Thank you Jacob and Scott! I am reassured knowing I can install thru firewire from the iMac. When the time comes, I may be asking for more advice once I am actually doing it hands on... Hope to get Leopard for Christmas. :-) On Nov 11, 2007, at 7:31 AM, Jacob Ritorto wrote: Suzanna, I've found it quite easy to install onto titaniums with no disc. You connect your mac with the working disc to the one with the broken disc using the firewire cable, then power on the broken one while holding down t (or maybe apple-t, I forget offhand). This puts it into firewire target mode. I know it's in that mode on mine when the screen comes up blue with a yellow symbol. Once that's done, power on the machine with the working disc (and your Leopard install dvd inserted) while holding down c. Once the good machine boots from the install disc, it will see that there's more than one place to install to and will allow you to chose where to install. I think the firewire target machine (your broken-disc titanium) shows up in the list of choices as a symbol that looks like the yellow symbol displayed on the broken machine's screen. Select that and run the install as normal. When it's all done, you can boot the good machine as usual, but the broken-disc machine has a newly installed OS. Just make certain you're not selecting the normal drive on your good machine to install to. I've only done fresh installs to the target and have never tried to preserve the contents of the target machine during this operation, so I don't know if there's a way to keep installed programs, etc on the target, so you're on your own if you need to preserve stuff on the broken-disc machine. Maybe if you select 'archive and install' it'll keep stuff for you.. dunno..
