Installation Notes for UltraSound Extreme Sound Card

1.0.0 Installation on Windows 95

If you have AutoPlay enabled, simply insert the CD-ROM into your CD-ROM drive
and the Setup program will start automatically.  Otherwise, simply RUN the
SETUP95.EXE located in the D:\WIN95\INSTALL\ directory of the CD-ROM (where D
is your CD-ROM drive).

Follow the instructions given by the installer and reboot your system when
asked to do so. 

1.1.0 Installing Games and Utilities for Extreme

After the card is properly set up, various games and utilities can be
installed by running GAMES.EXE located in the D:\WIN95\GAMES\ directory
of the CD-ROM (where D is your CD-ROM drive). If you have AutoPlay enabled,
simply eject the CD-ROM and re-insert it into your machine again.

1.2.0 Existing Gameport

If you have a gameport installed on your system, REMOVE it before you install
the Windows 95 drivers.  Otherwise the UltraSound Extreme device will indicate
a failure under Device Manager within the System Property page.

The gameport can be removed by first opening up the SYSTEM PROPERTIES PAGE and
then clicking on the DEVICE MANAGER tab and then selecting GAMEPORT JOYSTICK
(under the "Sound, Video and Game Controllers" section) and then clicking on
the REMOVE button.

2.0.0 Installation on DOS/Win31

2.1.0 Installing Over Existing UltraSound Software

If you experience problems after installing this new set of software,
simply delete your UltraSound directory and re-install.

2.2.0 Temporary Directories

After installation, a temporary directory, ADMALTOI or ISFYZQVO.TWJ,
may be left undeleted on some systems. These directories can be safely

2.3.0 Setting up for Windows

The UltraSound uses buffers to store sound information when playing and
recording digital data.  The size of these buffers can affect the
performance of the UltraSound in certain applications.  The buffer size can
be changed in Windows by choosing the UltraSound Configuration icon for the
Gravis program group under Windows.  You can then type in a new value for
"buf size" in the sections for DMA Channel A and DMA Channel B.  The default
buffer size of 4096 bytes generally gives the best results when recording and
playing back data.  The largest buffer size is 8192 bytes.  Applications such
as voice recognition can work better with a smaller buffer.  If such an
application is not working as expected, try using a smaller buffer size.  The
minimum size is 512.

2.4.0 Setting up ESS Windows Software

The install program creates a Windows program group containing the two setup
programs for ESS audio applications.  Run `Setup for ESS Audio Apps' before
`Setup for ESS Audio Rack'.  Note that the ESS drivers are installed by the
UltraSound Setup program.  This is done to configure the ESS and UltraSound
audio engines to work together optimally.

After installing the ESS software, you should restart Windows before using it.

Note that the external MIDI port will not work until you install the ESS

2.5.0 Changing MIDI port address

Run ESSCFG.EXE (a text mode program) to change or view this address.  This is
not normally necessary because the Setup program configures it for you.

2.6.0 Midimap.cfg file

The MIDIMAP.CFG file in the WINDOWS\SYSTEM directory is set to read only.
When you first run MidiMapper, Windows displays a notice stating MIDIMAP.CFG
is set to read only, and the current configuration cannot be changed in

To remove the read-only attribute for midimap.cfg, run File Manager.  Move to
your WINDOWS\SYSTEM directory and find midimap.cfg.  Select it.  Choose
Properties from the File menu.  Click on the Read Only check box to remove the
read only attribute.  Close the dialogs and exit File Manager.  Now when you
start MidiMapper, you will be able to select other configurations or create
your own.

The MIDIMAP.CFG provided contains setups to send MIDI data to the UltraSound
MIDI engine (default), the ESS FM MIDI engine, and the external MPU401 MIDI
port (accessable through the gameport connector).  You can also create your
own custom MIDI configurations.  Refer to the Windows documentation for more
