Ok, I need a DVD-ROM drive to install Tiger on my iBook. I would rather go with a Firewire external enclosure for hdd and cd/dvd than have to buy two separate things. But can you boot off of an enclosure via Firewire? or do I have to find a Mac compatible DVD-ROM external Drive and do it that way?. Thanx this will help me figure out what to buy Friday at Comp or Staples or off the internet.
