UPDATE NOTES

This is an updated version from 4.00.00 and contains the following:

1) Bug fixes found by internal QA.

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 82C929 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 82C929. 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.

++M = Decrease Master Volume
++M = Increase Master Volume
++M = Mute Master Volume

++V = Decrease Voice (Digital Sound) Volume
++V = Increase Voice (Digital Sound) Volume
++V = Mute Voice (Digital Sound) Volume

++F = Decrease FM Music Volume
++F = Increase FM Music Volume
++F = Mute FM Music Volume

MIXER CUSTOMIZATION

Mixer driver customization info should be specified in the SND929P.IN_
file which is located in the installation diskette and is required by
Windows 95 during installation of the drivers.

By default, this file instructs the Mixer driver not to support
any customizations and only the manufacturer's default channel
mappings and controls are supported.

To enable mixer customizations, proceed to the [CUSTOM.AddReg]
section in this file and modify the "Default_Codec_Mapping"
field from "Yes" to "No". This tells the mixer driver not to
use the manufacturer's default mixer mappings but to expect
customized channels mappings and controls instead.

TYPE 1) Channel Mapping Customization

The following are defaults:
..,AUX1_Src_Name,,"CD" // For AUX 1 Channel
..,AUX2_Src_Name,,"Synth" // For AUX 2 Channel
..,DAC_Src_Name,,"Wave" // For LOC and ROC channels

Below are supported only if you have the extended CODEC on board
such as CS4231 or AD1845.

..,LINE_Src_Name,,"Line" // For LINE Channel

..,MIC_Src_Name,,"Mic" // For Microphone Channel
// Supported by AD1845 Only

..,MONOIN_Src_Name,,"Alarm" //

Channel mapping customization allows renaming of a source to
a different name thus changing the original assumed source
mapping of the channel.

TYPE 2) Extra internal controls through existing H/W resource
- for controls using general purpose output bits of CODEC
or MC device.

These internal controls are of the ON/OFF type controlled by a
single toggling bit.

The following are valid:

..,Total_Internal_Controls,1,n // Total number of controls desired,
// maximum is 3.
// Default is assumed to be none.

..,Internal_Control_1_Name,,"SRS-3D" // Name to call this control.
..,Internal_Control_1_OnVal,1,00 or 01 // What is the default ON bit.
..,Internal_Control_1_By,,"XCTL0" or "XCTL1"

// What bits to use for control based on the following
// available on the default H/W.
XCTL0 - OUT 0 bit located at index 10 of CODEC registers
XCTL1 - OUT 1 bit located at index 10 of CODEC registers

..,Internal_Control_2_Name,,""
..,Internal_Control_2_OnVal,1,00 or 01
..,Internal_Control_2_By,,""

.
.

..,Internal_Control_n_Name,,""
..,Internal_Control_n_OnVal,1,00 or 01
..,Internal_Control_n_By,,""

TYPE 3) Extra external controls through external logic
(Requires DLL from third party).

..,Total_External_Controls,1,n // Total number of controls desired,
// maximum is 3.
// Default is assumed to be none.

..,External_Control_1_Name,,"SRS-3D" // Name to call this control.
..,External_Control_1_By,,"XCONT_1.DLL" // The accompanying DLL. Each
// external control has it's own
// unique DLL.

..,External_Control_2_Name,,"" // Name to call this control.
..,External_Control_2_By,,"XCONT_2.DLL"

..,External_Control_3_Name,,"" // Name to call this control.
..,External_Control_3_By,,"XCONT_3.DLL"

Each external control has it's own set of exported functions for
the driver to call. For example, external control 1 will have the
following 3 functions:

XControl_1_Init();
XControl_1_On();
XControl_1_Off();

The accompanying DLL must export these functions exactly as
named above.

** NOTES **

1) Internal and External Controls must be of the ON/OFF control types;
any other types are not supported for now.
