I was wondering how to copy a Tiger .dmg file to multiple CDs. You know, since it doesnt fit on one CD. I need to install it on my iMac G3, but it doesn't read DVDs. Is there any way to do this?
iMac, Mac OS 8.6 or Earlier
Hi, I don't think anybody has ever done it, nor do I think there's a way to make it work, that being said there was a rare 4 CD version offered by Apple for a short time for people in your position.
You could try 'restoring' it to a hard disk or other external drive. If you have a suitable drive you may be able to boot from that. Firewire should work if you have the connector.
Disk Utility can restore one volume to another (in the restore tab), select your Tiger DVD & try that on a Mac that can read the DVD. Do you really have .dmgs? dmg's will need 'scanning for restore' before they can be copied to another disk. The destination will be erased. It will probably need to Apple Partition map format too.
Another option is to hack (or delete) the installer packages to reduce disk the size. If you avoid installing all the extra apps you may be able to make a disk that can get the base system installed but that will require lots of testing since the installer will want to use most packages by default.
I vaguely remember there were tools to make bootable OS X CD's, but I can't remember if it was Dasboot, BootCD or some other app, sorry.
