MEDIA VISION OS/2 BETA PROGRAM
==============================
April 7, 1993


Please accept Media Visin's apologies for the problem with COM 2 and the
PAS 16 audio driver on the 3/93 PDK and OS/2 2.1 release. A debug switch
was left on by mistake during the final compile. This release should
correct that error.

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 3/93 PDK or 3/93 OS/2 2.1 BETA
(version 6.498) only. Please do not report bugs found on prior releases
of OS/2. There will not be any support provided now or in the future
for previous versions of OS/2.

RELEASE NOTES:

If you have been using the version of MVPRODD.SYS that comes with the 3/93
PDK and are having problems with:

1) COM2 and/or a serial mouse
this driver should correct the problem. A debug switch was left
enabled by mistake causing strings to be written to the comm port.

2) the /T:1 switch (which stops FM synth hiss on OPTI chipset systems)
this driver fixes a bug in the /T:1 switch handling routine.

3) recording
this driver fixes a bug in recording

New features since the 1/93 beta release:

1) FM synthesis and MIDI output are now supported.

2) Recording is supported.

3) Promix2.exe has had a UI makeover. Promix2 comes up in a reduced-size
mode. Double-click in the client area between any of the controls
and the window will expand to give greater hardware control.

4) MVPRODD.SYS now supports many of the same switches that MVSOUND.SYS
uses. Here is a list:

/S:X,XXX,X SoundBlaster { enable,base addr,IRQ }
/N: allows naming of driver /N:PAS161$
/T:X T:1 = use PAS oscillator for OPL-3 (default /T:0)
/D:X sets the DMA channel
/Q:X sets the IRQ channel
/I:X also sets the IRQ channel
/B:XXX HEX Base board I/O location (DEFAULT: /B:388)
/W:X If /W:1 enables warm boot reset (DEFAULT /W:0)
/M:X,XXX,X MPU {enabled,base addr,IRQ}
/F:X FM Synth disable switch; /F:1 enabled by default
/J:X /J:1 cause Joystick to be enabled, J:0 is default

5) I/O relocation. The PAS Plus and PAS 16 have always been able to
reside at addresses other than the default port addresses: 0x388-0x38b.
This is useful when there are hardware conflicts with another board
that wants to use the same I/O space or when the user wishes to use
multiple PAS cards. If you relocate the I/O addresses, however, be
forewarned that DOS applications and tools will not find the card.

6) Warm Boot Reset. The Warm Boot Reset feature is useful to clear
the tones generated by an Adlib compatible game that has been aborted
with CTRL-ALT-DEL. This feature has been traditionally enabled in
the past. The PAS detects a warm boot reset (CTRL-ALT-DEL) by
decoding writes to the DMA refresh hardware timer. Some new mother
boards and reportedly QuadTel BIOS' use that same timer for something
else, causing the PAS to constantly reset. It's therefore safer to
have this feature default to off. Try adding the switch and if the
card still produces sound, it's not a problem for your system.

7) Sound Blaster Initialization. The PAS 16 has dedicated Sound Blaster
circuitry which operates independently of the high quality digital
audio section. That's why the PAS 16 requires two DMA's and two IRQ's.
The /S switch will enable the SoundBlaster circuitry allowing game
compatibility in a DOS box and also allowing the snblst2.drv and
sbwave.drv drivers to be used in WINOS2.

/S:1,220,5 is the correct setting if using the factory defaults

Notes on MVSOUND.SYS in OS/2 DOS sessions:

The DOS device driver has three main purposes:

1) Initialize PAS 16 hardware, setting mixer volumes

2) Initialize the Sound Blaster circuitry

3) Provide volume control services to DOS apps.

Since the OS/2 driver, MVPRODD.SYS, now provides items 1 and 2 above,
it is not necessary to load MVSOUND.SYS in your DOS or WinOS2 session.
However, if you are using a DOS application that requires MVSOUND.SYS
(e.g. PLAYFILE, Trak Blaster Pro or the PAS utility) you will have
to load it for now. We hope to eliminate the need for MVSOUND.SYS in
the future by use of a VDD.

Warning: MVSOUND.SYS interferes with the PAS SCSI hardware and after
loading MVSOUND.SYS you will lose access to any devices connected to
the PAS SCSI interface. We are investigating the matter and will
provide a new MVSOUND.SYS as soon as it is available.

8) MPU-401 emulation. This requires a PAS 16 with a Rev D chip.
To check your PAS 16 chip version number, run DEBUG and type
'i FF88' (this assumes your card has not been relocated)
If the value is 4, you have a Rev D chip and you can enjoy MPU-401
(UART mode) emulation in DOS session. If you have an older Rev
chip, we hope to emulate MPU-401 hardware with a VDD in the future.

For most systems the following settings will work:
/M:1,330,15


Note on SCSI driver:

The SCSI driver, TMV1SCSI.ADD, has been updated. It fixes some bugs
and is slightly faster (501Kb/sec).

We are developing an improved SCSI driver which will support IRQ-driven
transfers but it's not yet available. This will allow your system to
reclaim CPU time between when a data request is made and when the data
becomes available, boosting overall performance especially with CD-ROM
drives.


Note on proprietary CD-ROM interface drivers:

As of this writing, Media Vision is pursuing development and/or
licensing of OS/2 drivers for the Sony 535, Sony 31A aka SLCD, and
the Philips LMSI drive. We do not yet have beta drivers to offer
for PAS 16's with non-SCSI interfaces.

QUICK INSTALLATION SCSI DRIVER:



[1] If the 3/93 beta release of OS/2 2.1 is already installed, you
can add support for the PAS SCSI interface by


(a) copying tmv1scsi.add to c:\os2

Example:
xcopy tmv1scsi.add c:\os2

(b) adding the following line to \CONFIG.SYS

BASEDEV=TMV1SCSI.ADD


(c) SHUTDOWN AND RESTART

This assumes that the CD-ROM support files have been installed.
(eg. CDROM.IFS)


[2] If installing from CD for the 1st time, here are the basic steps
necessary:

(a) Access the CD-ROM from DOS and run install.bat. This
will create two floppies: the "Boot Disk" and "Installation
Disk #1."

(b) Edit the config.sys file on Installation Disk #1 (the second
disk). Add the line "BASEDEV=TMV1SCSI.ADD".

(c) Copy the TMV1SCSI.ADD file provided with this beta release
onto Installation Disk #1. If the file won't fit, you can
delete fd*.add, assuming you don't also have a Future Domain
SCSI adaptor. If you do, delete aha*.add.

(d) You will now be able to boot the "Boot Disk" and install
OS/2 2.1 from CD. However the installation has finished,
you will not have access to your CD-ROM drive. When OS/2
comes up, edit \CONFIG.SYS and make sure the line
BASEDEV=TMV1SCSI.ADD
has not been removed or REM'd out. If it has, restore the
line, shutdown and restart.


QUICK INSTALLATION AUDIO DRIVER:

MediaVision's ProAudioSpectrum16 Device Driver

***************************
****** BETA ******
***************************
April release for MMPM/2 1.1

To install:

[1] Install MMPM/2 with OS/2 2.1 March Beta
with PAS16 support selected. If this
is already done, skip to next step.

[2] Copy new driver (mvprodd.sys) from this
zipped file image to \MMOS2. This will
overlay the previous driver.

Example:
xcopy mvprodd.sys c:\mmos2

[3] Copy the mixer application (PROMIX2.EXE) to
\MMOS2 and the multimedia mixer library (OS2MIXER.DLL)
to \MMOS2\DLL.

Example:
xcopy os2mixer.dll c:\mmos2\dll
xcopy promix2.exe c:\mmos2

[4] Shut down and reboot system.

[5] Add Promix2.exe to desktop.

versions of the PAS 16 with non-SCSI interfaces. These so-called
proprietary interfaces are one of three types: LMSI (Philips),
Sony 31A, or Sony 535. At present OS/2 drivers are not available
for these proprietary interfaces. Media Vision is endeavoring to
make these drivers available. Please aid us by informing these
companies that you are using OS/2 and require CD-ROM support.

(++) Pro AudioStudio 16's selectable input gainfeature is not supported
on this release.


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: 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 a 3/93 release of OS/2 2.1 (version 6.498) or later to
use this driver release.

Q: How fast is the SCSI interface under OS/2

A: We have measured hard file (hard disk) reads at 504 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. Add tmv1scsi.add
to the second disk and add this line to the config.sys file:
BASEDEV=TMV1SCSI.ADD
Then boot the 1st floppy. The CD-ROM drive will be recognized
allowing you to begin OS/2 installation.

Q: How can I get OS/2 2.1 PDK BETA on CD-ROM?

A: To inquire about the OS/2 2.1 BETA program, 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 MIDI recording
Volume control
Mixer control
PCM Recording
MIDI playback

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: YES! The IBM team has done a superlative job at providing support
for sound hardware using auto-init DMA. You can actually run
TrakBlaster Pro in a DOS session! You will need to load MVSOUND.SYS
for the DOS session. Make sure that your DOS IRQ and DMA settings
match those used by the OS/2 device driver.

If you have trouble with Sound Blaster compatible games, make sure
you add the /S switch (details above). Also, some games (Wolfenstein
3D, for example) check a DOS enviroment variable for IRQ and port address
information.

Add the line
set blaster=a220 d1 i5 T2
to your autoexec.bat file. This assumes you are using the factory
default Sound Blaster IRQ setting of 5.


Q: Will I be able to run the Media Vision Windows drivers in WIN/OS2?

A: Yes. Consider using the Sound Blaster section of the card for
your WinOS2 multimedia audio driver. With such a configuration, you
will be able to use Windows Multimedia utilities and OS/2 multimedia
utilities at the same time. When using the FM, MIDI or PAS digital audio
features in WinOS2, you will not be able to use these features in OS/2
(unless you have multiple PAS cards.)

Q: Can I run the Sound Blaster OS/2 drivers that came with OS/2 on the
PAS 16?

A: No. The Sound Blaster drivers, which were written by Creative Labs
check for Media Vision hardware and fail if they detect a PAS 16,
ThunderBoard or Thunder and Lightning card. We hope to provide an
alternate SB driver in the future.



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