(of > course, it cancels the reservation at final close) Great, but the DPT controller does that in the firmware already. I cannot wait to move the driver to CAM, but no time so far :-( If you have (something I asked Justin for :-) a list of API routines the CAM produces ( a brief ``what it does'' will be great!), and entry points expected of a driver, you will xut my development time by a week or two. ---------- Sincerely Yours, Simon Shapiro Shimon@Simon-Shapiro.ORG Voice: 503.799.2313 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
