Media Vision Jazz-16 Device Driver for OS/2 2.1
Information on how to install Media Vision
Jazz-16 OS/2 device driver on OS/2 2.1.
Using JAZZ16 CD-ROM Interface
You should have support for the CD-ROM already installed. To install CD-ROM
support use Selective Install to install the appropriate CD-ROM device driver.
A Statement like the one below, should be in your system configuration
file (CONFIG.SYS), found on your OS/2 Boot drive. Additional information
can be found in the OS/2 System Help under BASEDEV.
Example for the Panasonic 562,563:
BASEDEV=SBCD2.ADD /P:340 /NS
(/P: is the I/O Port Address, 340 is the address of the CD-ROM device
controller on the Jazz-16 audio card.)
System Requirement
Before you install Jazz-16 for OS/2 audio support, check to see if you
have the October 1993 version of the MMPM/2 CSD, or later level, installed
on your system (CSD stands for Corrective Service Diskette and is IBM's
inter-rim release for bug fixes). Use the SYSLEVEL command to determine
which level of MMPM/2 you have installed. The "Current CSD Level" field
displays one of the following values:
UN0000 - The version of MMPM/2 as shipped with OS/2 2.1. An update
is required.
UN49407 - The October 1993 CSD version of MMPM/2.
No update is required.
This is the same version indicated for the OS/2 2.1 service
refresh of February 1994.
The MMPM/2 CSD should be installed on top of OS/2 2.1.
You can obtain this CSD
free from Compuserve or from the IBM OS/2 BBS.
CompuServe:
OS/2 Support Forum:
Library 17: mmpmcs.dsk
IBMM BBS:
mmoscsd.dsk
Once the Jazz-16 driver is installed, the appropriate DEVICE = statements
for JAZZDD.SYS are included in your CONFIG.SYS file. Also, the audio device
properties are updated in C:\MMOS2\MMPM2.INI. Before installing the Jazz-16
driver, please refer to the following procedure.
If you previously installed PAS16 on your system and are now switching
to Jazz-16, the following installation procedure will NOT delete
the audio device property sections for PAS16 in MMPM2.INI. Instead, the
Jazz-16 audio device property sections are APPENDED. The following changes
are REQUIRED for the MMPM2.INI file:
o In section [drivers],
CHANGE:
Waveaudio=IBMWAVEPAS1601,IBMWaveJazz1601
Sequencer=IBMSEQPAS1601,IBMSeqJazz1601
Ampmix=IBMAMPMIXPAS1601,IBMAmpMixJazz1601
TO:
Waveaudio=IBMWaveJazz1601
Sequencer=IBMSeqJazz1601
Ampmix=IBMAmpMixJazz1601
o DELETE the following sections:
[ibmwavepas1601]
[ibmseqpas1601]
[ibmampmixpas1601]
If you do not make the required changes, the following error messages are
displayed when opening:
o Digital Audio Player:
"The desired action is not supported by the current device, or the
desired hardware is defective".
o MIDI Player:
"Unable to open device 'MIDI'. There is no device driver for the
associated device".
If your Jazz-16 adapter does not function properly after installation, then
the correct version of MMPM/2 was not installed and the appropriate device
statements were not added to your CONFIG.SYS file.
Media Vision Jazz-16 Installation Procedure
To install device support, insert the Jazz-16 Device Driver diskette into the
drive you wish to install from (for example, drive A: or B:). Start the
multimedia installation program, located in the Multimedia folder on the OS/2
desktop and then select the drive that contains the Jazz-16 Device Driver
diskette.
The OS/2 Audio drivers are located in the \OS2 directory on the diskette.
Select the \OS2 directory to continue the installation.
The Jazz-16 Audio Adaptor icon will appear in the Features window, with
version
and size information. Click on the icon to select it and then click on the
Install button to continue installing.
The multimedia installation program adds two Jazz-16 device driver
statements to your CONFIG.SYS file. These statements are displayed as
follows:
DEVICE=C:\MMOS2\JAZZDD.SYS /I:5 /D:1 /E:7 /T:330 /Q:10 /P:240 /N:JAZZ1$
DEVICE=C:\MMOS2\AUDIOVDD.SYS JAZZ1$
Jazz-16 OS/2 DEVICE DRIVER PARAMETERS:

| | |
/I: | Wave audio IRQ | 3, 5, 7, 10, 15 | 5

/D: | 8-bit DMA channel | 1, 3 | 1
| | |
/E: (/H:) | 16-BIT DMA channel | 1, 3, 5, 7 | 5
| | |
/T: | MPU-401 I/O base address | 300, 310, 320, 330 | 330
| | |
/Q: | MPU-401 IRQ | 3, 5, 7, 10, 15 | 10
| | |
/P: | Audio I/O base address | 210, 220, 230, 240, 250, 260 | 220
| | |
/N:JAZZ1$ | Name of PDD | JAZZ1$ (supplied by install) |
-------------------------------------------------------------------------------
NOTE: If you have installed the ISA Token-Ring 16/4 II Adapter you
can use the following values (example) for the JAZZ setup:
Base Address = 260
MPU Address = 330
MPU-401 IRQ = 10
IRQ = 5
DMA 8-bit = 1
DMA 16-bit = 5
be sure you have not set IRQ=5 on the Token-Ring Adapter.
MIDI
MIDI Playback on OS/2 requires Jazz-16 jumper J9 be "open" thus enabling
the MPU-401 compatibility hardware on the Jazz-16.
Using Audio in DOS and Win-OS/2 Sessions
For audio in DOS and Win-OS/2 sessions, you must separately install DOS and
Windows audio drivers from MMPM/2.
The base I/O addresses for Sound Blaster emulation and MPU have to be
the same for OS/2, DOS, and Windows drivers in order for MMPM audio
resource protection to work (see Audio Concurrency Issues below).
Although IRQ and DMA settings can be different for OS/2, DOS, and Windows
drivers, they should be set to the same values.
To enable Audio for DOS sessions, you must set DOS properties to the
following:
AUDIO_ADAPTER_SHARING Required
INT_DURING_IO On
HW_TIMER On
VIDEO_RETRACE_EMULATION Off
DOS_DEVICE C:\JAZZ\JAZZ.SYS P240 I5 D1 E7 T330 Q3
There needs to be a CONFIG.SYS file on the C: drive for the
DOS and Win-OS/2 installation to properly install.
Audio Concurrency Issues - OS/2, DOS, Win-OS/2
OS/2 MMPM/2 is designed such that, when an application is running in
the foreground (has focus), then that application takes priority over
others running in the background. Background applications are put on hold
until they are placed in the foreground (have focus).
When you have a single audio device, it is not possible for two programs
(device drivers) to use the device at the same time. For example, if one
application has the device configured for audio playback, and a second
application configures the device for audio record, the application with
the focus takes priority and the application in the background is placed
on hold. This situation also exists for sampling rate and sample size
configuration.
DOS applications do not participate in MMPM/2 resource management.
When DOS and Win-OS/2 sessions use the audio device, all other programs
are unable to access the audio device.
Audio device drivers for Windows, installed under Win-OS/2, attempt to use
the audio device in all Windows sessions. For Win-OS/2 sessions which do
not use the audio device, you can set the AUDIO_ADAPTER_SHARING property
to "None". This prevents the session from accessing the audio device, and
enables the device to be used by other applications.
