I was installing Tiger using FireWire from my Powermac G4 and it was nearly done when my Powerbook (target) died due to lack of battery... When the Powermac was rebooted, I get only a question mark and flashing smile... I tried to test the C and T keys holding them down during boot up but only get the smiley face every single time... I even disconnected the secondary drive to no avail! What happened?
