I am in the process of fixing a friends 900Mhz iBook whose internal ethernet adapter has aparently come loose from the main logic board. The solder joints broke. I am pretty handy with a soldering iron, so I am confident that I can fix it (the warenty is already expired), but my question is how do I go about taking the computer apart with the minimal disasembly possible to fix just that part. I don't want to have to have the entire computer in bits if I don't have to. I have an article printed on installing a new HD, so I already have a "general dissasembly guide", but I only need access to the top-left corner of the logic board.
