OK. I ordered two ibooks off of ebay to see which one i liked (or needed more). The blueberry ibook i have arrived today and it doesn't have an OS installed. I only have the G5 OS X install disc on DVD. Is there a way to get it to the ibook? (no firewire port on this model) The other ibook i ordered is a G3 500mhz 12 inch. (I'll probably keep this one) Which models were having the problems with the logic board?
