I'm more concerned about SCSI bus addressing being a problem. Perhaps the statement above means that each card can have a distinct ID on the bus. My experience with SCSI is pretty much limited to systems where the host computer is hardwired as device 0. If these cards are like that, they'll likely be pretty confused about who's who. -- Walter M. Pawley Wump Research & Company 676 River Bend Road, Roseburg, OR 97470 541-672-8975
