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 Technology Ltd. will not be responsible for any kind of damage, caused directly or indirectly, by using these 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=\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. [HM01231996]
