MEDIA VISION OS/2 DRIVERS
==============================
May 27, 1993

This file contains important information for OS/2 2.1 users that have
installed Media Vision's OS/2 2.1 MMPM drivers. Along with this file
you should have received a SCSI driver and a Presentation Manager mixer
program.


Audio driver

The audio driver for the Multimedia Presentation Manager subsystem can
be easily installed from the OS/2 distribution disks. That driver is not
included in this release.

The MMPM/2 audio driver is named MVPRODD.SYS. MVPRODD now supports many of
the same command line switches that the DOS device driver MVSOUND.SYS uses.
Here is a list:

/S:X,XXX,X,X SoundBlaster { enable,base addr,DMA,IRQ }
Note: Sound Blaster DMA channel must be 1 on this
driver release.
/N: allows naming of driver /N:PAS161$ (do not change)
/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 can be used to set the IRQ channel
/B:XXX HEX Base board I/O location (DEFAULT: /B:388)
/W:X /W:1 enables warm boot reset (DEFAULT /W:0)
/M:X,XXX,X MPU {enable,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

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 usually will not find the
card. Because of this relocation feature, it's possible for multiple
PAS cards to coexist in the same system.

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 timer. Some new motherboards (system planars) and reportedly
BIOS' from Quadtel 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.

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:1,220,1,5 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 may not be necessary to load MVSOUND.SYS in your DOS & 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. '

Some games, Wolfenstein 3D for example, require the FM synthesizer
chip (the OPL-3) to be in Adlib-compatibility mode. The MVPRODD.SYS
sets the synthesizer chip for enhanced OPL-3 mode. When starting a
DOS session, the synth chip will be in the wrong mode and thus
the game won't recognize the hardware. In cases like this it is
necessary to load MVSOUND.SYS in the DOS box. In the future we will
handle the OPL-3 mode conversion automatically.

The file PROAS.EXE, which is available on the Media Vision BBS and
CompuServe's MULTIVEN forum (GO MEDIAVISION), is a program that
performs the same functions as MVSOUND.SYS but can be run from
autoexec.bat and does not stay resident. It might be useful in
situations where DOS memory is at a premium.

MPU-401 emulation. This requires a PAS 16 with a Rev 'D' MV101 chip.
To check your PAS 16 chip version number, run DEBUG and type
'i FF88' (this assumes card I/O addressing 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






SCSI driver: TMV1SCSI.ADD.
If your Pro AudioSpectrum compatible card has a SCSI interface, Media
Vision has a SCSI driver available to support CD-ROM drives and hard
disks connected to it. The driver is available on our BBS and on
CompuServe (GO MEDIAVISION).

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.

----------------------------------
QUICK INSTALLATION SCSI DRIVER:
----------------------------------

[1] If 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) OS/2 on CD-ROM comes with an two disks (actually 4: 2 3.5"
and two 5.25" disks). The boot or install disk does not
need modification. Disk 1 must be modified to include the
PAS 16 SCSI CD-ROM driver before installation can begin.

(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.

Note on proprietary CD-ROM interface drivers:

Some PAS compatible cards have proprietary, non-SCSI interfaces.
At this writing, the other interfaces available are Sony 535, Sony 31A,
Matsushita and Philips (LMSI). Sony has developed a Sony 31A driver
for the PAS 16 that is currently being beta tested. CompuServe users
can download it from one of the OS2 forums.

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

FREQUENTLY ASKED QUESTIONS
--------------------------------------------------------------------------------

Q: How can I control the mixer functions of the PAS card?

A: Media Vision has developed an application, PROMIX2.EXE, that provides
complete access to the PAS mixing functions. Promix2 is available
on CompuServe and on the Media Vision BBS. Updates to drivers, new
OS/2 programs and third party software will also be available there.

The Promix2 application requires OS2MIXER.DLL to be in the LIBPATH.
The MMOS2\DLL directory is in the libpath.

copy OS2MIXER.DLL to c:\MMOS2\DLL

Copy the Promix2.exe application to the MMOS2 directory.
copy PROMIX2.EXE to c:\MMOS2

Copy the Promix2 help file to the MMOS2 directory.
copy PROMIX2.HLP to c:\MMOS2

You may wish to add an icon to your desktop for launching the Promix2
application. The easiest way to do this is by dragging the Program
template from your templates folder to the desktop. By changing the
settings on the Program and General pages, you'll be able to launch
Promix2.

Promix2's help facility is activated via the F1 keystroke.

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.



Q: Why do volumes change between WinOS2 and OS/2?

A: At present mixer volumes are not globally consistant. When starting a
WinOS2 session, expect the Windows drivers to reset mixer settings.

Q: I have a Pro AudioSpectrum Plus and I can't record or play audio
under OS/2 2.1. What's wrong?

A: In the file MMPM2.INI found in your MMOS2 directory, you'll find a
header like this:
[ibmwavepas1601]
Under this heading you will find the PARMSTRING parameter. Change
the string BPS=16 to BPS=8 and digital audio will work.


Q: Can I use these drivers with OS/2 2.0?

A: OS/2 2.1 is required for audio support. The SCSI driver will work on
both OS/2 2.0 and OS/2 2.1.


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-25J,CDR-36, CDR-37, CDR-72, CDR-73, CDR-74, CDR-82, CDR-83,

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. See the release notes above.


Q: Is Kodak Photo CD supported?

A: Single session, Kodak Photo-CD support is provided for those drives which
support this standard.

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.
