-------> OS/2 Warp Business Audio <------------
for the SE1440
This file contains information on how to install the IBM
Business Audio Device driver for the SE1440 in OS/2.
System Requirement for OS/2 Version 2.1
----------------------------------------
Note: This section is for OS/2 Version 2.1 ONLY! If you have
OS/2 3.0 (Warp!) then move on to the next section, "Business
Audio for OS/2 Installation Procedure"
Before you install Business Audio for OS/2, 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) 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 for the OS/2 2.11 service
refresh of February 1994.
The MMPM/2 CSD should be installed on top of OS/2 2.1 and
can be obtained free from Compuserve or from the IBM OS/2
BBS.

Business Audio for OS/2 Installation Procedure
----------------------------------------------
1.Insert the Business Audio for OS/2 diskette in driver A:.
2.Start the multimedia installation program, located in the
Multimedia folder onthe OS/2 desktop.
3.Once you are in the Multimedia installation program,
select Source Drive A: (or whichever drive the SE1440
diskette is in).
4.Select the "Business Audio" icon after it appears.
5.The installation program will update the OS/2 CONFIG.SYS
as follows:
BASEDEV=CSCONFIG.ADD /A:GENERIC /P:530 /I:11 /D:1,1
DEVICE=C:\MMOS2\CS4231.SYS /N:BSAUD1$
DEVICE=C:\MMOS2\VCS4231.SYS BSAUD1$
6.Modify the config.sys, by changint the line
BASEDEV=CSCONFIG.ADD /A:GENERIC /P:530 /I:11 /D:1,1
to
BASEDEV=CSCONFIG.ADD /A:OPTi929 /P:530 /I:11 /D:1,1

Using Audio in DOS and Win-OS/2 Sessions
----------------------------------------
Support will need to be added from Device Drivers that come
with the SE1440.
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
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.
