Here is a simple batch file to get around the Protected mode program's
IRQ/DMA limit:

@ECHO OFF
C:
CD \DOOM
SET TVAR=%ultrasnd%
SET ULTRASND=220,1,1,5,7
C:\ULTRASND\ultrinit.exe -o -l
DOOM %1 %2 %3 %4 %5 %6
SET ULTRASND=%tvar%
C:\ULTRASND\ultrinit.exe -o -l
CD \

I'm assuming here DOOM and your ULTRASND directory is on your C drive.
