Known problems:
===================================

The default IRQ setting for the Gravis Ultrasound is IRQ 11. DOOM does
not support any IRQ above 7. Change the IRQ to 7 or below.

Doom requires that you have installed the General MIDI patch set from
the 2.06a Install Disks (or later) that came with your UltraSound (and are
also available via FTP and BBS).  DOOM will find your patches (using the
ULTRADIR variable) in the MIDI subdirectory pointed to by ULTRADIR.
    example:  SET ULTRADIR=C:\ULTRASND

If you experience frequent lockups AND have less than 1024K of
GUS RAM, try upgrading to 1024K (1 Megabyte).

===================================
Basic sound setup:
===================================

1. Delete the default.cfg file in the DOOM directory if it exists).

2. Go to the sound card directory and run any diagnostic/setup software
	that came with the sound card. If everything checks out, make a note
	of the sound card settings.

3. The DOOM setup can automatically configure your system providing you 
	have the 'BLASTER' environment variable set in the autoexec.bat. To
	set up the 'BLASTER' environment variable, take the PORT/IRQ/DMA
	settings made a note of in the last step and fill in the 'SET BLASTER'
	stament below:
	
	SET BLASTER=A<PORT> I<IRQ> D<DMA>
	
	Where	<PORT>	= Three digit I/O port address
			<IRQ>		= One digit IRQ 
			<DMA>		= One gigit DMA CHANNEL	

	The IRQ must be 7 (5 is recommended) or below. DOOM does not support
	any IRQ above 7.
	
	The DMA channel must be 3 or below (1 recommended). DOOM does not
	support any DMA above 3.
	
	After you have added the 'SET BLASTER' statement to the autoexec.bat,
	reboot the machine.
	
4. Go to the DOOM directory and type setup.

5. Highlight the 'Choose Sound FX Card' option and press enter.

6. Highlight the appropriate sound card and press enter. If your card is
	not listed, it MUST be 100% HARDWARE compatible with one of the listed
	sound cards or it may not work (This does not include sound devices that
	connect through the parallel port or sound cards that provide 
	compatibility through a software. Such devices will not work at all).

7. Select the port address, irq, and dma settings that match your sound
	card settings.
	
8. From the main menu, save settings and run DOOM.

*NOTE: If your sound card is not 100% hardware compatible with the Sound Blaster or it is not listed in the setup, we can only suggest getting a
real Sound Blaster or another card listed in the setup.

======================================================================

There is no known problem with the Sound Blaster sound card. If you are
having a problem, and following the above instructions without success,
