1. QUICKCD
   
   The QuickCD application plays audio CDs in DOS and Windows. The
   mixer button in the Windows QuickCD will not be supported if you
   do not have a Sound Blaster Pro or Sound Blaster 16.
  

2. COMMON QUESTIONS AND ANSWERS

   The Common Questions and Answers (CQA) .COM and .TXT files contains
   some common questions that are asked and the answers to them. You
   can run it by typing "CQA" and pressing [ENTER] in the \SBCD
   directory after the installation.


3. OS/2 CD-ROM DRIVER

   An OS/2 compatible CD-ROM device driver is included on this disk.
   The following steps provide instructions on how to install the driver
   with OS/2 versions 2.0 and 2.1.

   The file SBCD2.ADD can be used with OS/2 systems which support layered
   CD-ROM device management structure.  This structure is supported in
   OS/2 2.1.  Users of OS/2 2.0 can use the OS2CDR package which
   contains the OS2CDROM.DMD file for OS/2 2.0.  The OS2CDR.ZIP file is
   available on Compuserve, forum IBMOS2.


   INSTALLATION OF CD-ROM DRIVER IF OS/2 2.x IS ALREADY INSTALLED
   --------------------------------------------------------------

   OS/2 2.0 users--refer to the document provided in the OS2CDR package first.

   1. If you have previously installed OS/2, check whether you have
      the following lines in your OS/2 CONFIG.SYS.  If you do, delete them
      (or REM them out) from your OS/2 CONFIG.SYS file.

           DEVICE=C:\OS2\CDFS.IFS /Q
           DEVICE=C:\OS2\CDROM.SYS /Q /N:4

   2. The following lines must be in your OS/2 CONFIG.SYS file for
      the CD-ROM to work.  The "IFS=..." line may already be in your
      OS/2 CONFIG.SYS file.  If it is, group it with the lines below;
      otherwise, add it.  WARNING: Place these lines near the bottom of
      your OS/2 CONFIG.SYS file--there may be problems if you place them
      near the top!
           
           REM ---- NEXT 4 LINES ARE FOR OS/2 CD-ROM SUPPORT -----
           BASEDEV=OS2CDROM.DMD          (DO NOT SPECIFY A PATH !)
           BASEDEV=SBCD2.ADD /P:250      (DO NOT SPECIFY A PATH !)
           IFS=C:\OS2\CDFS.IFS /Q
           DEVICE=C:\OS2\MDOS\VCDROM.SYS

      NOTE: The /P:250 specifies the I/O base address used for CD-ROM
	    interface card.  Change this value accordingly if your setting 
	    is different.

   3. Copy the OS2CDROM.DMD file (on OS/2 2.1 "Diskette 1") to C:\OS2.

   4. Copy the SBCD2.ADD file from this disk to the C:\OS2 directory.

   5. Reboot the system.


   INSTALLATION OF OS/2 2.1 AND CD-ROM DRIVER
   ------------------------------------------

   1. Make duplicate copies of the IBM OS/2 2.1 diskettes--
      "Installation Diskette" and "Diskette 1"--that come with OS/2 2.1.
      Only make changes to the duplicate diskettes.  Keep the original
      diskettes in their original condition!

   2. Copy the SBCD2.ADD file from this disk onto the duplicate OS/2 2.1 
      "Diskette 1".

   3. Add in the following line to the CONFIG.SYS file on the
      duplicate "Diskette 1".

           BASEDEV=SBCD2.ADD /P:250

      NOTE: The /P:250 specifies the I/O base address used for CD-ROM
	    interface card.  Change this value accordingly if your setting 
	    is different.

   4. Reboot the system with the disk "Installation Diskette" and
      follow the installation instructions.

   5. After the installation is completed, edit your OS/2 CONFIG.SYS file
      to include the following lines.  Make sure they appear near the end
      of the file.  You will have to manually add two of the following:

           BASEDEV=OS2CDROM.DMD          (DO NOT SPECIFY A PATH !)
           BASEDEV=SBCD2.ADD /P:250      (DO NOT SPECIFY A PATH !)
           IFS=C:\OS2\CDFS.IFS /Q
           DEVICE=C:\OS2\MDOS\VCDROM.SYS

      NOTE: The /P:250 specifies the I/O base address used for CD-ROM
	    interface card.  Change this value accordingly if your setting 
	    is different.

   6. Reboot the system.

   
  DESCRIPTION OF SBCD2.ADD SWITCHES
   ---------------------------------

   /P:xxx

   This switch specifies the port address (in hex) of CD-ROM interface card
   used.  The options of xxx are 250 and 260.  Default setting for xxx is 
   250 

   Example:

              BASEDEV=SBCD2.ADD /P:250


   The following switches are optional:

   /D:a or /D:x [,y] [,z] [,w]

   This switch applies only to CR-563 drives.  It specifies the drives 
   to be run at double transfer speed (300KB/s).  The option /D:a 
   specifies 'all' daisy-chained drives.  You can specify individual 
   drives using the ID number of the drive(s) you want to run at double speed.

   Example 1:

              BASEDEV=SBCD2.ADD /D:a

   Example 2:

              BASEDEV=SBCD2.ADD /D:1,3


   /N:a or /N:x [,y] [,z] [,w]

   This switch applies only to CR-563 drives.  It specifies the drives
   to be run at normal transfer speed (150KB/s).  The option /N:a specifies 
   'all' daisy-chained drives.  You can specify individual drives using
   the ID number of drive(s) that you want to run at normal speed.

   Example 1:

              BASEDEV=SBCD2.ADD /N:a

   Example 2:

              BASEDEV=SBCD2.ADD /N:0,2


   NOTE : The default is double transfer speed whenever it is possible.
          If the same drive has been set more than once, the last
          setting will take effect.


   /T:1 or /T:2

   This switch specifies the type of card being used; 1 for standard
   sound card and 2 for CD-ROM interface card.
