Subject: RE: Tech: Optical drive on Mac - and other bits
The G4 iMac I have may have been altered already by fitting a CDrom drive. I inadvertently downgraded it further by installing an unidentified backup copy of the OS X (on two CDs) which took it from 10.3 to 10.2 . I don't think the DVD (official) OS X 10.4 I have would clone onto a single CD. (I haven't tried booting from an external firewire DVD reader yet, but I've got a feeling that that route is blocked by the firmware requirement I mentioned above.) The other 10.4 official two-CD versions I have are for specific machines (G4 tower, Mac Mini) and will not boot on the iMac. There is a 16-CD (sic!) version for eMacs that I haven't tried yet - I'll let you know.

There is another way of getting OS X 10.4 onto the iMac hard drive if you have another machine with the appropriate OS installed. SuperDuper or CarbonCopyCloner (and possibly the program Richard mentioned) can produce a clone of the source machine's HD. The receiving machine has to be set up in Firewire "Target" mode and is then treated as an external HD during the copying process. Both programs are available as free downloads if use is restricted to cloning. They have further backup facilities for which a contribution is requested.
