The on board PDC20378 is not a true hardware RAID. But, yeah this is the
problem. There is no device created. The controller is supported and has
a driver, and supposedly has had a driver since the 2.4 kernel. The
system detects the card loads the driver but can not find any devices. I
am not expecting to find one RAID device created, I know its a software
RAID controller ( basically ) I don't care, I just want to be able to
use the controller.

It looks like the driver is only recognizing the SATA port on the
controller and not the PATA port. You can use either or. So it sees the
controller but no attached devices.
