0. What's NEW in this release
- When Intel's CM (Configure Manager) isn't present, the
program will check whether the sound card has been
configured by the PnP BIOS and if the configuration is
good. It may try to get system resource information from
the PnP BIOS and assign conflict-free resources to the
sound card if it is necessary. In most of the cases the
program detects no error during the configuration, so user
don't need to do the resource selection. However, if your
system doesn't have PnP BIOS, or on your system there is a
legacy device, (that is, the PnP BIOS doesn't know what kind
of resource it may use) whose resource conflicts with the
resource assigned to the sound card, it is necessary that
the user involves in choosing the resource for the sound card.

- The users can always select the resource (Hardware Settings)
they prefer by using /S option when there is no Intel's DOS
CM loaded. But it is suggested that the user use this option
only when the sound card cannot work correctly if running
SNDINIT without /S. That may cause by inacurate information
from the PnP BIOS, that is, the system has some legacy cards
whose resources conflict with the sound card's.

- When Intel's CM (Config Manager) isn't present,
the WSS uses dual-DMA as default (that is, when the codec
supports dual-DMA and the system has two DMA channels
available, the WSS will always use dual-DMA). But by using
/S option and choosing single DMA channel can overrule
this default.

- Windows 3.1x driver gets sound card resource assignment by
reading the sound card PnP resources in stead of reading
the system.ini file. Should the users make any resource
changes, they need to go back to DOS and run SNDINIT (/S).

- SNDINIT program will try the best to make sure all hardware
settings are good for existing DOS games or applications
even if they are not assigned to proper ones by the PNP BIOS
or CM at first. The SNDINIT will give the warning messages
on DOS games/applications compatibility if no way to get the
right hardware resource.

- During the sound card installation (run INSTALL from a floppy
drive), or configuration (run SNDINIT without /B option),
if any warning occurs, the program will display the message
on the screen and save the message in the SOUND16.LOG file.

- Add EXT_OPL3_CONTROL=NO at the system.ini. If the FM OPL3 is
conflicted by other device, the user can set this option to YES.

For V1.04R1:
- Support installation from other media (CD-ROM, network, etc.)
other than floopy diskette.

For V1.04R2:
- When VOLUMEPAGE=NO, don't show the VOLUME button in stead of
graying it in the configuration UI.

This version has been updated from with the following
- Change the version number to support DirectSound.


If you do not have a previous copy of the drivers installed, and
you are installing this Sound Card plus Driver package for the
first time, you may proceed to the FIRST TIME INSTALLATION section.
However, if you are updating your previous installed drivers, you
MUST follow the UPDATE PREVIOUS DRIVERS section below in order to
succesfully install the new drivers.


[Updating "OPTi Plug-N-Play Sound System" Driver]

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 Add New Hardware icon. This will
add/update the OPTi Sound Device and it's associated drivers.

3. 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.

4. 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.

5. 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.

6. Once information from the floppy diskette has been read by
Windows 95, a list of devices available for installation will
be displayed. This list contains driver setup options pertaining
to your Sound Card's capabilities. For example, if your Sound
Card has an IDE CD-ROM interface which you wish to connect your
IDE CD-ROM to, select the appropriate option to enable this
setup. If your Sound Card does not contain any options other
than Audio functions, then just select the first option.

7. Windows 95 will now 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 Yes for the new drivers to
take effect. YOU MUST REBOOT for the changes to take effect!


Install the Sound Card into your system and reboot your machine;
Windows 95 should detect new PnP resource on your Sound Card and
prompt you for the installation files. At this point, insert the
OPTi 82C925 Windows 95 Driver diskette into your floppy drive and
let Windows 95's Device Manager direct you through the installation
of the drivers.

When Device Manager finds a new device but cannot determine/find the
correct driver for the device, it will prompt you for the location
of the drivers associated with the device and will expect that the
drivers are from a floppy diskette.
