We recommend, but not require, that you use the Minimum Audio Device Driver
located in your API directory when using Educational Software in a 
multi-tasking environment.  This driver will prevent other application to 
access the audio card when the Educational Software is currently running.
To install the driver, follow the following instructions.

INSTALLING THE DEVICE DRIVER

The minimum device driver MINIDD.SYS is in the API directory.  
To install the minimum IBM device driver, the following command has
to be added to your config.sys

     DEVICE=C:\DOS\MINIDD.SYS

Reboot your system after making any changes.


NETWORK INSTALLATION

The INT4DAPI.COM file must be copied to the SYS:PUBLIC sub-
directory on the network.  This will allow all network users
to access the program.

1.  Signon to the network as SYSOP.
2.  Escape to DOS (ALT+ESC).
3.  Enter A:
4.  Enter CD API
5.  Enter Z:
6.  Enter COPY A:INT4DAPI.COM Z:
    The program file will be copied to the SYS:PUBLIC sub-
    directory.
7.  Enter FLAG INT4DAPI.COM SRO
    This flags the file Shareable-Read-Only.
This completes the network installation.

USING INT4DAPI ON THE NETWORK
The INT4DAPI.COM program is a TSR (Terminate and Stay
Resident) program which must be loaded before the start of a
courseware program that utilizes speech.  It must also be
removed from memory when exiting the courseware.  To do
this, the Start Instructions need to be modified for each
piece of courseware that uses speech:

1.  Signon as SYSOP.
2.  Select MODIFY PROGRAM INSTALL OPTIONS.
3.  Find and highlight the program you want to modify by
    using the down and up arrow keys and press F10.
4   Use the tab key to move to the PROGRAM START
    INSTRUCTIONS field.  Insert INT4DAPI /N before the
    normal program start command and insert INT4DAPI /R
    after the normal program start command.
    EXAMPLE:
            ?:INT4DAPI /N^CLSWTR WTR.COM^INT4DAPI /R
5.  Press F10 to save the modifications.

When the program is selected from a user's menu the
following steps will occur:
1.  INT4DAPI will first check for an M-AUDIO CAPTURE and
    PLAYBACK adapter.  If one is present it will load the
    TSR and continue to the next step.  If not the  TSR will
    not be loaded.
2.  CLSWTR WTR.COM will check for an IBM SPEECH adapter. If
    one is present it loads the necessary speech support. If
    either adapter is found then the courseware program is
    loaded.  If neither adapter is found the program will
    return to the user's main menu.
3.  INT4DAPI /R removes the TSR from memory.
