I have a number of both of these types of these controllers running on several different FreeBSD systems here. In general, I find the 2940's to be more tolerant of long cables/many devices and the 810's (plus driver) seem to work better with my older Exabyte (EXB-8200) and Wangtek tape drives. -- Bob Willcox politics, n: bob@luke.pmr.com A strife of interests masquerading as a contest of Austin, TX principles.
