AFAIK, the 274x/284x/294x driver in Linux supports all of the 294x family,
including the 2940U2W (at least, it was recognized on my system).
The 2940U2W uses UltraSCSI signal levels (LVD=Low Voltage Differential).
Although the documentation indicates that it can drive single-ended as well
as differential devices, I found that it would not drive my older SCSI-2
drives. This is because they require a higher signal voltage.
Unless you have LVD devices, you better stick to the 2940UW for SE devices
and 2944UW for FWD devices.

Hi,
Where can I find a driver for this card?
Does the driver support 2940U2W, as well?
What are the pros and cons of 2940UW vs. 2940U2W?
Thank,
David C. Hoos, Sr.
