I had tried that too. No go.
Here is what another person had mailed me about his experience using the
2940UW and FreeBSD:
!! At the time I was using an Acer AP53-R3 (HX) Mainboard. As it turned out
!! although I was quite reluctant to do so, I borrowed another mainboard
!! (Asus) and poof. It booted without problem. It was quite distirbing as
!! Linux (Slackware and RedHat) both responded okay, Windows 98 responded
!! okay but FreeBSD crashed....
In diagram terms, here is what I have:

This drive has
FreeBSD 2.2.2 already
installed on it via a
2940AU card. It does boot
via a 2940AU card. Thus it
should boot here with the
2940UW. I get the boot prompt,
then it hangs after waiting
for SCSI devices to settle.
I have:
Tried setting the LOW/HIGH manually. No go.
Set the TE to Power from the SCSI bus. No go.
Leave the setting to Automatic. No go.
Only the narrow drive on the card. No go.
Only the wide drive on the card. No go.
I conclude, particularly after the response from the one user, that
there is something wrong with the FreeBSD 2940UW driver with _some_
mother boards. Which, unfortunately, I see to always have.
Any pointers, ref's?
Roger
