I have a HP surestore CD writer (fast scsi), a Scanjet IIc (scsi), an archive DAT autoloader, and a Micropolis 3387 (ultra scsi) all on the same bus with no trouble. I even had a zip drive on this bus at one point. Furthermore, the 3387ns is even improperly cabled (connected to the 25 pin side of the HP scanner). I still get the 20mb/sec transfer rate and no errors. If it isn't working, you've either got a defective card, incorrect configuration, stale bios or driver, horribly defective cables, or bogus termination. -- Brian Ristuccia brianr@osiris.978.org bristucc@baynetworks.com bristucc@cs.uml.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
