I guess my answer was a little confusing, so here it goes again:

Yes: the program uses the BLASTER string to set the IRQ, DMA and other 
things it uses. The Sound Blaster 8 had only 1 DMA, and it was indicated 
by the D#, that is: use the 1st DMA. A is the base i/o address, I is the 
IRQ. 
The SB-16 has 2 DMAS, so it adds the H# to indicate the second DMA.
It also adds the P# for base midi, i think.

Since the program doesn't expect that (and doesn't need it anyway, it 
ignores it, and tells you your BLASTER environment has strange things in it.

Hope i got it straight this time.
