=======================================================================
I.  Overview
=======================================================================

A. WINDOWS 95 SYSTEM REQUIREMENTS:

   * 75MHz Pentium-compatible CPU (200+ MMX CPU recommended for full 
     A3D performance).
   * 16MB DRAM (the Vortex hardware wavetable engine uses a native 
     4MB sample set. Samples are stored on disk and swapped to RAM 
     as required. Typical DRAM footprint is <2MB. 
   * 15MB hard disk space
   * CD-ROM drive
   * Access to Microsoft Windows 95 Installation CD-ROM. 
   * Good-quality speakers or headphones and connecting cables. 
   * Joystick and MIDI keyboard (optional). 


B.  NEW FEATURES:
     This section lists new features incorporated since version 1.00
     of the Vortex drivers.  

(i) Improved A3D performance
  A3D now works on 75MHz CPUs. On faster CPUs, 3D audio realism is 
  greatly enhanced by adding atmospheric absorption effects, and by 
  using sophisticated head-related transfer functions (HRTFs) instead 
  of simple pan and delay models for 3D positional rendering. 

(ii) 64-Voice Wavetable
  This release adds a configurable 32-voice software wavetable engine
  to the 32-voice hardware wavetable engine already available. The
  Vortex Control Panel's MIDI tab selects between:
     * 32 voice pro mode (hardware only)
     * 64 voice gamer mode (32 h/w, 32 speed-optimized voices)
     * 64 voice pro mode (32 h/w, 32 quality-optimized s/w voices.
  Overall voice quality has been improved.

(iii) OPL3 Support
  Both Windows DOS boxes and real-mode DOS now support 4-operator OPL3 
  FM synthesis, in addition to 2-operator OPL2 FM synthesis.

(iv) Simpler installation
  If DirectX5 is not detected on the computer during plug-and-play 
  installation, this release starts DirectX5 setup invisibly. If 
  no problems are detected, installation is automatic and transparent.

(v) Improved MIDI performance
  Vortex now includes its own MIDI driver that replaces the slower 
  default MIDI driver supplied with Windows 95. The Vortex MIDI driver 
  increases the number of games that can use wavetable in a DOS box. 

(vi) Multimedia Application Installation.
  During Vortex driver installation, the driver requests the Windows 
  95 CD-ROM and installs the multimedia applets (Volume Control, Sound 
  Recorder, Media Player, and CD Player) if not already on the system.

(vii) Enhanced Vortex Control Panel.
  The panel organization has been improved. Individual tabs can be 
  hidden and the control panel name can be changed with command-line 
  parameters.  Coding has been restructured to facilitate localization. 

(viii) Improved Mixer.
  The Windows 95 mixer now displays only those devices that are
  available on the system. The mixer also provides a +20dB gain switch 
  setting for condenser/electret microphone support. 

(ix) DirectSound Safe Mode.
  Some DirectX games do not check the number of hardware buffers 
  available before creating a new DirectSound buffer. This can result 
  in no sound. A button on the Vortex Control Panel A3D tab lets you 
  disable DirectSound hardware acceleration. 

(x) Multiple Sound Card Configurations.
  This release lets users install sound cards from multiple vendors
  in their system. If two A3D cards are installed, A3D will be used
  on only one of the cards, selected randomly.

(xi) Automatic AUTOEXEC.BAT and DOSSTART.BAT updating.
  The BLASTER environment variable is updated automatically if the user 
  changes the DOS audio configuration. 

(xii) Improved Installation 
  Our simple installation method requires less user interaction.


C.  WINDOWS 95 DRIVER ISSUES:

(i) Joystick Acceleration - Windows 95 always uses the standard analog 
  gameport by default. Use the Gameport control panel's "Advanced" tab 
  to select the Vortex gameport driver for a boost in speed.
(ii) Multiple sound cards - Some sound cards, such as Ensoniq sound 
  cards, do not correctly report their I/O port utilization to the 
  operating system, which can hang the system. 
(iii) Diamond Monster 3D Graphics card - Download the new drivers from
  Diamond's WWW site to fix noise problems with some games, such as
  "Incoming."
(iv) Hercules Stingray 128 Graphics Card - In the "Display Properties"
  control panel, enable "Allow PCI retries" to fix audio problems. 
(v) IBM 300GL and Sony VAIO USB -  A system hang may occur during  
  Vortex driver installation. Disable USB during installation to fix.


=======================================================================
II.  Quick Start
=======================================================================

   1.  Remove any existing Vortex drivers from previous installations. 
   2.  Install the Vortex hardware.
   3.  Install the Vortex Windows 95 drivers, Microsoft DirectX 5.0, 
       and Vortex demonstration applications.


=======================================================================
III. Software Installation
=======================================================================

A. DRIVER INSTALLATION 

   If you have older drivers in your system, please uninstall them 
   first, as described in Section C below. 
   1.  Power on the system, placing the Install CDROM in the 
       CDROM drive.
   2.  Windows 95 displays "New Hardware Found" message and starts 
       driver installation.
   3.  If Windows prompts you to provide the drivers for the PCI 
       multimedia audio device, choose "Driver Disk Provided by 
       Manufacturer" and select the installation CD-ROM's root ("\") 
       directory.
   4.  You may also be asked to insert the Windows 95 CD-ROM during 
       the install process.
   Note: Some Windows 95 versions (OSR2) do not show this prompt. 
   Instead, they ask whether to search the diskette and CD-ROM drives 
   for the appropriate drivers.

   Installed drivers may include Vortex PCI audio, Vortex wavetable, 
   Vortex mixer, DOS modem port, Vortex gameport interface, Vortex 
   MPU401 interface, and Vortex Sound Blaster emulation. 

   Depending on the version of Windows 95 and the configuration of the 
   system, you may be prompted to provide several file locations. Here
   are the CD-ROMs and directory locations for which you may be 
   prompted:

        Vortex Installation & Driver Disk   \Win95 
        Windows 95 Installation Disk        \Win95 
        Microsoft DirectX 5.0               \Directx
        Vortex Application Setup            \Setup 
        PCI Multifunction Audio Device      \Win95

   You may be asked to reboot several times during installation.
   Reboot when asked.  Additional software will continue to load when 
   Windows restarts, until all components have been installed.

B. DIRECTX 5.0 INSTALLATION

   In most cases, Vortex installs DirectX 5.0 automatically. If you 
   have an unusual system configuration , you may be prompted to 
   install Microsoft DirectX 5.0 after Vortex driver installation. 
   1.  When the DirectX setup panel opens, select "Reinstall 
       DirectX". (Even if you do not have DirectX installed on 
       your machine, the Microsoft DirectX 5.0 setup program still 
       asks if you wish to reinstall).
   2.  You may receive some prompts as to whether to replace specific 
       DirectX files on your computer. If you've previously installed
       an older version of DirectX on your machine, be sure to replace 
       any sound-related DirectX drivers. Video DirectX drivers do not 
       need to be changed.

C.  UNINSTALLING THE DRIVERS

   For driver releases prior to 1.0, please the UNINSTAL.BAT file as
   described in the previously distributed install guide. For driver
   releases 1.0 and later, you can use the following procedure: 
   1. Open to the Windows 95 Device Manager (right-click on "My 
      Computer" and select "Properties").
   2. Open the "Multifunction Adapters" tree and select "Vortex 
      Multifunction PCI Platform"
   3. Press the "Remove" button at the bottom of the Device Manager 
      window pane. 
   4. The drivers are now removed from memory, but are still on the 
      hard disk. To delete the files from the hard disk:
      a.  Open the Windows 95 control panel's "Add/Remove Programs"
          applet.
      b.  To remove the drivers, double-click "Aureal Vortex". A 
          Vortex uninstaller application starts.
      c.  To remove the demo applications, double-click "Aureal 
          Vortex Applications". There is no need to reboot the 
          computer.

=======================================================================
IV. Legacy Audio Compatibility
=======================================================================

A. CHECKING DOS AUDIO CONFIGURATION

    Be sure to configure the games for Sound Blaster Pro or Sound
    Blaster operation. Typical settings are I/O 220h, IRQ5, and DMA3.
    You can verify your system is configured for these settings the 
    resource tab under:

        Control Panel->
           System (Device Manager) ->
              Sound Video, and Game Controllers->

    Available settings:
    I/O range:           220h, 240h, 260h, and 280h
    Interrupt:           5, 7, 9(2), 10
    DMA:                 1, 3
    Joystick port:       201h, 202h, 203h, 204h, 205h, 206h, and 207h.
    MIDI port:           300h, 310h, 320h, and 330h.
    Not all of these settings may be available, depending on the 
    hardware in your computer. 

B. CHANGING THE HARDWARE CONFIGURATION

    Generally, you should not need to change the hardware settings. 
    If you wish to use manual settings, use the following procedure:
    1. Open "Sound Blaster Emulation", "Gameport Interface" or "MPU-
       401 Interface" in the system control panel's "Sound, Video 
       and Game Controllers" tree. 
    2. Clear the "Use Automatic Settings" checkbox.
    3. Select "Basic Configuration 0007" 
       (This lets you select all possible settings on your computer.) 
    4. Move the highlight to select the resource to change.
    5. Press the "Change Setting" Button.
    6. Change settings and press "OK."
 
    When you change DOS audio settings, the drivers automatically 
    update the BLASTER environment variable in your AUTOEXEC.BAT 
    and DOSSTART.BAT configuration files. 

C. DOS BOXES

    Windows DOS boxes are launched from the "MSDOS prompt" in the 
    Windows 95 Start menu. Simply run the game as usual. The game 
    still needs to be configured for the Vortex hardware settings.

    Vortex provides wavetable support in DOS boxes if the game 
    supports General MIDI output. To use wavetable in a DOS box:
    1. Open the Vortex Control Panel MIDI tab. 
    2. Ensure that "Vortex Wavetable Receives DOS Box MIDI" is 
       selected. 
    3. Open the application in a DOS box. Configure the music to use 
       MPU-401 output. 
    The Vortex drivers can also send MIDI to other software wavetable 
    or external MIDI devices installed or attached on your computer. 
 
D. REAL-MODE DOS

    DOS runs in real mode when Windows 95 is not loaded, or when you 
    restart the computer in MSDOS mode from Windows 95. In real mode, 
    make sure the game is configured correctly. Select Sound Blaster 
    or Sound Blaster Pro for both the Music and the Effects device 
    (unlike in DOS box where you can select MIDI for Music). You can 
    select MPU-401 output if you have an external synthesizer connected 
    to the Vortex MIDI port. Make sure the settings for I/O, IRQ, and 
    DMA match the configuration for the Vortex card.

    When you install the Vortex drivers from CD-ROM, Vortex adds some 
    lines to your computer's AUTOEXEC.BAT and DOSSTART.BAT files: 

       PATH=C:/WINDOWS
       ASP4DOS
       SET BLASTER=A240 I5 D3 T4

    ASP4DOS is the Vortex real-mode DOS driver, which is installed in 
    your default Windows directory (C:\WINDOWS by default). If Vortex 
    detects an upper memory manager, it attempts to load ASP4DOS high 
    (see your memory management documentation for more information). 
    Your computer finds ASP4DOS via the PATH statement, which includes 
    a reference to your Windows directory. Your computer then executes 
    the ASP4DOS program during boot. When ASP4DOS.COM is executed, you 
    see text similar to:

VORTEX DOS AUDIO DRIVER (01.1) Copyright (c) 1998, Aureal Semiconductor 
PCI AUDIO PRO enabled at Ports 220-22Fh, Interrupt 5, DMA 3, Joystick 201h.
  
    Some games require the "SET BLASTER" line to find the sound card 
    in your system. In the above example, the BLASTER environment 
    variable is set to I/O port 240h, interrupt 5, and DMA channel 3. 
    The "T4" parameter sets the Type of Sound Blaster to Sound Blaster 
    Pro. 

    When exiting from Windows to MS-DOS, the computer runs DOSSTART.BAT 
    file in the Windows directory, in much the same way as it runs 
    AUTOEXEC.BAT when you boot. Vortex thus places the ASP4DOS.COM 
    command and BLASTER environment variable in the DOSSTART.BAT file. 
    These lines reinstall the Vortex DOS driver and reset the BLASTER 
    environment variable. You do not need to run DOSSTART.BAT in Windows 
    boxes.

E. COMPATIBILITY LIST

    Correct audio operation has been verified on the following games.

    * Games that run in a DOX box are flagged with and asterisk.
   ** Games that run in a DOS box, whereas the original Sound Blaster Pro 
      card requires real-mode DOS, are flagged with two asterisks.

(i) Autodetect
  Some older games do not detect audio hardware automatically. You 
  can still use Vortex legacy audio support for these games by 
  configuring the hardware resources manually:
	* Carmaggedon                   * Fast Attack
        * Castle of Doctor Brain        * Grand Prix II 
	* Command and Conquer           * Hard Ball 4
        * Constructor                   * MDK 
        * Cyberwar                      * Witchaven 2
(ii) Sound Blaster/Sound Blaster Pro Selection
    If both options are available, pick "Sound Blaster Pro" for best 
    quality. The following games work if "Sound Blaster" is selected:
	* Battlechess                   * NHL Hockey 96 
	* Cyberia (use DMA1)            * NHL Hockey 97 
	* Death Gate                    * Ripper 
	* FIFA97                        * Spycraft
