In MS-DOS, I want to use the Vortex2 for the SB sound effects and a Yamaha YMF-744 for the FM music.

I would like to use the line-out of the YMF-744 into the line-in on the Vortex2.

I can load both their drivers in autoexec.bat, but Duke Nukem3d setup.exe for example, will display a message that it can't detect the FM chip and then freezes the system.

I've tried changing the IRQ and FM ports in both setup programs for au30dos and setupds, with no success.

Does anyone have a setup like this working?
