Do you wish me to reproduce:

1. The source code for the Aureal drivers (impossible)

2. The source code for the Allegro sound driver (20k)

3. The source code for PmodeTSR kernel (130k)

4. The source code for the CWSDPMI kernel (length unknown)

The reason I asked was to see if anyone knew of any differences
in the design of CWSDPMI regarding the way IRQs are dealt with
compared to other DOS extenders such as DOS4GW and PMODE, which
was designed to replace DOS4GW.

No.  Good idea.
