1) Can I boot a separate system off of a FireWire hard drive? I have two partitions (Bootcamp OSX/Vista) on my MacBook Pro, but can't really spare any space for a new (linux) partition. 2) If it is possible to boot, how does this affect daisy chaining of FW800s. 3) How does daisy chaining work, anyhow? Is it possible to set up Time Machine for both so that it will automatically keep the data backed up on both (for the sake of redundant storage)? 4) Somewhat OT: Can you boot from a Expresscard 34 SSD?
