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".

Attention PS/1 owners - follow the instructions under
"Aria Audio Installation for OS/2" (below). This device driver			
was specifically tested ONLY on the Aptiva systems.

SETUP
------
This installation requires OS/2 WARP version 3.0 or later.  This device
driver requires the IBM OS/2 Aptiva Update diskette when installing on an
Aptiva system. To obtain an update diskette in the USA call IBM Support at 1-(407)-994-5544.

This is IBM's Voice Recognition Unit (VRU). Select the following options:

Technical Assistance
  OS/2 or Pen for OS/2 Support
    OS/2 Warp on Aptiva
      To record on the Update Voice Mailbox
     Leave your Name, Mailing Address, Phone Number and type of media needed.

1: Ensure that the Aptiva Update Diskettes were installed.

2: 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

3: 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>.

4: SHUTDOWN and REBOOT

ARIA16 Audio Installation for OS/2
------------------------------------------
From the Multimedia folder, double click the Multimedia Application Install
Icon. Insert the Aptiva Aria16 Audio diskette in drive A:and select source
drive A: highlight "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.

DOS
-----------------------------------------------------------------
The following 2 lines need to be added to the DOS_DEVICE settings
for any DOS session that requires audio. These drivers are shipped on
the Aptiva Preload and may not be present on other systems. 


C:\ARIA\BIN\SOUNDCFG.SYS C:\ARIA\ARIA\ARIA.CFG 290
C:\ARIA\BIN\SNDSAVER.SYS /R290


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.

2. This driver does not support Advance Power Management (rapid resume).
