EDIT - I tried running UNISOUND /D before returning to Windows, and it does actually work now! Is there any way to automate that though? Commands run when ending a DOS session started via PIF, rather than when starting?

Windows swaps out the autoexec.bat and config.sys files for the custom ones set in the PIF file when you use the short cut and then swaps them back after you return to windows mode.

To make commands run only when windows starts, edit C:\AUTOEXEC.BAT after windows has loaded.

Edit: After you add the UNISOUND/D to the windows autoexec.bat and you have the whole shebang working, you can copy the shortcut to "C:\WINDOWS\Exit to DOS.pif" and it will also use those settings when using Shutdown -> Restart to MS-DOS.
