   Additional Parameter for SGCDM.SYS CD-ROM Driver
   ================================================

   If you are using a Mitsumi LU005S CD-ROM drive with the sound card,
   please note that there is an additional parameter (optional) for its
   SGCDM.SYS driver.

   The additional "/X" parameter is be used to load the stock buffers
   (specified with the "/M" parameter) into extended memory.

   For more information on the "/M" parameter, please refer to your
   sound card's manual.

   
   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
