This readme file contains information on how to install the Reveal
SC500 FX Wave or SC400r4G FM synthesis sound cards on OS/2 Warp.

System Requirements  *** IMPORTANT ***
------------------
Before you install the Reveal SC500 FX Wave or SC400r4G, make sure 
that you have first installed OS/2 WARP Version 3.  You must also 
insure you have removed any previous sound board support through 
the selective install option in System Setup.


Reveal SC500 FX Wave or SC400r4G Installation Procedure for OS/2 WARP
----------------------------------------------------------------------
To install device support, open an OS/2 window or full screen session 
and insert the Reveal SC500 FX Wave or SC400r4G Support diskette 
for OS/2 diskette in drive A:. 

1.)Type MINSTALL from the source drive "A:". 
2.)Once in the Multimedia installation program, select Source Drive A: 
(or whichever drive the Reveal SC500 FX Wave or SC400r4G Support disk
 is in)

Select "OPTI Crystal SEMI WAV Audio" to install WAV audio support.
Select "OPTI OPL3 MIDI" to install MIDI support.
Select "Crystal SEMI Windows Audio" to install WINOS2 WAV support.
    
	** Windows audio should not be installed over existing **
	** WINDOWS audio support. This WINOS2 install driver   **
		** works in both WINOS2 and Windows        **

The Multimedia installation program adds the following statements
to your CONFIG.SYS file.  These statements are displayed as
follows:

BASEDEV= MAD16.ADD MODE:WSS BASE:604 WSSIRQ:7 WSSDMA:0 SBIRQ:7 SBDMA:1
	    CDTYPE:S CDBASE:320 CDIRQ:9 JOYSTICK:1
**NOTE - above BASEDEV line MUST immediatly precede the LIBPATH line **
   DEVICE=C:\MMOS2\CSBSAUD.SYS N:CSAUD1$
   DEVICE=C:\MMOS2\VCSBSAUD.SYS CSAUD1$
   DEVICE=C:\MMOS2\VMAD16.SYS CSAUD1$
   DEVICE=C:\MMOS2\TIMER0.SYS
   DEVICE=C:\MMOS2\OPL3.SYS /P:388 /N:OPL31$


Reveal SC500 FX Wave or SC400r4G Audio for WINDOWS and WINOS2
---------------------------------------------------
Any WINDOWS Audio support must be removed before installing
the Reveal WIndows Audio for WINDOWS and WINOS2. To do this
backup the SYSTEM.INI and remove all audio references.


OS/2 WARP Installation from CD ROM connected to Reveal Audio Card
------------------------------------------------------------------
To install OS/2 WARP from a CD player connected to a Reveal SC500
FX Wave or SC400r4G Audio card, the MAD16.ADD file must be added
to the OS/2 CD Install Disk 1 manually.
Make a diskcopy of the second installation diskette and edit the 
config.sys file on it by adding the following line.  Don't forget to 
copy the MAD16.ADD file to the modified diskette.  BASEDEV=MAD16.ADD 
line also needs to be added to the CONFIG.SYS statement.

 1) Copy MAD16.ADD to OS/2 WARP CD Installation Disk 1
 2) EDIT config.sys to add the following line immediatly after the
    LIBPATH= statement:

   BASEDEV=MAD16.ADD CDTYPE:X CDBASE:XXX CDIRQ:X

   CDTYPE:S, P, M, I

	  S - SONY CDU-31A/33A
	  P - PANASONIC CR-522/523 CR-562/563
	  M - MITSUMI FX001/FX001D
	  I - Generic IDE (DEFAULT)


   CDBASE:   None, 320, 330, 340, 360 (default based on CDTYPE)
	     Sony31A   - 320, 330, 340, 360 (default 320)
	     Panasonic - 330, 340 (default 330)
	     Mitsumi   - 320, 340 (default, 320)
	     IDE       - 170      (fixed)
	  CD-ROM device drivers accept "/P:xxx" to specify a base port

   CDIRQ:    None, 3, 5, 7, 9, 10, 11 (default based on CDTYPE)
	     Sony31A, Mitsumi (All above choices are valid)
	     Panasonic - None (polled device, no interrupts)
	     IDE       - 15 (fixed)
	  CD-ROM device drivers accept "/I:x" to specify an interrupt.
   
	3) Install OS/2 Warp (be sure to install multimedia software
	   support)
	   ** The Reveal Audio card is detected by OS/2 install
	      as an SB Pro - Remove this by clicking on Multimedia
	      from the System Configuration menu and select remove
	      from the Device Selections and Settings menu **
	4) Follow the Reveal Audio Installation Settings above

**NOTE**  The CD ROM device drivers for PANASONIC CR 562/563 and
	  IDE cdrom drives that ship with OS/2 WARP for Windows,
	  do not work when used off a sound card. The drivers that 
	  ship  with OS/2 WARP "FullPack" fix this problem, 
	  they are included on this diskette in a CDROM subdirectory.
	     
  NOTE:   PANASONIC SBCD2.ADD REQUIRES "/P:XXX" FOR PORT ADDRESS
	  IN THE CONFIG.SYS  Add this parameter to the end of the 
	  existing line in the config.sys 



Generally, the default settings selected by the installation program 
will operate the sound card properly.  However; should you have 
special considerations, here are the settings you can modify manually.



MAD16.ADD
---------
The Options to MAD16.ADD are:

 MODE:  wss, sb            (default Windows Sound System)
 BASE:  220, 240           (for Sound Blaster mode, default 220)
	530, E80, F40, 604 (for Windows Sound System mode, default
	530) Choosing 530 or E80 for WSS gives 220 for Sound Blaster.
	Choosing 604 or F40 for WSS gives 240 for Sound Blaster.
	E80 and F40 are valid only with version 929 of the OPTi part.

   CDTYPE:   None, Sony31A, Panasonic, Mitsumi, IDE (default None)
	     One character is adequate (e.g. CDTYPE:S)

   CDBASE:   None, 320, 330, 340, 360 (default based on CDTYPE)
	     Sony31A   - 320, 330, 340, 360 (default 320)
	     Panasonic - 330, 340 (default 330)
	     Mitsumi   - 320, 340 (default, 320)
	     IDE       - 170      (fixed)
      CD-ROM device drivers accept "P:xxx" to specify a base port

   CDIRQ:    None, 3, 5, 7, 9, 10, 11 (default based on CDTYPE)
	     Sony31A, Mitsumi (All above choices are valid)
	     Panasonic - None (polled device, no interrupts)
	     IDE       - 15 (fixed)
      CD-ROM device drivers accept "I:x" to specify an interrupt.

   SBIRQ:    5, 7, 10, 11 (default 7)
   SBDMA:    1, 2, 3 (default 1)

   WSSIRQ:   7, 9, 10, 11
   WSSDMA:   0, 1, 3 (default 1, avoid 0)

       NOTE: The WSS IRQ and DMA are specified here, but can be reset
	     by the audio PDD when it loads.  Optimally, the audio
	     PDD will query MAD16.add to learn of the device settings.
	     As of this writing, this communication does not exist.

   JOYSTICK: 0, 1  (default 1, joystick enabled)





Using Audio in DOS and Win-OS/2 Sessions
----------------------------------------
To improve audio performance in WINOS2, the following setting
modifications may be necessary. These changes can be made from the
settings folder of the WINOS2 application.

   AUDIO_ADAPTER_SHARING    Required
   HW_TIMER                 On
   IDLE_SENSITIVITY         100
   INT_DURING_IO            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.
