Does the HP have a status monitor? If so, what does it say? Do you have access to a SCSI bus analyzer? What does a boot -v tell you about the termination of the card? Does it appear to be correct? Does the behavior change if you use a manual terimination setting in SCSI-Select? -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
