		Unofficial Gravis Ultrasound OS/2 Driver


1. Introduction.
     This is a first pass at GUS physical driver for OS/2 MMPM. It has
   just basic WAV playing capability. It works in conjunction with
   the Digital Audio player and system sounds.

2. Installation.
     Simply unzip the file into a directory and run MINSTALL. It does
   the rest. You are given the choice of letting MINSTALL change
   your CONFIG.SYS. I wouldn't let it do that. Let it create a
   test file in \MMOS2 and compare that with your config.sys file
   to make sure nothing went wrong. Besides you may want to change
   the base and/or interrupt assignments first.

   The base and irq defaults are what work for me. You may want
   to change them (the DMA in particular).

   The install file creates a wave player object in the multimedia
   folder. If the GUS is installed as a second (or third..) MMPM
   wave device, the the parameter field in its settings has to
   be modfied to include "Waveaudio0n", where n is the number of
   GUS device. Generally this would be Waveaudio02.

3. Known bugs.
   a. It doesn't record.  Later!
   b. Clicks. They can get annoying, but, from what I heard, fixing
      them could be a lifelong job. Trial and error seems to be the
      primary method here.
   c. MIDI is not supported. This will take a while!
   g. It does not play stereo WAVs properly.

4. Feedback.
     This is a first pass and I wanted to get something out to
   give everyone hope.  I know about enough problems to keep me
   busy for a while. So please, think before sending me a message
   telling me about something in the known bugs list. In fact, until
   I get out a 0.1 release, could we limit negative feedback to
   show-stoppers.  Also, I have a 486DLC system. I have had no other
   opportunities to try this on other systems. There is a chance that
   it will not run on your system because of some incompatibility I
   didn't anticipate.  Please be patient with this sort of problem, as I
   have limited resources to deal with different machine configurations.
   
   The following e-mail address is my work address.  I might have
   some problems if a huge amount of mail starting appearing, so
   think first.

   On the other hand, as an aid to deciding if a problem is
   configuration related, a note describing your successful
   use of the driver would be appreciated, if accompanied with
   a description of your configuration.

   The address to reach me is ernst@tymnet.com (yes, in real life,
   I work on software for the Tymnet Public Data Network. I do X.25
   stuff and 680x0 based firmware.)
