I've been trying to confirm that any of the successes have indeed been
with multiple Ultra-160 LVD drives. So far it seems at least one such
indication of success proved to be with one or more lesser drives.

Ah! I haven't looked at it in that long! ;-)
But this is very good news -- it suggests the current version is quite
stable (and my own use of it confirms that for at least one setup).

Justin Gibbs seems to have a very good handle on how to talk to those
chips. Do you know if he was able to get docs from Adaptec?

I just realised that even if I found the time to do that learning and to
do the re-port, I don't have any hardware to do it with anyway -- all
the machines I did the initial testing on are now in production at a
client site..... I personally can't afford my own STL-2 or similar
system at the moment, even though I'd really like one, and I don't
really want another PCI adapter board, nor do I have any appropriate
disks for testing anyway.
