I have an old red iMac (all-in-one model) running on OS9.??? purchased around 2000. I'm sorry I can't be more specific, but it won't start, and I don't have any of the original info or software CDs (lost long ago). I was just using it for internet access for the kids, and now all I get is the flashing question mark when booting. A friend who lost a similar iMac in Katrina game me a set of OS9.0 "software install" and "software restore" CDs, and I tried booting while holding down the "c" on the keyboard, but I still only get the flashing question mark. The CDs say "For iMac DV models" My question is, should I be able to start my iMac from these CDs? Or is there an incompatability problem since they came from a different computer. All I need is to get the darn thing started because I know there's nothing wrong with it. Thanks.
