I installed an ISA Speedstar and disabled the video card on the motherboard. Now I get static when playing audio in DOS, and 16-bit audio doesn't work in Win'95 (just freezes the computer).
I've tried excluding a000-c7ff in emm386, and half a dozen other suggestions, but to no avail.
The latest drivers I just downloaded help none.
The video card on the motherboard doesn't do this.
