| What are the known incompatibilities with the Crescendo/PCI G4 700 and 800? | May-12-09 |
| While this new G4 upgrade supports virtually all clones, some PowerTower Pros have a second, very different motherboard design. The problematic version of the motherboard appears to be very rare, based on Sonnet's sales history and the number of related calls. Nevertheless, the Crescendo/PCI G4 700 and 800 are not currently compatible with this version. You can read the entire description, complete with diagram, at:

Regarding PCI video cards, most of the Power Computing clones, as well as a couple of the Apple PowerPCs do not have onboard video, and may have come with certain cards (IX Micro Twin Turbo, IX Micro Ultimate Rez, ATI XClaim 3D, and the ATI Mach 64) installed that are not compatible. These cards are legacy video cards and have not had software or firmware updates in several years. The lack of updated software/firmware, combined with the technology of the G4 chips used in these processor upgrades, results in various video anomalies. Because the problems reside in these cards' drivers, a resolution is not expected, and an alternative video solution is required. Recommended cards compatible with these processor upgrade cards include the ATI Radeon 7000 Mac edition. |

| Why can't I run Mac OS 9.2 on my computer upgraded with a Crescendo/PCI G4 800 (or 700)? | May-12-09 |
| When Apple created Mac OS 9.2, they decided to limit the number of machines supported to make the testing and qualification job easier. 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.
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. There is a web site, www.os9forever.com, which provides tools to do this for Mac OS 9.2.1 and 9.2.2. Unfortunately, Sonnet cannot provide support for this modification, although the Crescendo/PCI G4 800 (and 700) will operate with it. |

| The Crescendo/Encore installer hangs, or crashes the system; occurs most often when run from the Sonnet installer CD while using Mac OS 9. | 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 |

| System will not finish start-up process. Hang or crash occurs before desktop appears. | Jun-23-09 |
| The computer's original Level 2 (L2) cache conflicts with that on the Crescendo/PCI card.
To fix this issue, remove the computer's L2 cache card. Since the Crescendo/PCI has its own L2 cache, the computer's L2 cache is deactivated once the processor upgrade is installed. There is no loss of performance or any other benefits when the original L2 cache card is removed.
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.
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. In most cases, it is clearly identified by markings on the motherboard, and its socket is offset from the others. In these configurations, there are no clips holding the card in place, so it should lift straight up and out of the machine. 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.
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. Consult your computer's documentation for the location of the L2 cache. If it is soldered on, contact Sonnet's customer service at 1-949-472-2772 for further instructions. |
