    The Win95 driver will work but the driver has very specific installation instructions. Follow these steps carefully:

    OPTi 82C930 Windows 95 Drivers
    Version 4.00.23
    01/25/96


    UPDATE NOTES

    This is an update of previous release version 4.00.20 and
    contains the following updates:

    1) Enable access to MC registers under all VMs.
    2) Fix Wave Compatibility test failure.
    3) Allow mute settings to be saved for all volume channels.

    INSTALLATION PROCESS

    Please follow these steps below for a proper installation of the
    drivers for Windows 95. It is hereby assumed that you already have
    Windows 95 installed and have properly plugged in your Sound Card.

    1. You should have the latest drivers on a floppy diskette ready
    for installation.

    2. Start Windows 95 and proceed to the Control Panel folder and
    select (double click) the SYSTEM icon.

    3. Select the Device Manager tab to display the list of devices
    currently present on your system.

    4. Check to see if you have previously installed the device.
    Usually, the device name starts with "OPTi .. Sound System."
    If a previous instance of the device does not exist, exit the
    System Properties dialog box and proceed to STEP 6.

    5. If the device has been installed previously, double click on
    the device name to expand the list of sub-devices and select
    "OPTi .. Sound System:..." to remove the set of devices plus
    this parent device. You will not be able to remove child
    devices which are controlled by this parent device unless this
    parent device is removed.

    Check also to see if you have previously installed any Windows
    Sound System or Sound Blaster audio devices or their compatibles,
    and if so, please remove them from the list.

    Once the devices has been removed, you must restart Windows 95
    and proceed to STEP 6.

    6. Select (double click) the Add New Hardware icon located in the
    Control Panel folder to add/update the new device and it's
    associated drivers.

    7. When prompted by Windows 95 for the Auto-Scan option for
    detecting new devices on your System - select NO and proceed
    to the next page.

    8. Windows 95 will display a list of known devices that you
    currently wish to install. Select "Other Devices" eventhough
    the name of the device is included in the list. This forces
    Windows 95 to perform a fresh install for your device. Select
    Next to proceed.

    9. Windows 95 will again display a list containing manufacturer
    names and at which point you should ignore the list and select
    the "Have Disk..." button. This tells Windows 95 to read
    special installation instructions from your diskette to
    correctly install the drivers for your OPTi Sound device.
    You will have to direct Windows 95 to the proper location of
    the floppy diskette.

    10. Once information from the floppy diskette has been read by
    Windows 95, a list of devices available for installation will
    be displayed. This list includes options such as what type
    of CD-ROM that you wish to connect to your Sound Card (meaning
    using the connectors on your Sound Card for your CD-ROM
    interface). Select the correct CD-ROM type combination that
    you desire but make sure that the CD-ROM has already been
    installed and connected to your Sound Card. If you do not wish
    to use your Sound Card for CD-ROM support (as a CD-ROM controller),
    just select the basic option which includes only the Sound/Game
    support.

    11. Select Next and Windows 95 will proceed to install the drivers
    needed for your device and configure your device accordingly.
    Once your device has been successfully configured, Windows 95
    will prompt you to restart your system - select No to skip this
    restart process since you should have your Sound Card properly
    plugged in and installed. If however your Sound Card has not
    been correctly installed, you will have to select Yes to
    restart Windows 95.

    CONNECTING EXTERNAL DEVICES

    Wave Table Device

    To enable driver support for your Wave Table device, you will need
    to reconfigure the "OPTi .. Sound System: Sound/Game.." device
    properties and change the settings to use "Basic Configuration 0."

    RECONFIGURATION OF RESOURCES

    The resources for OPTi 82C930 should be reconfigurable on-the-fly
    unless due to a similar conflicting device present in the system.

    To reconfigure the resources, use the SYSTEM icon located in your
    Control Panel folder and choose Device Manager. From Device Manager,
    double click the "OPTi .. Sound System" option and the list of
    sub-devices will be displayed. Double click on the "OPTi .. Sound
    System: Sound/Game..." device to change the desired resources for
    this parent and it's child devices.

    Once resources have been changed, the driver will be reconfigured
    to operate with the new resources and function as before. You may
    be asked to restart your system and at which point you may select
    No since Windows 95 should have reconfigured your device
    accordingly.

    AUDIO SUPPORT under REAL MODE DOS

    To enable support for DOS Games or multimedia applications under
    a REAL MODE DOS environment, please install the deluxe SNDINIT
    package for 82C930. When prompted during the installation for
    the path to your Windows directory, specify the path if you have
    Windows 3.1 installed on your system (under a seperate directory
    from Windows 95). Select None if you do not have Windows 3.1
    installed.

    AUDIO SUPPORT under WINDOWS 95 DOS BOX

    DOS Game support has been added for this release and is fully
    functional. During the setup for your DOS games, you must ensure that
    the current resources assigned to the sound card matches with the
    current settings requested by your DOS game. To find out what resources
    are currently assigned to the sound card, proceed to open the properties
    box associated with the "OPTi .. Sound System" (Device Manager)
    and select the Resource tab. From the Resources box, you should see the
    current I/O Address range for Input/Output Range Number 1. We recommend
    the 220 Hex address range as opposed to the 240 Hex be selected as most
    games support 220 Hex by default. We also recommend the Interrupt and
    Direct Memory Access settings of 7 and 1 respectively. Reconfigure these
    resources as appropriate and select OK for Device Manager to dynamically
    change and update your current resources and configure the hardware.
    At this point, you may setup your DOS game with the settings which you
    have just configured.

    Also, if you have a Wave Table Device on board or attached to your
    sound card, you should also follow the recommended steps above but
    this time check on the "OPTi .. MPU-401" device settings
    instead. You will need it's current settings if you wish to enable
    General MIDI support in your DOS games.

    To ensure an ideal environment for DOS games, it is recommended that
    you modify the Idle Sensitivity property of your DOS Game environment
    to High. To do this, press the ALT+ENTER keys to change to a DOS Box
    Window (if not already in a Windowed session) and click on the top left
    hand corner of the DOS Box Window. A drop down menu will appear and
    at which point you should select Properties. Select the Misc tab and
    proceed to modify the above mentioned property.

    HOT-KEY SUPPORT under WINDOWS 95 DOS BOX

    The following are the Hot-Keys and their associated channel controls.

    <CNTRL>+<ALT>+M = Decrease Master Volume
    <SHIFT>+<ALT>+M = Increase Master Volume
    <CNTRL>+<SHIFT>+M = Mute Master Volume

    <CNTRL>+<ALT>+V = Decrease Voice (Digital Sound) Volume
    <SHIFT>+<ALT>+V = Increase Voice (Digital Sound) Volume
    <CNTRL>+<SHIFT>+V = Mute Voice (Digital Sound) Volume

    <CNTRL>+<ALT>+F = Decrease FM Music Volume
    <SHIFT>+<ALT>+F = Increase FM Music Volume
    <CNTRL>+<SHIFT>+F = Mute FM Music Volume

    <CNTRL>+<ALT>+C = Decrease CD Audio Volume
    <SHIFT>+<ALT>+C = Increase CD Audio Volume
    <CNTRL>+<SHIFT>+C = Mute CD Audio Volume

    FULL-DUPLEX DUAL-DMA SUPPORT

    To enable Dual-DMA channel operation for simultaneous playback and
    recording, please ensure the following:

    1. The DMA resource settings under Device Manager must be different
    and paired as follows:

    Playback DMA: 0 1 3
    Recording DMA: 1 0 0

    2. The frequency format (eg. 11KHz, 22KHz..) must be the same during
    simultaneous playback and recording.

    I just put one of those in two days ago, by coincidence. I must have some sort of updated driver, cause i didn't need to do anything except let windows find it, and point it towards the driver. If you post an email I will send you the driver I used.
