| 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. |

| After installing my new Crescendo/PCI processor upgrade in a Power Tower Pro, I can hear the boot chime when I turn the computer on, but the video display never comes up. | May-12-09 |
| 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.
You can identify the problematic motherboard by the part number. The part number is "silkscreened" onto the motherboard in white ink, like all the other markings on the board, and is located along the edge of the motherboard when you open the case and look directly at it (see below). The part number on the problematic system is PCC-5000-0141-01.
Sonnet has been unable to resolve this issue; Crescendo/PCI processor upgrade cards are incompatible in this one, specific instance. If you already purchased a Crescendo/PCI card and your computer has the motherboard described, return the product to the place you purchased the card and request a refund.
