- ==========================
- What's NEW in this release
- ==========================
-
- - Hardware resources information: use sndtune.exe to check the data is valid
- or not. Especially, when yellow exclamation mark is shown on Sound/Audio device
- in the device manager of system/control panel or the system does not request users
- to provide Windows 95 drivers after the audio card plug-in to PC ISA slot, then
- it is strongly recommended to run sndtune.exe in MS-DOS mode. Either Windows 95
- or DOS/Windows 3.x, if users find something abnormal, please use sndtune.exe
- to reconfigure hardware resources information. This utility program can not be
- run in DOS BOX or MS-DOS prompt of Windows 3.x or Windows 95.

- ===========
- Windows 95
- ===========
-
- 1. DRIVER INSTALLATION
-
- Insert the sound card into your system and power on the computer.
- Windows 95 will detect the sound card and prompt you for the
- driver. Insert the driver diskette into the floppy drive. Windows
- 95 will step through the installation procedure.
-
- Notes:
- - The 82C931 is a Plug-and-Play audio device. It consists of a
- number of logical devices that could be detected and reported by
- Windows 95. These devices are:
- . Gameport Joystick : Joystick interface
- . OPTi Plug-N-Play MPU-401 : MPU-401 interface
- . OPTi Plug-N-Play Sound System : Audio device
- . (optional) Standard IDE/ESDI Hard Disk Controller
-
- - If there is no audio device installed in the system before,
- Windows 95 would prompt user to insert the Windows 95 CD to
- add related audio utilities (like volume control, sound recorder,
- etc.) into your system.
-
-
- 2. RESOURCE RECONFIGURATION
-
- The 82C931 sound device is a fully Plug-N-Play device. Windows 95 can
- detect its available resources and allocate them on-the-fly in the
- installation sequence. In some rare cases, however, resource conflict
- could occur and it is flagged by the yellow exclamation mark shown at the
- Device Manager of the Windows 95.
-
- To resolve the conflict, click on the SYSTEM icon in the Control Panel
- folder and choose Device Manager. From Device Manager, double click
- the "Sound, video and game controller" category and the list of
- installed devices will be displayed. Double click on the device with
- yellow exclamation mark. Choose Resource. Determine the conflict cause
- thru the hints shown in the "Conflicting device lists". Change the
- resource (e.g. I/O address, DMA, IRQ) accordingly. The resource
- setting will be reconfigured.
-
-
- 3. AUDIO CONFIG IN WINDOWS 95's DOS BOX
-
- The audio device's configuration is valid in both Windows 95 and dos box.
- The majority of the audio applications should be running fine in DOS box.
- It was found, however, that certain soundblaster games could launch from
- dos box but failed to produce digital sound or FM music. These games could
- not use the pre-assigned resources but intead expect the popular
- soundblaster settings,i.e., IRQ=5 DMA=1 I/O=220h. As a result, the resource
- mismatch causes the problem. To correct it, make sure the games' setting
- match the assignment shown at Device Manager.
-
-
- To find out what resources are currently assigned to the sound card,
- proceed to open the properties box associated with the "OPTi
- Plug-N-Play Sound System" (Control Panel / Device Manager, under
- "Sound, video and game controller" category) and select the Resource
- tab. The third I/O Address range in the Resources box is used for
- DOS games. The first Direct Memory Access is used for playback. We
- recommend you select the following resources:
- Input/Output Range: 220
- Interrupt request: 5 or 7
- Direct Memory Access: 0 or 1
-
- Choose these resources as appropriate and select OK. The Device
- Manager will dynamically configure the hardware to use the resources
- you've selected. At this point, you may setup your DOS game with the
- settings which you have just chosen.
-
- 4. MPU-401 WAVETABLE CONFIGURATION
-
- if you have a wave table device on board or attached to your
- sound card, you should follow the recommended steps listed above but
- check on the "OPTi Plug-N-Play MPU-401" device settings instead.
- You may need to write down its current settings which might be needed
- for enabling the general MIDI support in some DOS games.
-
- 5. HELPFUL SETTINGS FOR DOS GAMES
-
- To ensure an ideal environment for DOS games, it is recommended that
- you modify the Idle Sensitivity property of the 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 aforementioned property.
-
- When you are playing DOS games in DOS box, you can use hot keys to
- adjust the volume:
- -Alt + Shift + PageUp : Turn up master volume
- -Alt + Shift + PageDown : Turn down master volume
- -Alt + Shift + End : Mute/unmute master volume
-
-
- 6. AUDIO SUPPORT UNDER REAL MODE DOS
-
- In Windows 95, the audio driver is requested and installed automatically
- after the plug-and-play sound card is plugged in. After the driver is
- successfully installed, user would need to run the following to install
- the DOS configuration utility, SNDINIT.EXE, which is USED to initialize
- the sound card for audio application in real mode DOS.
-
- To install this utility, insert the 82C931 Drivers Installation diskette
- in the floppy driver. Click on "Start" and choose "run". Type "a:SETUP.EXE"
- The InstallShield Wizard will guide you through the installation of
- the DOS cofiguration utilities for 82C931.
-
- Note: The resources setting in real mode DOS is independent of the settings
- in Windows 95. So you can configure your sound card DOS
- resource separately. Type SNDINIT.EXE under DOS prompt, the
- DOS resource configuration user interface will be brought up.
- You can select the resources, adjust volume settings, and do sound
- test to see if the resources or the settings are OK.
-
- The command options of SNDINIT.EXE:
-
- /? - Show all the command options
-
- /b - Setup and initialize the sound card in batch mode.
-
- None - When no option is specified, it will activate the
- configuration program. Use this program to
- change the settings of your sound card.
-
-
- ================
- Windows 3.1X/DOS
- ================
-
-
- 1. DRIVER INSTALLATION
-
- Insert the sound card into your system and power on the computer.
- Bring up Windows 3.1, and insert this installation diskette to
- your floppy drive, then go to Program Manager | File | Run,
- select the SETUP.EXE file in the diskette. The InstallShiled Wizard
- will guide you through the installation process and install the
- Windows 3.1X/DOS drivers and utilities.
-
- Your AUDOEXEC.BAT and CONFIG.SYS will be changed for using sound
- card under DOS environment. Please refer to the user's manual
- for more details.
-
- The InstallShiled Wizard will create an "82C931 Application" group
- in Windows 3.1. This consists of audio programs and utilities.
-
-
- 2. RESOURCE RECONFIGURATION
-
- During the driver installation, the installation program interfaces
- with the system BIOS and chooses a set of available resources for audio
- device. These resource settings could be modified later by using the
- configuration program.
-
- The resource settings in Windows 3.1X and DOS are independent of each
- other. The following describes the steps to go through for reconfiguring
- resource setting in Windows 3.1X and in DOS mode:
-
- In Windows 3.1, go to Program Manager | Control Panel | Drivers. Select
- "OPTi 82C931 Audio Driver". Click on Setup, the configuration dialogue box
- will be brought up. Changing the setup would cause the Windows 3.1 to
- restart to make the new resources take effect.
-
- In DOS environment, change to 82C931 directory and run SNDINIT.EXE.
- The DOS configuration interface will be brought up. You can change thge
- hardware settings, perform sound test to see if the setting works out
- properly, or adjust the volume settings.
-
- The command options of SNDINIT.EXE:
-
- /? - Show all the command options
-
- /b - Setup and initialize the sound card in batch mode.
-
- None - When no option is specified, it will activate the
- configuration program. Use this program to
- change the settings of your sound card.None
-
- However, when Intel's CM (Config Manager) is present, you need to
- use ICU to change the sound card resources.
-
-
- 3. AUDIO CONFIG UNDER WINDOWS 3.1X's DOS BOX
-
- The audio device's configuration is valid in both Windows 3.1X and dos box.
- The majority of the audio applications should be running fine in DOS box.
- It was found, however, that certain soundblaster games could launch from
- dos box but failed to produce digital sound or FM music. These games expect
- the popular soundblaster settings, i.e., IRQ=5 DMA=1 I/O=220h. If the config
- in Windows 3.1X is set differently, the resource mismatch would cause the
- problem. If you want to play DOS games in Windows 3.1X' DOS box, please note:
-
- 1) Make sure the game's settings match the ones in Windows 3.1X.
-
- 2) Sometimes, the Setup of the PIF file of a DOS game is crucial.
- To make a game work effectively under Windows, you probably
- have to try a few alternative options through PIF editor.
-
- 3) Not all of the DOS games can run in Windows' DOS BOX. Please refer
- to games' user manual for suggestions. If the issue persists, try to
- launch the game in pure DOS mode.
-
- 4. MPU-401 WAVETABLE CONFIGURATION
-
- If you have a wave table device on board or attached to your sound
- card, please make sure in the configuration dialogue, the MPU401 interface
- is on. You may want to write down its settings for configuring
- the general MIDI setup in the DOS games.
