Steve, the problem I was having was with the pnp stuff under 2.2.19. When I upgraded to 2.4.12, I was finally able to get my isapnp sb16 recognized as a second sound card. As far as whether you'll get any better results with 2.4.12, isapnp is either recognizing your boards or it ain't. If it ain't broke, don't fix it (smile). Gene
