Apple today released Firmware Restoration CD 1.4 which can restore the firmware of an Intel-based Macintosh computer.

Note: Restoring your firmware will reset some of your computer’s preferences to defaults.

You can only use this to restore the firmware after an interrupted or unsuccessful update. If your computer is already in this state, you’ll need to download the software and create the CD on another Macintosh computer, or you can take your computer to an Apple Store or Apple Authorized Service Provider to restore your firmware. This CD can be created on either a PowerPC- or Intel-based Mac, but only works with Intel-based Macs.

Note: This CD cannot be used to return an Intel-based Macintosh computer’s firmware to a previous version if a successful update has already been performed.

Different computers use different versions of the Restoration CD. Please reference the table below to determine if this version of the Firmware Restoration CD is correct for your machine. If you do not see your computer in this table you may need Firmware Restoration CD 1.3:
