It's total crap. Ring Adaptec back, get hold of their support supervisor, tell them that one of their reps just blew it (indirectly) in a public mail forum with <insert -hackers readership number here> readers. If you have the rep's name, give them that too. You may have problems with the translated geometry reported by the 2940 and 1542 being different, but if you've managed to get the kernel read in, that's not an issue. > Jonathan M.
