Is there a way to tell what the specific problem is with the following scenario? Can someone please help. I got the iMac G5 install and recovery discs that ship with an iMac G5. I have an iMac G5 (that shipped with Panther) and the tiger discs do not work. I get an "Alert you can not install these discs on this computer" message. I read somewhere that when you see this, a Firmware revision is in order. How do I know what Firmware I have and where to find the upgrade download? I did search, but this information is so old that it was purged from the files a few years back. Please help. Thank you.
