MEDIA VISION OS/2 BETA PROGRAM ============================== January 14, 1993 Media Vision is providing these OS/2 drivers for BETA testing purposes only. Use of these drivers requires advanced technical knowledge of OS/2 and its architecture. IMPORTANT: ---------- ** Media Vision's Technical Support department does not ** ** support BETA drivers. All questions and support ** ** issues must be addressed to CompuServe ID 75300,2772 ** ** in the MULTIVEN CompuServe forum. Please do not ** ** call Media Vision's Technical Support department. ** This beta release is intended for use with OS/2 2.1 BETA only. Please do not report bugs found on prior releases of OS/2. --------------------------------------------------------------------------------- --------------------------------------------------------------------------------- QUICK INSTALLATION: 1) FILE OPERATIONS: copy tmv1scsi.add c:\os2 copy mvprodd.s?? c:\os2 copy os2mixer.dll c:\os2\dll copy promix2.exe c:\os2 2) ADD TO CONFIG.SYS: BASEDEV=TMV1SCSI.ADD DEVICE=c:\os2\mvprodd.sys /I:15 /D:5 [Note: /I:XX sets the IRQ, /D:X set the DMA] 3) ADD TO DESKTOP: PROMIX2.EXE 4) SHUTDOWN AND RESTART --------------------------------------------------------------------------------- --------------------------------------------------------------------------------- BETA RELEASE FILES: TMV1SCSI ADD 23041 9-15-92 3:59p OS/2 SCSI device driver TMV1 DDP 355 1-12-93 4:46p Device driver install script TMV1SCSI DDP 362 12-16-92 11:12a Device driver install script MVPRODD SYS 29327 1-14-93 4:37p MMPM audio device driver MVPRODD SYM 7236 1-14-93 4:37p symbol file for above driver OS2MIXER DLL 48399 1-14-93 5:24p Multimedia Mixer Library PROMIX2 EXE 48651 1-14-93 5:26p PM mixer application README TXT This file -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Q: What Media Vision Products are supported? A: SCSI support Audio support -------------- -------------- Pro AudioSpectrum Pro AudioSpectrum Pro AudioSpectrum 16 (SCSI versions) Pro AudioSpectrum 16 CDPC XL CDPC CDPC XL These products have not been tested for this beta release: Pro AudioSpectrum Plus (SCSI versions) Pro AudioSpectrum Plus Q: Can I play CD audio? A: The SCSI driver will support CD (Redbook) audio playback when used in conjunction with IBM's MMPM/2 system software. It will also support most SCSI hard disks. Q: What CD-ROM drives are supported? A: CD-ROM Drive Support List ------------------------- Hitachi CDR-1650S, CDR-1750S, CDR-3650, CDR-3750 IBM CD-ROM I, CD-ROM II NEC CDR-36, CDR-37, CDR-72, CDR-73, CDR-74, CDR-82, CDR-83, CDR-84 Panasonic CR-501, LK-MC501S Sony CDU-541, CDU-561, CDU-6111, CDU-6211, CDU-7211 Texel DM-3021, DM-3024, DM-5021, DM-5024 Toshiba XM-3201, XM-3301 The NEC 25j (aka the MV-8) which ships with the Fusion CD product is currently being tested by IBM. Our test show it to work fine. Support is provided for both data and audio on all models. If you have a "CDPC", "Fusion CD 16" or "Media Vision Multimedia Upgrade Kit " you should have a CD-ROM drive with a Sony interface. The Sony interface is not yet supported. Sony is reported to be developing a driver for this interface. Q: Is Kodak Photo CD supported? A: Single session, Kodak Photo-CD support is provided for those drives which support this standard. Q: Can I use these drivers with my version of OS/2? A: You must have OS/2 2.1 BETA to participate in this BETA program. Q: How fast is the SCSI interface under OS/2 A: We have measured hard file (hard disk) reads at 498 Kb/sec and CD-ROM (NEC 83j) reads at 238 Kb/sec. Q: If I have trouble, what should I do? A: Media Vision's tech support department will not be able to assist in any OS/2 installation or operation issues at this time. Support for these drivers can be obtained by sending mail to CompuServe ID 75300,2772 or leaving a message in the Media Vision section of the MULTIVEN forum addressed to the same user ID. At the CompuServe prompt you can type GO MEDIAVISION to be sent to the Media Vision (MULTIVEN forum. Q: How can I install OS/2 2.1 BETA from CD-ROM if my CD-ROM drivers aren't loaded? A: Use the DOS install.bat file found in the root directory of the OS/2 2.1 BETA CD to create two installation disks. Remove all references to .ADD files for SCSI adapters which are not installed in your system. These include the files aha*.add and fd*.add. Then boot the floppies and the CD-ROM drive will be recognized allowing you to begin OS/2 installation. Q: How can I get OS/2 2.1 BETA on CD-ROM? A: To inquire about getting an OS/2 2.1 BETA CD, contact IBM at 1-800-3IBMOS2. Q: What sound support is enabled? A: This table show functions that are currently enabled and disabled: ENABLED FUNCTIONS DISABLED FUNCTIONS ------------------ ------------------ PCM Playback PCM Recording Volume control MIDI playback Mixer control MIDI recording Q: Which .WAV files can I play. A: You should be able to play any PCM (uncompressed) .WAV file with sampling rates between 4 and 48 KHz, mono or stereo, and 8 or 16 bits. Q: How can I change my card's DMA and IRQ settings? A: The PAS Plus, PAS 16 and CDPC all have software configuration settings. The 'device=' line in config.sys can be used to specify different IRQ and DMA settings. DEVICE=c:\os2\mvprodd.sys /I:7 /D:3 The /I parameter is used to set the IRQ. The /D parameter is used to set the DMA. Valid IRQ settings are: 2,3,4,5,6,7,10,11,12,14,15 Valid DMA settings are: 1,2,3,5,6,7 DMA channels 5,6,7 use 16-bit data transfers and are preferable choices. Q: Will I be able to run my DOS games and applications? A: The OS/2 2.1 BETA release, as well as prior releases of OS/2, do not support auto-initialized DMA. This will cause the DOS applications playfile.exe, recfile.exe and TrackBlaster Pro to fail. IBM has been made aware of the bug and is working on a fix. Adlib compatible games will work in a DOS/OS2 session. Sound Blaster compatible games may work in a DOS/OS2 session. We have no test results at this time. Q: Will I be able to run the Media Vision Windows drivers in WIN/OS2? A: Since auto-initialized DMA mode is not supported in OS/2 2.1 BETA, digital audio will not work in WIN/OS2. This should be fixed in the final OS/2 2.1 release. --------------------------------------------------------------------------------- --------------------------------------------------------------------------------- Known Problems: Loading MVSOUND.SYS in a DOS box will disable the SCSI driver. Pro Mixer's PLAY/RECORD buttons don't react when clicked. Pro Mixer's circular sliders don't update when other applications modify a volume setting. When a wave file is stopped, the time position is reset to zero. Toshiba model 3301 CD-ROM drive volume control doesn't work. AUDIOIF.DLL in \MMOS2\DLL may cause some problems with multiple opens. IBM may allow us to distribute a patched version in the coming days or weeks.
