Some HARMONi units were shipped with the Sonnet Installer CD, which is labeled Software for Crescendo/WS G3 Processor Upgrade Cards Version 1.0; this Installer does not enable the FireWire port. This Installer does properly enable the processor, but Apple System Profiler will not report the correct speed.

Note: Users who received the Sonnet Installer CD labeled Software for Crescendo/WS G3 and HARMONi G3 Processor Upgrade Cards Version 1.0 are not affected.

Users who encounter this issue should download and run the HARMONi Updater.

This Sonnet firmware update enables the FireWire port on affected HARMONi upgrades, and fixes the incorrect reporting of machine speed in Apple System Profiler.

Issue 1: Driver software is required for FireWire support under every version of Mac OS; without the necessary drivers installed in your system, FireWire devices can't be used. If your system is running Mac OS prior to version 9.2.x, Mac OS FireWire driver software must usually be installed separately.

Issue 2: Many devices require additional drivers and application software to operate or have full functionality.

Solution for Issue 1: If your iMac is running Mac OS 8.6 or 9.0.x, you must download and install the necessary drivers; click here and choose the appropriate software. If you installed Mac OS 9.1 prior to installing the HARMONi upgrade, you must run the Mac OS 9.1 Install or Upgrade application again to install the Mac OS FireWire drivers. Refer to the Quick Start Guide included with your HARMONi upgrade for detailed instructions.

Solution for Issue 2: Install the device-specific FireWire driver. Software should have been included with the device, or should be available to download from the manufacturer's web site. Check the device's user guide for information about necessary software.
