I have a DELL PowerEdge XE 51. It has a DELL array controller running
on EISA buss. The controller is uses a AHA-154x emulation. I am using
RedHat 7.0 and it does not see the board. Where can I get a EISA buss
AHA-154x driver to access the array controller?

David, Dell never produced a Linux device driver for the Dell SCSI Array
card. I had forgotten about the AHA-154x emulation feature, but since it
doesn't seem to work, it's unlikely that it ever will. Everyone who worked
on that project 9 years ago has left for other opportunities. The on-board
NCR SCSI controller should still work, and you can use software RAID quite
easily to accomplish similar functionality.
Thanks,
Matt

The EISA bus AHA154x equivalent is the AHA174x which we do support. I don't
know what the Dell arrays used however
I know at a minimum...those cards can be put into a 154x mode, so it
will work. I remember that NetWare needed this feature.

If they are AHA147x based then the 154x mode has emulation errors and Linux
specifically avoids using 154x drivers on them.
I believe this is the case on these particular controllers. They are in
fact 147x controllers, with a 154x emulation mode. I used to support
lots of legacy equipment at Dell, and I believe that's the case, but if
Matt wants to chime in to confirm that or not, would be helpful. There's
lots of info on this as I believe there are still plenty of customers
actually still using 4100's and the like.
