Last weekend I had the pleasure (!) to install Tiger on an ancient PowerMac that doesn’t feature any DVD-ROM drive. I don’t happen to have the special CD-version of 10.4 and trying to boot from an external DVD drive somehow failed. However, this Mac already had Firewire, so here is a little hint on how to install Tiger using a spare Firewire drive:
$ fink install psync
Format the Firewire drive with HFS Extended. You don’t need Journaling, so please disable it.
Now, assuming you’re Tiger Install DVD is mounted at /Volumes/Mac OS X Install DVD and your formatted volume is mounted at /Volumes/OSX, type this into your Terminal to clone the content of the DVD over to the harddrive.
$ sudo psync -d "/Volumes/Mac OS X Install DVD/" /Volumes/OSX
Finally make the whole copy bootable by blessing it:
$ sudo bless --folder "/Volumes/OSX/System/Library/CoreServices" --bootinfo
Now, you may unmount and install. Fin .
