| The speed indicated on the G3 or G4 chip on my Sonnet processor upgrade doesn't seem to match the speed of the upgrade I purchased. What's the story? | May-07-09 |

| The computer's standard startup process takes noticeably longer after upgrading to any Mac OS 9.x system from Mac OS 8.6 or earlier. | May-12-09 |
| This is not a malfunction and is not related in any way to Sonnet upgrade products; this is the result of an additional Mac OS 9.x startup process that did not occur during startup in earlier Mac OS versions. There is a new "hidden" Mac OS 9.x feature called Startup Memory Tests in the Memory Control Panel, which defaults to the "On" setting. This adds time during a startup or restart, as all of the RAM installed in the computer is checked.
This issue affects any machine running OS 9.x (OS X status is unknown as of this writing), with or without upgrades installed. The more RAM installed, the longer the test. (Note that a Mac upgraded with a Sonnet G3 or G4 processor card gets through this process much faster than a "stock" machine.)
Since this is not a malfunction, no solution is required. However, since RAM seldom fails after the first few days of regular use, you may turn this test off if a faster startup cycle is desired. To access this feature you must hold down the Command key and the Option key WHILE opening the Memory Control Panel. When the control panel opens, you will see a setting at the bottom of the control panel. Click the Startup Memory Tests' Off button, then close the Memory Control Panel. Be aware that from now on, when you start up or restart your computer, the Mac OS will NOT check your RAM. If in the future you suspect a memory problem and want to check your RAM, you will need to repeat this procedure and turn the Startup Memory Tests back on. |

| The FireWire port on HARMONi-upgraded iMac computers is disabled. Also, Apple System Profiler reports machine speed as "66 MHz" after installation. | Jun-24-09 |
| 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. |

| Although the installed processor upgrade card works properly, devices connected to the FireWire port of the HARMONi upgrade cannot be used. | Jun-24-09 |
| 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. |
