That is device ID 7861, which is *not* a AHA-2940[U], but a cheaper
version of the 2940U, called the 2940AU. This card, while being
compatible with the existing driver, is basically a 7850 Ultra
controller on a host adapter. It can process at most 3 SCSI commands
simultaneously, as opposed to 16 for the real 2940 adapters (7870 and
7880 based).
You need to patch in recognition for the 7861 in sys/i386/scsi/aic7xxx.c
and sys/pci/aic7870.c. The author of the aic7xxx driver, Justin Gibbs,
is going to be (if he hasn't already) adding this into -current. Don't
know about -stable, though it would be easy enough to do. He doesn't
subscribe to -questions, so you might want to post a question to
-current to see when this is going in.
If FreeBSD isn't installed, then you'll have to wait for the next snapshot
to get a boot floppy that will recognize the 2940AU.
