To get your old Aztech sound card working in Windows.. Install your sound card.. Then install DirectX6.1.. If you have DirectX installed, just Reinstall it.. It will install the latest Aztech driver for your card..

And for DOS support.. just add to your autoexec.bat file..

setblaster = a220 I5 d1

I believe that is correct.. You don't need to put the Setblaster command in your autoexec, to get sound from Dos thru a Dos box in Windows.. Only in True DOS mode..

I hope this helps..
