Many years ago I was bequeathed an eMac. I believe it's a 1 GHz G4. It's been sitting around doing nothing for a long time, but now I need to install realMYST Mac edition, from 2002, and it's my best bet.
I was given three OS X install discs with the eMac: A 10.0 disc, an eMac Software Restore disc (that says it has Panther on it), and also a set of Panther upgrade discs. Unfortunately, the eMac refuses to boot from either the 10.0 disc or the Restore disc. It will boot from the Panther Upgrade disc, but I can't install it because the hard drive is blank and doesn't have a previous version of OS X on it!
Is there some file on the disc I could delete, some plist I could change or something, to make this installer not do the upgrade check? Or does anyone have any ideas on how to get it to boot from the restore disc?
EDIT to clarify:
The discs that the eMac won't boot from are in perfect condition and entirely readable by other Macs; the eMac simply won't boot from them. But it boots perfectly every single time from the Panther Upgrade disc. And the Panther Upgrade disc is way more scratched up (to the naked eye, anyway) than the others.
Apparently this eMac shipped with OS X 10.3 Panther. The restore discs claim to have Panther on them. But the eMac won't boot from the restore disc, even though it boots from the Panther Upgrade disc.
