This article has been archived and is no longer updated by Apple.

This article contains the About iBook Firmware Update 4.1.7 document and links to the iBook Firmware Update 4.1.7.

The iBook Firmware Update 4.1.7 will only run on iBook computers running Mac OS 9.1 from a local drive. If you are using Mac OS X you must boot from a local Mac OS 9.1 writeable partition (not a CD, or network disk) prior to following the update instructions.

Firmware update 4.1.7 is also available for iMac computers with slot-loading CD or DVD drives. Firmware update 4.1.8 is also available for PowerBooks with built-in FireWire ports, Power Mac G4 Cube and Power Mac G4 models.

Firmware Update 4.1.7 includes improvements to Firewire target disk mode, network booting, gigabit networking (on systems with gigabit hardware), and system stability. This update also adds support for additional security options which allow the Open Firmware to be password protected.

This update also contains changes from earlier Firmware Updates. This update adds support for 256 megabytes (MB) memory modules and improved support for using a USB storage device, such as an external hard drive, as a startup disk.

Before you install iBook Firmware Update 4.1.7, 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. Make sure your iBook computer's power cord is connected and plugged into a working power source.
  2. Double-click the iBook Firmware Updater icon.
  3. Note: If a message says your firmware is up-to-date with version 4.1.7 of the iBook Firmware Updater, or that this version of the iBook 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 9.1, the firmware updater will not run until you install Mac OS 9.1 or later.

  4. Follow the onscreen instructions. When prompted, click Shut Down in the dialog box to shut down your iBook.
  5. After the computer has shut down, hold down the Command (Apple) key and Power button to start up your iBook.
  6. Continue to hold down the Command key and Power button until you hear a long tone. Release the Command key and Power button when you hear the tone. The update starts automatically.

A status bar shows the progress of the update. When a message says your computer's firmware has been successfully updated to version 4.1.7, you are finished.

Note: If a message says the update was not completed successfully, review the instructions and begin the update process again.
