||May I discard my original CPU after installing Sonnet's upgrade cards?
||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|

||Mac OS 10.5 "Leopard" shuts down a few seconds into booting after a new installation of the OS.||May-07-09|
|This problem has nothing to do with our processor upgrade being in the machine or with the firmware update that was done beforehand.|
It has everything to do with how 10.5 was installed. Doing the 10.5 install as a simple "Upgrade" rather than using some of the other options like Archive and Install or Erase and Install.
When you do a straight upgrade, the installer just overwrites the old 10.4 System folder and that can leave some incompatible kernel extensions lurking in the new 10.5 folder whose response to that is to shut down on boot if it encounters something it doesn't like. So you need to do an Archive and Install of 10.5. This will create a new System folder, migrate your various user settings but it won't migrate any outdated stuff to the new folder.
||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.
