README - Prometheus Audio Device Driver (ARIA16) Aptiva Installation
----------------------------------------------------------------------
This readme file contains information on how to install the Aria16
audio device drivers for OS/2 on an IBM Aptiva.


SETUP
------
This installation requires OS/2 WARP version 3.0 or later.  This device
driver requires the IBM OS/2 Aptiva Update diskette. To obtain an update
diskette call IBM Support at 1-800-765-4747(USA) or 1-800-565-3344(Canada).
If you are having Audio problems with WINOS2 and the ARIA 16 card also
contact the appropriate 1-800 number shown above.


1: REMark the following lines in CONFIG.SYS

   DEVICE=C:\ARIA\BIN\SOUNDCFG.SYS C:\ARIA\ARIA.CFG 298
   DEVICE=C:\ARIA\BIN\SNDSAVER.SYS /R298
   The above lines should look like the following example:
   REM DEVICE=C:\ARIA\BIN\SOUNDCFG.SYS C:\ARIA\ARIA.CFG 298
   REM DEVICE=C:\ARIA\BIN\SNDSAVER.SYS /R298

2: Open OS/2 window.
   At the C: drive type cd OS2\boot  <enter>.
   Type attrib -r clock01.sys  <enter>.
   Type attrib -r clock02.sys  <enter>.

3: SHUTDOWN and REBOOT

Aptiva ARIA16 Audio Installation for OS/2
------------------------------------------
To install device support, insert the Aptiva Aria16 Audio diskette in drive
A: and type MINSTALL from the A: drive. Select "Aria Audio System 16" and
select "install".

The Aptiva Aria16 Audio device driver installation adds the following 3
statements to your CONFIG.SYS file:

        DEVICE=X:\MMOS2\TIMER0.SYS
        DEVICE=X:\MMOS2\ARIA16DD.SYS /B:290 /I:10 /M:330,9 /N:ARIA161$
        DEVICE=X:\MMOS2\AUDIOVDD.SYS ARIA161$

        X: is the drive where MMOS2 is installed


The following parameters are valid for the ARIA16DD.SYS driver:

        PARAMETERS              VALID VALUES         DEFAULT
        ---------------------   ------------------   -------
        Base I/O port address   280, 290, 2A0, 2B0   290
        Aria Interrupt level    10, 11, 12           10
        Midi Port               320, 330             330
        Midi Interrupt level    5, 7, 9              9



SHUTDOWN and REBOOT


Using Audio in DOS and WIN/OS2 Sessions
----------------------------------------
To improve audio in DOS and WINOS2 sessions, set the following DOS
properties:

   AUDIO_ADAPTER_SHARING    Required
   DOS_HIGH                 On
   HW_TIMER                 On
   INT_DURING_IO            On
   VIDEO_RETRACE_EMULATION  Off
   XMS_Memory_Limit         7000k


Audio Concurrency Issues - OS/2, DOS, Win-OS/2
----------------------------------------------
Using a single audio device, it is not possible for two programs
(device drivers) to use the device at the same time.

DOS applications do not participate in MMPM/2 resource management.
When DOS sessions use the audio device, all other programs are
unable to access the audio device.


Problems
---------
1: When opening a WIN/OS2 session an error is generated, "Midi Error".
   Select "Don't display this warning in the future". Click OK.
   Please ignore this message.
