SUCCESSFUL GUS INIT FILE CONFIGURATION FOR ID/3DREALMS GAMES 
============================================================ 

...Here are the files I used to finally get the GUS to work with all 4 ID 
games: Ultimate Doom, Doom II, Heretic, and Hexen. This setup, amazingly, will 
also work with Duke3d! 

Some notes:

1. You *must* run the IWSBOS batchfile included in this package every time you 
run Heretic or Hexen after running Ultimate doom and/or Doom II, no matter 
what the Heretic/Hexen sound configuration currently is. If you don't, the 
sound card won't work correctly. 

2. Setting the SFX option to 16-bit Gravis Ultrasound gives you 
"locationatory" sound; i.e. if a monster growls from your left, you will hear 
it in the left speaker. With normal 8-bit Soundblaster sound, you get the SFX 
but no locationary sound. You *cannot* have both music *and* locationary sound 
together from a 16-bit sound card (you have to have a 32-bit sound card for 
that). If you set SFX for GU and music for General MIDI, GU will override and 
you will only get locationary sound. To hear the music, you *must* set the SFX 
to plain Soundblaster. However, I have set the Heretic/Hexen/Duke3D 
configuration files so that you can switch back and forth using SETUP, without 
running IWSBOS (unless you just ran Ultimate Doom or Doom II), at will (for 
Duke3D, see note 3 below). 

3. I have set the MPU401 IRQ to be the same as the Ultrasound IRQ in 
IWDOOM.INI, because Duke3d works with it that way, and it doesn't seem to 
affect sound in the ID games. Note, however, that if you switch SFX to 
Ultrasound in Duke3D setup, you *must* disable General MIDI, or the card will 
hang (unlike the ID games, where you can leave it at GM and it won't affect 
anything). 
 
4. If you run a game and the music's playing out of only one speaker, quit, 
run my IWSBOS, and try again.

5. The DOS paths indicated in my init files are for my system only; you will 
have to edit these paths so that they point in the right direction for your 
system.
  
6. Everything that I have described here is for DOS *only* - because I haven't 
figured out how to get Windows 95 to release the GUS for a DOS session 
temporarily, I currently do not have sound in a win95 DOS box.
