I was just there, and noticed that the latest version:


Is mode 640, so I can't access it (not that I have an immediate need -
we're still trying to decide what kind of SCSI controllers to get).

And, sorry to keep asking so many questions, but...

1) I notice in the README in this directory, that as of the writing time
   (April 10) the porters hadn't received any report of successful
   operation on a 3940 (dual channel) controller. Has anyone tried this
   yet? If not, does anyone have an idea how much work it might take
   to *make* it work if it doesn't already?

   Adaptec just announced an Ultra-Wide version of this controller
   (3940UW - see ), which
   could turn a NetBSD machine into a really great disk array.

2) There was also no mention of it working with a 2940UW. I assume if
   it works with 2940 and 2940W, it would also work with UW, but
   would rather make sure.

3) I have only located 2 places which sell motherboards with integrated
   Adaptec controllers. Anybody have phone numbers / web sites? (We have
   needs for 2 types of machines - NFS servers with tons of
   striped/mirrored disk, and compute servers with a single disk for swap
   and binaries - the latter would do just fine with the right *fast* CPU
   and onboard SCSI controller.)

4) Should I even attempt to put this driver on a 1.1 release system, or
   have there been enough changes that I need to do -current? If so,
   has there been any talk yet about when another official release might
   be done?
