This file contains the following sections:

    1. Environment Variables


1. ENVIRONMENT VARIABLES

   There are three environment variables used to signify information
   of our Sound Blaster cards: SOUND, BLASTER and MIDI.  These
   variables will be setup during your Sound Blaster installation.

   SOUND environment variable

   The SOUND environment variable specifies the directory location of
   Sound Blaster 2.0 drivers and software.  The command for setting
   the SOUND environment variable is as follows:

             SET SOUND=<path>

     Note that there is no space before and after the = (equal) sign.

   BLASTER environment variable

   The BLASTER environment variable specifies the base I/O address,
   interrupt number and DMA channel hardware configuration of the
   Sound Blaster 2.0.  The command for setting the BLASTER environment
   variable is as follows:

             SET BLASTER=A220 I5 D1 T3

     Where:
            A  Specifies the Sound Blaster 2.0 base I/O port
            I  Specifies the interrupt request line
            D  Specifies the DMA channel
            T  Specifies the card type

     Note that there is no space before and after the = (equal) sign,
     but there must be at least one space between two settings.

   MIDI environment variable

   The MIDI environment variable specifies the MIDI file format used
   and where the MIDI data is sent to.  The MIDI data can be sent to
   FM chips or Sound Blaster MIDI port.  Generally, there are three
   MIDI file formats available in the market, General MIDI, Extended
   MIDI and Basic MIDI.  The command for setting the BLASTER
   environment variable is as follows:

             SET MIDI=SYNTH:<1/2> MAP:<G/E/B>

     Where:
            SYNTH:   1  Specifies internal synthesizer (default)
                     2  Specifies Sound Blaster MIDI port

            MAP:     G  Specifies General MIDI file format
                     E  Specifies Extended MIDI file format (default)
                     B  Specifies Basic MIDI file format
