Hey guys-- so the superdrive in my 1ghz 1gigoram 15" tibook never worked-- and apple finally figured out it was the logic board, replaced it, and the superdrive works now, but everything seemed slowed... Well-- today I noticed that my tibook is now running at 867mhz!?!? Any idea on how to correct this without sending my 'book back? :( -- Samuel W.
