Can you steer me to the URL for Creative soundfonts?  I found all sorts of 
fonts at one other site but only the synthgm.sf2 and the 3.5M one worked 
at all.

In DOS, with ctcm, I disabled the extra on-card IDE controller.  This was 
a lot simpler for me than using isapnp, but the latter should work too.

My ethernet is pci/pnp but my modem is ISA so I might also set BIOS to 
IRQ 3 ISA/EISA.

I did not need to set DMA1 ISA/EISA - would this help in some way? Also 
DMA 5 (high dma, dma16) is used by the sound card.  The DVD-ROM DMA 
conflict disappeared by just setting IRQ5 in BIOS to ISA/EISA.  I might do 
this to my other computers with SB16 cards (set IRQ5 in BIOS) to see if it 
speeds up mounting CD's.

'should' but not 'will'.

In a computer with a jumpered sound card I had no problems.
