The Bt445S is a good choice. WIll this have the same 16Mb limits that the ISA controller has (due to bus addressing restrictions)? Well, this particular controller will since it has broken DMA handling (they keep claiming to have fixed it, but subsequent tests always show "no, not yet! keep trying, guys!").
