Introduction
------------
These files comprise the Windows 95 (tm) drivers for the Advanced Gravis
UltraSound family of sound cards based on the GF1 chip: UltraSound Classic,
UltraSound MAX and UltraSound ACE.  The new UltraSound products based on
the AMD InterWave chip, the UltraSound Plug & Play and Plug & Play Pro, come
with Win95 drivers specific to those cards.

This is the first of two versions of the drivers that we will be providing. The 
only thing missing with this version is that you will not be able to run your
UltraSound games in an MS-DOS box. That version is planned for release
at the end of January.

Stay tuned for many more exciting Gravis developments including the new
shipping UltraSound Plug & Play, Plug & Play Pro, Thunderbird, Mac
Firebird (w/new handle), and of course our new 4-player GrIP Game 
System with 8-button GrIP-Pads. As you can see its been a very busy
year, and we would like to thank you for your continuing support.

How to get up and Running
-------------------------

The following list of instructions is an addendum to your existing
UltraSound manuals.

1) You need to have your UltraSound card working in DOS. A good way
   to verify that you have done this successfully is to run MIDIDEMO
   from your UltraSound directory. If you hear music, this means your
   MIDI patches and card are configured correctly.

   You will also need to record what your UltraSound settings are.
   You can do this by typing SET from the DOS prompt. Note the
   variable called ULTRASND. There will be a series of 5 numbers after
   the equal sign. The numbers are in the following order.

   Example:  ULTRASND=220,1,1,11,7

             Baseport Address, DMA1, DMA2, IRQ1, IRQ2

   These settings will be required by Windows 95 for a proper
   installation, so be sure to write these down.

2) Load up Windows 95

3) Click the <START> button in the lower left corner of your main screen.

4) Select <SETTINGS>, then <CONTROL PANEL>.

5) In the Control Panel, select <ADD HARDWARE> to open the Add New
   Hardware Wizard and click <NEXT>.

6) Select <NO> when asked if you want Win95 to search for new hardware,
   and click <NEXT>.

7) Select <Sound, Video and Game Controllers> at the bottom of Hardware
   Types.

8) Click <NEXT>.

9) Click <Have Disk...> and enter the directory where you have unzipped
   the files. eg C:\TEMP or A:\

10) Click <OK>.

11) Select the type of UltraSound card you have. Either Classic, MAX, or ACE.
   Then click on <OK>.

** Windows will complain that there are conflicts. It is telling you this
   because it has found your old UltraSound drivers and cannot remove
   them automatically. If you follow the following steps carefully,
   everything will work out.

12)Click <NEXT> and Windows will copy the drivers to the appropiate
   directory.

13)Click <FINISH> at the next screen. DO NOT start the Conflict Trouble
   Shooter, or you machine may hang.

14)When Windows prompts you to reboot, be sure to answer YES.

   NOTE!! you must do this if you have the UltraSound Windows 3.1 drivers
   currently installed, or the machine will hang.

15)On restart, you may get a message stating "The Ultrasound Driver cannot
   be initialized because of a DRAM failure, or an I/O address conflict.
   Please consult the user's guide for troubleshooting information."  This
   is normal, and is indicating that you must change the resource settings.
   Just press "OK" until the message disappears.


Setting Up The Resources
------------------------

16) After reboot, Click the <START> button in the lower left corner of your
    main screen.

17) Select <SETTINGS>, then <CONTROL PANEL>.

18) Select <SYSTEM> and click on the <DEVICE MANAGER> tab.

19) Click on the <+> next to <SOUND, VIDEO AND GAME CONTROLLERS> and double
    click on <ULTRASOUND xxx> (xxx = Classic, MAX or ACE).

20) Make sure that the <ORIGINAL CONFIGURATION> checkbox is checked.

21) Click on the <RESOURCES> tab.

22) Click on the <SET CONFIGURATION MANUALLY> button.

23) Uncheck the <USE AUTOMATIC SETTINGS> check box. If you leave
    this checked, you might run into conflicts later on.

24) From the List Box labelled <SETTING BASED ON> , choose the configuration
    that shows the <INPUT/OUTPUT RANGE> that corresponds to the base port
    that you recorded eariler (ie: 220).

25) Make sure that the <CONFLICT DEVICE LIST> shows "No Conflicts". If not,
    scroll down the <RESOURCE SETTINGS> list box, double click on <Interrupt
    Request> or the <DIRECT MEMORY ACCESS>, and change the value until there
    are no more conflicts.

26) Click <OK>

27) Click <YES> when asked whether you want to force the configurations.

28) Restart system when asked to.

29) You should now have fully functional UltraSound Windows 95 drivers. Enjoy.


Setting Up The Gameport
-----------------------

1) From the START button choose SETTINGS and then CONTROL PANEL.

2) From the CONTROL PANEL folder, select ADD NEW HARDWARE.

3) Click on the NEXT button.

4) Click on the NO radio button and then the NEXT button.

5) Select SOUND,VIDEO AND GAME CONTROLLERS and click on the NEXT button.

6) Select Microsoft as manufacturer, Gameport Joystick as model. and click
   on the Next button. (Insert the Windows 95 CD-ROM if prompted to do so.)

7) Click NEXT and then FINISH to finish installing the joystick driver.


Hints & Tricks
--------------

1) You do not need to have ULTRASND or ULTRA16 in your AUTOEXEC.BAT
   for these drivers to work. However, the next version of these
   drivers will allow you to make UltraSound games to work in a DOS box.
   With those drivers, you will need these environment variables.

2) When recording from a Mic, Line or CD input, be sure you have set
   your recording source correctly. You can get to this in the
   UltraSound property sheet.

3) Make sure that you are using the same settings in DOS as you are in
   Win 95.  This will avoid any conflicts later when running DOS games
   under Win 95.


Troubleshooting
----------------

1) First thing first. Go back to step 1 of "How to get up and running".
   Make sure you go through each step.

2) If MIDI music is working but you get no digital (WAV) audio, make
   sure you do not have an IRQ or DMA conflict. Using the control
   panel, go to the UltraSound property sheet and adjust the resources
   to ones that are not in conflict.

3) Win 95 may not show all resource conflicts.  If you encounter any
   problems, verify that the same settings work under real DOS (not a
   DOS box in Win 95).

4) If you don't get sound, make sure that you have disabled "Automatic
   Configuration" in the Resources Tab in the device manager for the
   Ultrasound.

5) Also be sure that the "Original Configuration (Current)" check box
   is checked in the Device Usage section of the General Tab in the
   Device Manager.

6) If Windows doesn't boot up for some reason, try booting in safe mode
   and then removing the drivers manually.  After completing this process
   (including rebooting afterward), try re-installing the drivers.

Known Problems
--------------

1) You will not be able to get the UltraSound Mixer and Configuration
   utility working under Windows 95. These were intended only for
   Windows 3.1 and will not work under Windows 95.  You may also
   want to remove the associated icons for these utilities, so that
   you won't run them by accident.

2) These drivers do not come with their own midi map configuration.
   If you are presented a choice between Ultrasound MIDI Synth and MIDI
   Mapper, choose Ultrasound MIDI Synth, or create your own MIDI Map.

3) Note: In the Windows 95 Volume Control, some controls appear on the
   mixer but are not active.  This is normal.  The Volume control applet
   does not hide the controls that are not supported by the card.  As
   well, all of the controls may not be visible when the
   Volume Control applet is run initially.  To enable these controls,
   select OPTIONS/PROPERTIES in the Volume Control applet, and then
   enable the controls you would like to see on the mixer.

4) The option in the Multimedia Options screen entitled "Enable Volume
   Control On TaskBar" is not enabled.  This is because this function is
   for controlling the master volume on the card.  Because there is no
   master volume hardware on the card, this control is disabled.  This is
   normal, and is not a defect in the driver.
