I have a 1.8 Power PC G5 (non intel) with OS X 10.4.11 installed. I just added ram to jack it up to 2 GB. Got my sisters family pack installation disk ( the family has only used 2 out of the 5 installs) for Leopard in the mail and wanted to upgrade to give to my kids since I have a new iMac i5. Disk keeps ejecting upon install. I get the disk install icon and when I double click it displays the "restart" (so far, so good right?) and when I restart, the disk spits out upon startup, without displaying the installer guide. I have held down the "c" button during restart.....verified the disk....verified the HD permissions......gone to Preferences to use the install disk as my start up disk. Tiger works just fine on this mac, but I would like to upgrade the OS along with the ram to get as much performance out of this unit as possible. I am having this ejection issue and am turning to anyone for help to get this installed without having to write 6000 lines of code?
