I noticed your post a few days back and wasn't sure of the answer. Well
after several emails between the team member who handles the SCSI
driver here is an answer. I think you and I have the same exact
motherboard.
You don't have a 2940. A 2940 is Adaptec's stand alone PCI card
based on the aic7870 (or 7880 if its an ultra model) chip. The
motherboards that use aic7xxx chips either use an aic7850, and
aic7870, or an aic7880. The aic7870 and 7880 are supported. The
7850 (which is a pared down 7870) is not supported yet and that is
what is on your motherboard. There are a lot of vendors that pawn
their MBs off as having a "built in 2940", but the truth is that
the 7850 doesn't have the same performance as a 7870 based board.
Hope this info is what you wanted. As of right now there is no driver
available that properly handles the 7850, but it is in the works.
