Installed two of the PCI Express cards in slot 4 and 3, and then in 2 and 3, to run the Seritek 4 bay drive, but the cards nor drives show up in System Profiler. They do show up as Unknown Other Mass Storage Controller in the Expansion Slot Utility, running as 1X. Any ideas?

I did have the Drive unit working fine in a G4 with the SeriTek external 4 port PCI card.
