The plan has always been to migrate the SCSI knowledge in the XPT layer into a 'personality' module leaving the generic portions of the CAM XPT intact. The personalities would be compiled in using the "atapibus0" and "scbus0" keywords in config. I don't think it would be that hard, but it would require time I don't have right now. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
