From a Mac service tech (well part time one giggle) Resetting PRAM and NVRAM on Power Macintosh, iMac, and iBook Computers 1. Shut down the computer. 2. Locate the following keys on your keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 3. 3. Press the Power button, then hold down the Command-Option-P-R key combination. You must press this key combination before the gray screen appears. 4. Hold the keys down until the Macintosh restarts itself twice. 5. Release the keys after the Macintosh restarts twice. 6. The parameter RAM and the non-volatile RAM in your computer is reset to the default values. The clock setting are not changed. Resetting PRAM on PowerBook computers Resetting, or zapping, the Parameter RAM (PRAM) when the computer is shut down also resets the power manager. For a description of how to reset the power manager and PRAM in your PowerBook, refer to the following Knowledge Base article: Article 14449: ' PowerBook: Resetting Power Manager.' Resetting PRAM on Non-PCI Power Macintosh Computers System 6.x 1. While opening up the Control Panel, hold down the Command, Option and Shift keys. 2.
