[Took a while to answer but I am in the Dominican Republic at the moment] The Plextor will run at 20MHz, IIRC, but not your controller. Do a "man ahc" and search for 7870 two times. You will find it listed as a 10MHz controller. I doubt you will find any device negotating at 20MHz on your machine :-) Regarding the Plextor, I can tell you if it is running at 20MHz as soon as I am back next week but I am 99% sure it does... -Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
