Since I was working on the 3174 today anyways, I flashed the logging 
firmware and traced the accesses that occured (on disk drive 2 for the 
extension disk, for a control disk IML, for the people to whom this 
means something). Anyways, that's a 2.4M disk. The trace can be found at 
[2]. It isn't very detailed though. I don't think this will help much.
