DESCRIPTION

The following message is received when issuing a command to the CD-ROM 
drive or viewing the drive's returns:

   SYS0015: The system cannot find the specified drive.

No icon for the CD-ROM drive is displayed.

RESOLUTION

1. If the CD-ROM drive is an external drive, make sure it is plugged in
   and turned on.

   Note: An external drive must be turned on before the system is
         started.

2. Make sure all cables connected to the drive are securely fastened.

3. Make sure the drive is a SCSI drive. If it is "daisy-chained" to
   another device, it must have a terminator plug.

4. Edit the CONFIG.SYS file and make sure it has the following
   statements:

   * For the file system and virtual device driver:

        IFS=C:\OS2\CDFS.IFS /Q
        DEVICE=C:\OS2\MDOS\VCDROM.SYS

   * For the SCSI devices:

        BASEDEV=IBM2SCSI.ADD /LED
        BASEDEV=OS2SCSI.DMD

        Note: The ADD file is different, depending on the SCSI adapter
              installed.

   * For the Pro AudioSpectrum:

        DEVICE=D:\MMOS2\MVPRODD.SYS /I11 /D5  /N:PAS161$

   * For the Sound Blaster:

        DEVICE=D:\MMOS2\SBP2D2.SYS 1 1 7 240 4 /N:SBAud1$

        Note: The driver and parameters differ depending on the Sound
              Blaster card installed.

   * For the CD-ROM drive device driver:

     - For SCSI drives:

          DEVICE=C:\OS2\OS2CDROM.DMD /Q
          BASEDEV=TOSHCDS1.FLT

          Note: The FLT file is different depending on which SCSI-1
                drive is installed. SCSI-2 drives do not require the
                FLT file.

     - For Sound Blaster drives:

          DEVICE=C:\OS2\SBPCD2.SYS /P:240

     - Sony 31A uses an ADD file.

     - For the IBM Portable drive:

          BASEDEV=PARCDOS2.ADD

5. Verify that all files specified in the CONFIG.SYS file are present
   on the hard disk. Drivers specified without a path in BASEDEV 
   statements are in the \OS2 directory; those specified without a path
   in DEVICE statements are in the root directory.

6. Check spelling closely. If any file does not exist or is not listed
   in the CONFIG.SYS file, do a Selective Install for OS/2 CD-ROM and
   SCSI support.

7. Rerun any installation instructions that came with the CD-ROM drive
   or controller and adapter cards.

8. Run diagnostic tests of the CD-ROM drive and controller card.
