Apple has released the Power Mac G4 Firmware Update 4.2.8.

This firmware update only runs on Power Mac G4 and Macintosh Server G4 models with AGP graphics running Mac OS 9.1 or later from a local hard disk. However, if Mac OS X is installed start-up must be in Mac OS 9.1.

This is a North-American English update. Improvements include starting up from the local hard disk, FireWire target disk mode, network start-up, gigabit networking (on systems with gigabit hardware), and system stability.

This update has support for additional security options that allow the Open Firmware to be password-protected.
