The only two CD's in that collection that "might" boot that machine is the 8.0 and 10.2.1 Cd's.
Given that you have the original 8.0 disks, this machine must be pushing retirement age. You did not mention what PowerMac it was nor what OS you were running at the time of the crash.
First, try this. Disconnect BOTH HD's. Put in the 8.0 disk and try to boot from the CD.
If it boots, add ONE HD back. Try again.
If successful, add the second, if not, change out and use the other disk.
If that fails, repeat with the 10.2 disk.
These drives could be SCSI, depending on the age of the machine, but that should not present a problem.
The Mac Power PC had a drive error, and now won't boot. I have the Original 8.0 CD, the Upgrade 8.5 9.2.2 and 10.2.1 CDs. NONE will run and boot the machine using either the 'c' or the 'OPT-CMD-SHIFT-DEL' tricks, and I do not have a 'install' floppy. The unit has two 4.3 Gig HDDs. HALLLLP. Only other machine is a PC.
Thanks Much, John Jewkes
