Johan,

I just had this problem and a look in the archives suggested a conflict
between the Adaptec card and the computer.

I had a 2940U in another computer which I replaced and worked.
Then I installed the 2940AU where I got the 2940U from and it also
worked in THAT computer.

I recommend you try to get a different controller, preferably either a
different model (i.e 2940U) or a different brand all together, like
Roger suggested. My search in the archives did not find a single person
that got things to work without changing the card after having got the
"board not responding" error from their Adaptec.

The 2940U I used is over a year old so I don't know if newer 2940Us
would work.
In case you are not aware the difference between the U and the AU is
that the U is an OEM controller, other than that they should be almost
identical. I say almost, because I found at least one difference in the
SCSI select betweent the two.

Good luck.
