Anyway, just wanted to know if this is - and it seems so - an extra 'wired' interrupt. Enabling the NMI/Parity jumper leads to and immediate BIOS halt from Win95 when the card is accessed. OK, I don't want you to burden with Win95 problems. Just in case someon stumbled accross this before. > protected-mode drivers in DOS (I think). If audio works in DOOM you can > ignore this.
