are no plans to support Win OS/2.

I.  Overview
=======================================================================

A. OS/2 SYSTEM REQUIREMENTS
====================================

   * 100mhz Pentium-compatible CPU 
   * 16MB DRAM (the Vortex hardware wavetable engine uses a native 
     4MB sample set. Samples are stored on disk and swapped to RAM 
     as required. Typical DRAM footprint is <2MB. 
   * 15MB hard disk space
   * CD-ROM drive
   * Good-quality speakers or headphones and connecting cables. 
   * Joystick and MIDI keyboard (optional). 


B.  Known Limitations
=====================

  1. Clock01.sys & Clock02.sys in Warp 4 without any fixpacks applied
  interfere with wavetable MIDI playback.
	Workaround: Install new fixpacks

  2. MMPM/2 MIDI player can't use the MPU for midi playback (it always 
  defaults to WT). Does not happen in Warp 3 and play.cmd works fine.
  This appears to be a bug in the MPPM midi player. The same thing 
  happens with other audio devices.

  3. Unable to uninstall with minstall in Warp 3.  This also happens 
  with other audio devices.

  4. End of (windows) AVI's intermittently hangs -> AnPoCodec problem 
  this happens with other audio devices.

  5. Master volume applet in Multimedia folder only works when a 
  multimedia stream exists. Otherwise master volume commands are 
  ignored.

  6. WarpMix gets out of sync when other applications change the 
  volume/gain/mute and recording source selections while it's running.

  7. To use the 2nd midi device in the Midi player, choose Midi 
  devices -> MIDI 2 in the View menu.

II. Software Installation
=======================================================================

A. DRIVER INSTALLATION 
======================

  1. Uninstall Aureal drivers if present and reboot
  (Delete startup.cmd or remove asp4init.exe)
  2. Run minstall from that driver directory
  3. Install the drivers that show up in the window (Aureal, Wavetable,
  & MPU 401)
  4. Reboot


B.  UNINSTALLING THE DRIVERS
============================

1. Run uninstal.cmd from the original distribution directory
   (which removes AurDmn from the startup folder and starts minstall)
2. Select all drivers in the minstall window
3. When asked, select Aureal Vortex cards and press OK
4. After minstall finishes, reboot.
