About the Power Mac G4 Firmware Update 2.4

The Power Mac G4 Firmware Update 2.4 will only run on Power Mac G4 models with AGP graphics using Mac OS 9.0 or later.

Firmware updates are also available for iBooks, iMac computers with slot-loading CD or DVD drives, and PowerBooks with built-in FireWire ports.

The Power Mac G4 Firmware Update 2.4 fixes a startup problem with some third-party memory modules and a problem recognizing when more than one gigabyte of memory is installed. On some early Power Mac G4 models, this update also allows a USB or FireWire storage device such as an external hard drive to be used as a startup disk.

Before you install the Power Mac G4 Firmware Update 2.4, read the instructions below. You may want to print them for reference.

Note : After you install this update, the PRAM is reset. This may reset some of your control panels to default settings. See Mac Help, available in the Help menu, for more information on changing your control panel settings.

1. Double-click the Power Mac G4 Firmware Updater icon.
Note : If a message says your firmware is up-to-date with version 2.4 of the Power Mac G4 Firmware Updater, or that this version of the Power Mac G4 Firmware Updater will not run on this computer, then you do not need this update. If a message says you need to install Mac OS 9.0, the firmware updater will not run until you install Mac OS 9.0 or later.

2. Follow the onscreen instructions. When prompted click Shut Down in the dialog box to shut down your Power Mac G4.

3. Locate the programmer's button on the front of the Power Mac G4, to the right of the reset button. Press and hold in the programmer's button. You may need to use a pen or a straightened paper clip.




4. While you hold in the programmer's button, press the Power button to start up your Power Mac G4.

5. Continue to hold in the programmer's button until you hear a long tone. Release the programmer's button when you hear the tone. The update starts automatically.
