Hello, I am hoping someone here can help me out or point me in the right direction to help myself. I have inherited a beige PowerPC G3 Mac which works great with OS 8.5/6 When I install Mac OS X (legally purchased from a Mac dealer) it loads the first install disk and then reboots. On rebooting I get the happy Mac icon and then it goes to a white screen with black lettering and repeatedly says it "cannot OPEN /pci/Apple53C875card at D" I know just enough about Open Firmware to be able to see that it is looking for the SCSI controller and apparently cannot find the drive. When I use Disk Utility during Mac OS X installation it says I have a Quantum Viking 4.5 WSE 4.24GB drive on the SCSI Bus with a LUN of 0 and an ID of 0. How do I modify OF to look for the hard drive so it will boot properly? Thanks in advance for your help. Rick Carlson
