I am trying to add additional SATA drives to my G5 ( Leopard ) so I purchased a Sonnet Tempo-x esata 4+4. I put in the card and it was detected initially but when I copied files over to the SATA drive, it would lock up the OS. So i searched on Sonnet's website and I installed the 2.2.4 software . The pkg installed fine. It wanted to reboot after it completed. I clicked the restart button. Then a pop up says it will write to boot cache and when it is complete it will reboot. I clicked OK and let it do its thing. On reboot, the card shows up only as a PCI device that has no driver. So I tried it again, this time I noticed after I ran the package install before the reboot that the card is recognized and I can access the SATA drive. Once the server reboots though, the card is not detected again. Anyone have a clue what's going on and how to get Leopard to see the card. I don't want to run the software updater every single time to access the SATA drive. I have tried resetting the PRAM. I did not find the PMU reset. This is a single 1.8 G5 PCI-X.
