Only have your OS drive installed.
To boot into Open Firmware, shut down your Mac, then start it up while holding down the
Command, Option, O and F keys. At the prompt, enter the following commands, pressing

Otherwise if it refuses to pick up anything on the SATA ports then it could be a dead controller.
Try looking on ebay then for a Sonnet PCIe SATA card. I'm thinking of getting one
myself and an addition drive cage for a few more internal drives...
Also if you can, pick up a standard PC Nvidia 7800GT/7900GTX.. But you're on your own regarding firmware
