Hello, All of a sudden, on my Intel Imac 2.0 ghz..(first generation of the intel version of imac) running Tiger 10.4.11 .. I have no firewire ports .. ( the 2 firewire 400 ports do not see any of my various external firewire drive, nor my video camera via firewire.. I have tried replacing all the cables, repaired permission of the system drive .. power down, reboot etc.. Anyone have any suggestions?? Thank You Mike M.
