So I installed a Tempo ATA133 card in my Powermac DA (with OWC 1.47 GHvz CPU upgrade) so that it could accomodate a third hard drive. The machine does not seem to recognize it. The card and cables are seated and the drives are configured properly, but I still get the "?" in the start up window. When I go back to the old set up, everything works fine. Anybody have experience with this card? I don't know what I may have overlooked. My machine is currently running 10.3.9. Thanks for any help you might have.
