I have an imac g4 with a cdrw drive. Is it possible to connect a external combo drive via firewire or usb to be able to load the new OS or other programs? or do I have to take the thing apart and replace the drive?

Yes you should be able to firewire boot, but not USB. hold down the option (alt) key when you power up with the install CD in the external drive. It will take a couple of minutes but then show you the bootable drives. Click on the one you want then on the 'go' icon.

has anyone booted from a combo external drive before? is it some what simple to replace the drive myself to a combo drive?
