Why? It works like a charme.
You just need more DOS-foo than the average Win-User (Post 9x) to get it running flawlessly.
do a 3.11 install on DOSBox while still half asleep waiting for my coffee machine to make me some "Potion of Resurection".
If you want the SB drivers inside Win3.x you need to run the DOS installer... sounds weird, but the Creative DOS installer detects Windows and places the drivers inside it and edits the win.ini for you.
I am not at home currently and cant access my machine trough NX because its off, otherwise i would have uploaded the driver for you, drivers are free for distribution anyways. And while i am at it i would upload WinG, Win32s and Intel Indeo too.
BTW, i use that setup to play Die Total VerrÃ¼ckte Rally and Battle Isle 3 from BlueByte.
Both won't run on modern Windowses and not even in WINE, but they run flawlessly on DOSBox with Windows 3.11.
