Peacemaker,
I think you could start with the DTS. You already made the change to 2 SATA ports in the driver. But the DTS needs another entry for the 2nd port. The things to look for is the settings in that entry. I don't know how hard it is to find it in the GPL for this box, but I assume it is possible.
:) and if you had a Kirkwood device, then it would have been a lot easier.
