Ok, normally I'd not bother with this kind of message, but Brian (Haymore)
has been both nice and helpful in my experience, so I'm going to do a
little sticking up for him since he's being uselessly railed on :)
Note that I specifically hate flaming that doesn't get taken off-list,
but as I correct factual error(s), I believe this is still valid for
linux-raid. With that said, on with the show. :)

Same message *I* was about to send about my DAC-1164P's too :)

This didn't matter. What you *specifically* said in message
<[EMAIL PROTECTED]> was

and "LVD is for the new U160 protocol" is clearly a board-independent
(and factually incorrect) statement. (How incorrect? See below)

Don't see what price has to do with fairness here. True the original
thread is about the 2940U2W (not that it ends up mattering, see
below), but you were responding (initially) to a message that was
much more SCSI-generic (active/passive termination WRT the terminator
[EMAIL PROTECTED] had bought at a computer store)... but, I digress.

Glad you cleared that up... Can you correct Adaptec?
I guess they don't know the hardware they build :)

Q: What is the SCSI Card 2940U2W?
A: The SCSI Card 2940U2W (or AHA-2940U2W) is the latest in the line
of Adaptec PCI host adapters. It has the latest SCSI Ultra2 technology
which uses Low Voltage Differential (LVD) circuitry designed into
the CMOS to provide a bandwidth that is up to twice the current Ultra
speeds and with cable lengths up to 25 meters.
They get it "wrong" in other places, too, like listing the 2940U2W
under the "Low Voltage Differential / Ultra2 PCI SCSI" section
at http://www.adaptec.com/support/files/drivers.html
(Don't they know that "LVD is for the new U160 protocol"?)
> Adaptec also does not specifically support Linux the way Mylex does.
Maybe you talk to Ledford about what level of interaction he has with
Adaptec engineers and rethink this statement :)
HTH, HAND,
(wow, that *was* therapeutic!)
