I have an USB dual ibook 500 mg. the optical drive is gone. I need to re- install os x 10.4. the hard drive is 10 gig and is empty right now. i had it installed previously. I hear maybe i can use a firewire ...etc. Any good explicit instructions out there. I have also heard that it cannot be done.. with my ibook model. HELP!!!!!!! thanks so much Janice F.
