![]() Consult your computer's documentation for the location of the L2 cache. There are some models where the L2 cache card is inconveniently located, and in some cases, it is soldered to the motherboard and cannot be removed. If the card has been in place for years, it may be difficult to extract, and care should be used to gently work the card out. In these configurations, there are no clips holding the card in place, so it should lift straight up and out of the machine. In most cases, it is clearly identified by markings on the motherboard, and its socket is offset from the others. In most Mac and Mac clone models, the L2 cache card is similar in appearance to a DIMM, and is usually located amongst or near the memory (DIMM) sockets. Important Note: Be sure to take all precautions against static discharge during this process, or you may inflict permanent damage to part, or all of your computer. There is no loss of performance or any other benefits when the original L2 cache card is removed. Since the Crescendo/PCI has its own L2 cache, the computer's L2 cache is deactivated once the processor upgrade is installed. To fix this issue, remove the computer's L2 cache card. The computer's original Level 2 (L2) cache conflicts with that on the Crescendo/PCI card. Hang or crash occurs before desktop appears. 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. Otherwise, go to step 2.Ģ) Restart the computer under Mac OS 9 with extensions off (hold down the Shift key when you turn on the computer until the message "Extensions Off" appears).ģ) Launch the Crescendo/Encore Installer from the desktop and follow the instructions. Under certain conditions, the Crescendo/Encore Installer application encounters conflicts that cause it to hang, or even crash the computer when the computer is booted in Mac OS 9 with extensions on.ġ) If you have attempted to run the application directly from the Sonnet Installer CD, copy the Crescendo/Enc Ins file from the CD to the desktop (single-click and drag the file from the Mac OS 7-9 ONLY, not CLASSIC folder on to the desktop). The Crescendo/Encore installer hangs, or crashes the system occurs most often when run from the Sonnet installer CD while using Mac OS 9. 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. May I discard my original CPU after installing Sonnet's upgrade cards? Unfortunately, Sonnet cannot provide support for this modification, although the Crescendo/PCI G4 800 (and 700) will operate with it. There is a web site, which provides tools to do this for Mac OS 9.2.1 and 9.2.2. It turns out that it is possible to add these sections of system software back in, and create a hybrid Mac OS 9.2 that will run with the 9500 family and the Crescendo/PCI G4 800 and 700. To accomplish this, they removed some specific parts of the operating system software that enabled operation on the Power Macintosh 9500 family and earlier machines beige Power Macintosh G3 models are the oldest systems still supported under Mac OS 9.2. When Apple created Mac OS 9.2, they decided to limit the number of machines supported to make the testing and qualification job easier. Why can't I run Mac OS 9.2 on my computer upgraded with a Crescendo/PCI G4 800 (or 700)? What are the known incompatibilities with the Crescendo/PCI G4 700 and 800?

It will likely work on most other amd64 machines too, but it does not contain UEFI boot files that some people need.
