      ===================================================================


      The OS/2 Warp audio filter driver, CD800X, will enable the audio
      mode of your Apple SCSI CD-ROMs CD-SC, CD-SC Plus and CD-150 (a.k.a.
      SONY CDU-8001, 8002).



      Legal stuff
      -----------

      This program is based on undocumented data structures.
      An error in this base device driver or in software which uses it
      can cause your system to lock up and require rebooting, resulting
      in data loss.
      The user is advised always to make adequate Back Ups of all
      valuable files or data. Because he can have no control over how
      this program is used the author accepts no liability for any damage.

      The author disclaims all warranties as to this software, whether
      express or implied, including without limitation any implied
      warranties of merchantability, fitness for a particular purpose,
      functionality, data integrity or protection, in so far as permitted
      by applicable legislation.

      All trademarks are property of their respective owners and appear for
      identification purposes only.



      Freeware
      --------

      Writing this driver has taken a long time and lots of work (because
      neither Apple nor Sony could/wanted to provide technical information).

      Despite of this, this software is freeware.

      You are encouraged to copy and pass on this program, if the program is
      distributed in its original form (complete, unmodified).



      Installation
      ------------

      It is recommended you have an OS/2 boot disk ready, just in case
      the system locks up during the boot process and you want to remove
      the driver.

      First, ensure that CD-ROM data mode works. If not, select "System
      Setup", "Selective Install" and add a "SCSI II CD-ROM".

      Installation is easy (you don't need to boot from your installation
      disks to install the driver):

      A. Automatic Installation

         Insert your program disk into drive A. Select "System Setup",
         "Device Driver Install" or invoke "DDINSTAL" from the OS/2
         command line.

      B. Manual Installation

        1. Edit your CONFIG.SYS file (using the OS/2 "System Editor"):
            E CONFIG.SYS

        - If present, remove the line "BASEDEV=SONYCDS1.FLT", since neither
          the Apple CD-ROMs are not compatible with this driver.

        - Add the line
            BASEDEV=CD800X.FLT
          (no subdirectory name!)

        2. Copy the file CD800X.FLT to your OS/2 system directory
            COPY CD800X.FLT x:\OS2\BOOT\*.* /V
          where x is your OS/2 boot drive.

      Shutdown and reboot your computer.

      If all goes well and your CD-ROM is powered on, the driver will
      display a message.


      >> If no Apple SCSI CD-ROM is present, the driver won't do anything.
