   This file contains additional information and changes about the
   various software that was not available at printing time.


   Microsoft CD-ROM Extensions (MSCDEX.EXE)
   ========================================

   The above file is needed for operation of CD-ROM drives under the DOS
   environment. This file is only bundled with DOS version 6.x. Therefore, 
   if you are using DOS version 5, please contact your local Microsoft's
   dealers for a copy of MSCDEX.EXE (for DOS version 5 usage).


   CD-ROM Drives Support
   =====================
   
   The sound card supports the following CD-ROM drives:

   Brand            Models
   ---------        -----------------------------
   Panasonic    -   Model CR522/ 523/ 562 and 563
   Mitsumi      -   Model LU005S/ FX001D
   Sony         -   Model CDU31A/ 33A
   Aztech       -   Model CDA268-01A

   The bundled CD-ROM device drivers supports only the following drives:

   Driver           CR-ROM Model
   ---------        -----------------------
   CR56X.SYS    -   Panasonic CR562 & CR563
   SGCDM.SYS    -   Mitsumi LU005S
   SGCD268.SYS  -   Aztech CDA268-01A

   
   Playing Microsoft Windows Sound System (MWSS) RMI Format Music Files
   ====================================================================

   Our Audio drivers support playback of MWSS RMI MIDI files.  However; 
   you are required to change the default setting from <FM Synth (Base)> 
   to <FM Synth (Ext)> in the MIDI-Mapper configuration table prior to 
   the playing of these MIDI files.


   Using Microsoft Windows Sound System (MWSS V2.0)
   ================================================

   If you are using MWSS and intend to activate the Audio Control icon,
   ensure that the recording mode of your current Windows Mixer is set 
   to either Line or Mic, but not MIX (Mixer On).  You can make the change
   by activating the Recording Panel in the Windows Mixer, and click on 
   Line or Mic button.


   Using Digital (.WAV) Audio with DOS 6.x's DoubleSpace*
   ======================================================

   The DoubleSpace utility included with DOS 6.x can cause problems
   if you attempt to play or record "high data rate" (i.e.: stereo/
   44.1kHz/16-bit) digital audio to or from a compressed disk. In
   DOSDAT or WinDAT, the symptom will be a "Disk Could Not Keep Up
   With Digital Audio" error message, or in some cases the program
   may even crash. 

   Therefore, if you anticipate that you will be playing or recording
   a lot of stereo/44.1kHz/16-bit digital audio, you should set up a
   non-compressed drive partition and configure both DOSDAT and WinDAT
   to use this drive as their Work and Temp directories. In both
   programs this is done from the Setup window. 

   For information on setting up a non-compressed partition for your
   hard drive, refer to your DOS 6.x Users Guide. 

   *The same procedure should be followed if you are using Stacker, a
   third-party disk compression utility.


   Notes About Using EMM386.EXE
   ============================

   When running applications with EMM386.EXE installed, the following
   error message may appear:

      "EMM386 DMA buffer is too small"

   You can overcome this problem in two ways:

      - remove the EMM386.EXE entry from the CONFIG.SYS file

      OR

      - add the following parameter to the EMM386.EXE entry in the
        CONFIG.SYS file:

           D=64

           where D specifies how many kilobytes of memory should be
           reserved for buffered Direct Memory Access (DMA).

        An example of this may be:

           C:\WINDOWS\EMM386.EXE D=64

         
                             --- End of File ---
