        Sound Blaster AWE32 and Sound Blaster 16 PnP Drivers

        ----------------------------------------------------


Disclaimer

   The Sound Blaster AWE32 and Sound Blaster 16 Drivers and

   related files provided in this package are provided 'as

   is' without any warranties from Creative Technology Ltd,

   expressed or implied with respect to the files.  Creative

   drivers and the related files.


   Proceed with the installation, only if you agree to the

   above terms and conditions.



*WARNING*

---------


   THE INSTALLATION PROGRAM REQUIRES THAT YOU HAVE INSTALLED

   EITHER SOUND BLASTER AWE32 OR SOUND BLASTER 16 WITH

   MMPM/2.


   IF YOU ARE USING SOUND BLASTER PRO OR ANY OTHER SOUND

   CARD, USE 'Selective Install' TO INSTALL SUPPORT FOR

   SOUND BLASTER AWE32 OR SOUND BLASTER 16 AND THEN RUN THIS

   INSTALLATION PROGRAM.


   ALSO NOTE THAT, TO INSTALL THE DRIVERS CORRECTLY, USE THE

   INSTALLATION PROGRAM. SIMPLY COPYING THE DRIVER FILES AND

   UPDATING THE CONFIG.SYS IS NOT ENOUGH. THE INSTALLATION

   PROGRAM UPDATES YOUR CONFIG.SYS AND MMPM2.INI AND CREATES

   OTHER INITIALIZATION FILES AS REQUIRED.



What's New

----------


   New DLL+SYS Architecture

   ------------------------


   The Sound Blaster drivers now come in two parts.  A ring

   3 driver in the form of a DLL(VSD) and the traditional

   ring 0 PDD.  These drivers implement most of the new

   features and interfaces introduced with Warp.


   DART

   ----


   These drivers behave properly with DART enabled applications.

   DART provides a high performance audio interface for games.


   AWE32 SoundFont Support

   -----------------------


   The Sound Blaster AWE32 drivers now include support for

   SoundFont loading.  The control panel application, can be

   used to load SoundFont files into the banks.


   Detection of Various Vibra Chipsets

   -----------------------------------


   These drivers also include support for the latest series of

   Vibra chipsets. Unlike old drivers, the support for different

   Vibra chipsets are built-in and there's no need for a driver

   specific for Vibra.


   Support for Advanced Power Management(APM)

   ------------------------------------------


   These drivers include Advanced Power Management support.

   On systems with APM support, the drivers will suspend and

   resume correctly.


   CSP Codec Support

   -----------------


   CSP support has been added in. You can use the same CSP

   files used in Windows. Copy the CSP files to \MMOS2\DSP

   directory. The drivers look for the CSP files and if the

   required CSP file is not present, it will use the DSP

   files shipped with Warp. The CSP files provide better

   recording/playback quality than the ones shipped with

   Warp.


   Plug n'Play Support

   -------------------


   These drivers include support for Plug n'Play cards.  The drivers

   will detect these cards and automatically initialize them.


   To enable automatic configuration of Plug n'Play cards, omit all

   hardware related parameters in the CONFIG.SYS DEVICE= line.  These

   are /A, /I, /M, /D and /H for base address, IRQ, MPU port address,

   8-bit DMA and 16-bit DMA respectively.


   If any of these parameters are specified, the driver will

   initialize the hardware with the parameter value specified taking

   default values for the parameters omitted.


   Plug n'Play BIOS

   ----------------


   On systems with Plug n'Play BIOS, the driver will not initialize

   the hardware unless otherwise requested.  The BIOS initializes the

   sound board and the driver just reads the settings.


   But again, if any of the hardware parameters are specified in the

   DEVICE= line, the driver will initialize the card with the

   specified parameters.  This feature comes handy when having to

   configure a system with PnP BIOS and with legacy cards that cannot

   be configured.  Such legacy cards might have resource conflicts

   with standard Sound Blaster configuration.  In this case you can

   ask the driver to override the default configuration with the one

   you specified in CONFIG.SYS.


   On some systems, the driver's Plug n'Play BIOS interface in the

   driver causes it to crash during initialization. This is due to

   incompatibility between different PnP BIOS implementations. If

   you get the problem, try /P option with the driver. This tells

   the driver to ingnore the PnP BIOS forcing it not to access the

   PnP BIOS functions even if one is present.


   Co-existence Other Plug n'Play Cards

   ------------------------------------


   The SB driver will initialize *ONLY* Sound Blaster PnP cards.  If

   there are other PnP cards in the system, the driver will not

   initialize them.  Nor will it tamper with other PnP cards that

   have already been initialized by its driver or PnP BIOS.  This

   ensures a certain level of system integrity.



CONFIG.SYS DEVICE= Line Syntax

------------------------------


   The new drivers use a different command line syntax from

   the original Sound Blaster drivers installed with Warp

   MMPM/2.  The new DEVICE= line syntax goes like this,


   DEVICE=<path>\SB16D2.SYS /C:n /D:n /H:n /I:x /A:xxx /B:n /M:xxx /N:SBAUD1$ [/Q] [/EXT]


      /C: - Card Number, this will be set to 1 in most cases

      /D: - 8-bit DMA channel,

            Valid values - 0, 1 & 3

            (Sound Blaster cards that use Vibra chipset do not have 0).

            Default value - 1.

      /H: - 16-bit DMA channel,

            Valid values - 5, 6 & 7

            (Sound Blaster cards that use Vibra chipset do not have 6).

            Default value - 5.

      /I: - IRQ number,

            Valid values - 5, 7, 9, 10 & 11.

            Default IRQ - 5.

      /A: - Base addresss,

            Valid values - 220, 240, 260, 280

            Default value - 220.

      /B: - Buffer size in KB,

            Valid values - 1-24. While any value in this range will work

            fine, to get the best results don't use this option and let

            the driver use the default buffer size.

            Default value - 8KB.

      /M: - MPU port address

            Valid values - 300 & 330

            Default value - 330.

      /N: - driver name, set this to SBAUD1$

      /Q  - quiet mode flag, OPTIONAL

            Setting this option disables initialization messages.

            If not specified the initialization messages are displayed

            during boot-up.

      /EXT - use MPU port instead of internal synth for MIDI, OPTIONAL

            By default the drivers are configured to use the internal

            synthesizer. But if you have a daughterboard attached to

            your Sound Blaster card and you want MIDI playback to

            use the synthesizer in the daughterboard, specify

            this flag.

      /P  - Ignore PnP BIOS if it is present. If PnP BIOS is present,

            the driver usually queries the BIOS for certain PnP port

            addresses. Specifying this option causes the driver not

            to access the BIOS and determine these port addresses

            itself.


   THE NEW DRIVER DOES NOT RECOGNIZE THE OLD POSITIONAL SYNTAX.


   The installation program will make the necessary chages

   to your CONFIG.SYS. But make sure that you have a valid

   existing Sound Blaster AWE32 or Sound Blaster 16 support

   installed in MMPM/2(See *WARNING* above).


   A sample CONFIG.SYS statement looks like this:-


   DEVICE=C:\SBAWE32\SBAWED2.SYS /C:1 /D:1 /H:5 /I:5 /A:220 /B:8 /M:330 /N:SBAUD1$



Using 8-bit DMA Channel for 16-bit DMA

--------------------------------------


   Some systems come without 16-bit DMA support.  In such

   systems, the drivers can be configured to use 8-bit DMA

   channels for 16-bit DMA.  Just set the 16-bit DMA Channel

   parameter(/H:) to use one of the 8-bit DMA channels(0, 1

   or 3).



Reporting Driver Problems & Bugs

--------------------------------


   If you find any problem or bugs in the driver, please do

   report them.  If you have internet access, please post a

   message on the comp.os.os2.multimedia newsgroup.  This is

   the best way to ensure that the bug report reaches the

   driver developer.


   If you do not have internet access, please report the bug

   to Creative Technology/Creative Labs technical support

   and they will inform the developer.
