Description: This software installs the Sonnet Firmware Updater and Sonnet Firmware Remover applications to your computer's Mac OS X Applications folder. Sonnet Firmware Updater installs the firmware patch necessary to support various Encore/ST processor upgrade cards. Version 3.2 adds support for use in computers running versions of Mac OS X Version 10.5.
Computers: Power Mac G4 (all models except PCI Graphics).
Note: Users running Mac OS X Version 10.4 or 10.3 should use version 3.1 of Encore Firmware Updater Installer (Mac OS X).
When installed correctly, the Encore/ST G4 card reusing the Apple heat sink is just as reliable as the more recent Encore/ST G4 card with a pre-attached Sonnet heat sink. Sonnet chose to pre-attach a heat sink to Encore/ST G4 upgrades (except for those with a part number that starts with SG4-C) because we determined that some users did not properly attach the Apple heat sink and clips, and we wanted to make the installation process easier.
