will not be able to access your CD-ROM drive.  This is due
    to a defect in the OS/2 2.1 install program.  To access your
    CD-ROM drive, perform the following steps:

    a. Copy the following files from the OS/2 2.1 Diskette 1
       to the drive which OS/2 was installed.
       (Note: the example assume C:, change if different)

       COPY A:OS2CDROM.DMD C:\OS2
       COPY A:CDFS.IFS     C:\OS2

    b. Edit the CONFIG.SYS file on drive which OS/2 was installed
       and add the following statements to the end of the file:
       (Note: the example assume C:, change if different)

       DEVICE=C:\OS2\OS2CDROM.DMD /Q
       IFS=C:\OS2\CDFS.IFS /Q

    c. Shut down and reboot the system


7.  You will need to run Selective Install to copy over some remaining
    system files.

    a. Open the OS/2 System folder on the desktop.
    b. Open the System Setup folder.
    c. Open Selective Install
    d. Select the CD-ROM Device Support check box

       from the OS/2 2.1 product.



Installation from the diskette version of OS/2 2.1
--------------------------------------------------

1. Install the OS/2 2.1 product from the diskettes

2. Go to the section above titled "Installation if OS/2 2.1 is already
   installed on your fixed disk".




---------------------------------
| Sony Device Driver Parameters |
---------------------------------

This section lists the parameters which are supported for the
Sony CD-ROM device driver.  The parameters can be changed by modifying
the BASEDEV=SONY31A.ADD line in config.sys.  It is recommended
to change the transfer mode from it default, software polling transfer,
to software interrupt transfer.  This will help lower the CPU utilization
of CD-ROM applications, enabling better performance for other tasks
while the CD-ROM drive is being accessed.  See the /I parameter below.


For the SONY31A.ADD device driver, the syntax for the line in config.sys
is as follows:

   BASEDEV=SONY31A.ADD [/A:d] [/AT:dd] [/P:nnn] [I:nn] [/V]


   [/A:d]

     Identifies a specific adapter, d.  The adapter is specified as
     a single digit value which is zero based.  (i.e. The first adapter
     is specified as /A:0).


   [/AT:dd]

     Sets the adapter type connected to the CD-ROM drive.

     Supported values are:
               00 = Sony CDB-334 (default)
               08 = Media Vision ProAudio Spectrum-16


   [/P:nnnn]

     Specifies the base I/O port address of the interface card.  The
     port address is specified as a four digit hex value.  Leading
     zeros should be specified.  The value must be the same number as
     the port address selected by the jumper on the host interface card.

     If this parameter is not specified, the default port address for the
     host adapter is used.  For the Sony CDB-334 host interface card,
     the default is 0340.  For the Media Vision ProAudio Spectrum-16 card
     the default is 1F88.

     See the section below titled "Sony CDB-334 Host Adapter
     Jumper Settings".


   [/I:nn]

     Specifies the interrupt request (IRQ) channel number.  This must
     match the value specified on the jumper setting on the interface
     card. If this parameter is not specified, the device driver will use
     software polling transfer.  See the section below titled
     "Sony CDB-334 Host Adapter Jumper Settings".  This parameter
     switch is not supported if the CD-ROM drive is attached to the
     Media Vision ProAudio spectrum.

     Note: Some Sony CDB-334 host adapter cards did not ship with the
           plastic jumper switch to select the IRQ channel on the IRQ
           jumper block.  You must obtain and install the plastic jumper
           switch to enable the IRQ channel.


   [/V]

     The device driver will display the device driver revision level
     and CD-ROM product information at boot time.



Sony CDU31A, 33A Device Driver Parameter Examples
-------------------------------------------------

1.  Sony CDU31A, 33A CD-ROM drive attached to Sony CDB-334 host adapter:

    The Sony CDB-334 host adapter supports base I/O port addresses of
    320h, 330h, 340h or 360h. If the CDB-334 host adapter is set to any
    port address other than the default of 340h, the config.sys statement
    needs to be modified. For example, if the Sony CDB-334 host adapter is
    set to a base I/O port address of 360, the line in config.sys should be:

        BASEDEV=SONY31A.ADD /A:0 /P:0360


    (Note: The Sony Desktop Library model number CDU31A-LL/N includes
           the Sony CDB-334 adapter)


2.  Sony CDU31A, 33A CD-ROM drive attached to Sony CDB-334 host adapter.

    If the Sony CDU31A, 33A is attached to the Sony CDB-334 host adapter at
    base I/O port address of 360h, and the driver is operating in interrupt
    mode at IRQ channel 5, the line in your config.sys should be:

        BASEDEV=SONY31A.ADD /A:0 /P:0360 /I:5


3.  Sony CDU31A, 33A CD-ROM drive attached to Media Vision ProAudio
    Spectrum-16 (PAS-16) host adapter:

    The line in config.sys should appear as follows:

        BASEDEV=SONY31A.ADD /A:0 /AT:08


    (Note: The default port address for the CDU31A, 33A when attached to
           the  PAS-16 card is 1F88.  The Sony Desktop Library model
           numbers CDU31A-LL/L and CDU-7305 include the PAS-16 adapter).


4. Sony CDU31A, 33A CD-ROM drive attached to the Creative Labs Sound
   Blaster Pro, Sound Blaster 16, or Sound Blaster 16 MultiCD
   host adapter:

   The port address specified on the BASEDEV statement in config.sys
   should be 10h above the base I/O port address specified on the adapter
   card.  For example, if the Sound Blaster card is set for a base
   I/O port address of 220h, the line in config.sys should be:

        BASEDEV=SONY31A.ADD /A:0 /P:0230




Sony CDB-334 Host Adapter Jumper Settings
-----------------------------------------

The following tables explain the jumper settings for the CDB-334, the adapter
that ships with model CDU31A-LL/N of the Sony Desktop Library:

                        JP1.1   JP1.2
   Base Addr 0320        On      On
   Base Addr 0340        Off     On
   Base Addr 0330        On      Off
   Base Addr 0360        Off     Off

                        JP4.1   JP4.2   JP4.3   JP4.4
   IRQ 3                 Off     Off     On      Off
   IRQ 4                 Off     On      Off     On
   IRQ 5                 On      Off     Off     Off
   IRQ 6                 Off     On      Off     Off


   (Jumper blocks JP2.x and JP3.x specify DMA channels and SHOULD ALL BE
    OFF, since the OS/2 device driver for the CDU31A, 33A does not use DMA)



--------------------
| Trouble shooting |
--------------------

1. If you are not able to access the CD-ROM drive:


   a.  Add the /V parameter switch to the BASEDEV=SONY31A.ADD statement
       in your CONFIG.SYS file.  For example:

          BASEDEV=SONY31A.ADD /A:0 /P:0340 /V


       After rebooting, the device driver will display the list of
       drives it has identified.   For example:

         IBM OS/2 SONY31A.ADD 1.00
         Copyright (c) Sony Corporation 1992,1993. All Rights Reserved.
         Port:0340  IRQ:Polled
         SONY    CD-ROM CDU31A 1.1I


       If no units were detected, the following message is displayed:

         IBM OS/2 SONY31A.ADD 1.00
         No units detected.


       If no units were detected, see step 1b below.
       If units were detected, see step 1c below.



   b.  Make sure the Base I/O Port Address specified by the /P parameter
       in the config.sys file matches the Base Port Address selected
       with the DIP switch on the interface card.

       The default Base I/O Port Address for the Sony CDB-334 interface card
       is address 0340h.  If you have changed the Base I/O Port Address on
       the card, you must change the /P parameter on the BASEDEV=SONY31A.ADD
       statement in config.sys.

       For example, if you changed the Base I/O Port Address to 0360h, the
       statement in config.sys should be as follows:

           BASEDEV=SONY31A.ADD /A:0 /P:0360


   c.  Make sure all the required files to operate the CD-ROM drive have
       been installed.  You should have the appropriate BASEDEV=
       statement in CONFIG.SYS for your CD-ROM device driver.  You
       should also have the following statements for the CD-ROM system
       files in your config.sys:


          DEVICE=C:\OS2\OS2CDROM.DMD /Q
          IFS=C:\OS2\CDFS.IFS /Q
          DEVICE=C:\OS2\MDOS\VCDROM.SYS
          BASEDEV=SONY31A.ADD /A:0 /P:0340


       If you do not have the above statements in your config.sys, you
       must use the OS/2 2.1 Selective Install to install the CD-ROM
       support files.



2. If the performance of background OS/2 tasks seems slow when the CD-ROM
   drive is accessed.  Or, if the performance of the MMPM/2 Software Motion
   Video clips seems slow or jerky.

   a.  The SONY31A.ADD device driver should be run using the Software
       Interrupt transfer option to enable the best performance in OS/2.
       The IRQ (interrupt request) channel assigned by the jumper on the
       interface card must match the the interrupt channel specified using
       the /I parameter on the BASEDEV=SONY31A.ADD statement in config.sys.
       You must assign an IRQ channel that is not being used by any other
       interface cards on your computer.

       For example, to enable the Software Interrupt transfer option for
       IRQ channel 5 (which is the default IRQ for the card), the
       statement in config.sys should be as follows:

          BASEDEV=SONY31A.ADD  /A:0 /P:0340  /I:5


3.  If the drive letter assigned to the CD-ROM drive under OS/2 is
    different than the drive letter assigned under DOS.

    The CD-ROM drive is assigned the next available drive
    letter after drive letters have been assigned for the
    floppy drives and fixed disk drives.

    The drive letter is also assigned after any installable block
    device drivers which are located in config.sys before the
    DEVICE=C:\OS2\OS2CDROM.DMD statement (i.e. DEVICE=C:\OS2\VDISK.SYS).

    There is currently no mechanism in OS/2 for assigning a specific
    drive letter for the CD-ROM drive.  The drive letter assignment
    under DOS can be controlled by using the /L switch on MSCDEX.EXE
    command line.


----------------------
| Reporting Problems |
----------------------

Defect reports should include the following information:

  CD-ROM Product ID:            Sony 31A
  CD-ROM Firmware Level:
  Device Driver Transfer Mode:  Software Polling or Interrupt driven
  Host CPU type and speed:      (i.e.  25MZ 486)


The CD-ROM product ID and firmware level can be displayed at
boot time by adding the /V switch to the BASEDEV=SONY31A.ADD line
in config.sys.  For example, the following line may be displayed at boot
time after the OS/2 logo screen is displayed:


  Port:0340  IRQ: 0005
  SONY    CD-ROM CDU31A  1.1I


The firmware level in the example above is 1.1I
