| Will my Crescendo/WS upgrade recognize any DIMM? | May-12-09 |
| The Crescendo/WS will work with any DIMM that works with the "stock" Wall Street PowerBook, and in many cases increases available memory from 192MB to 512MB. This is due to the resolution of an Apple ROM issue that prevented some of these systems from properly recognizing all available RAM.
There are some 256MB modules that can only be utilized as 128MB, due to a limitation of the parts used at the time that these notebooks were manufactured. A controller chip used in the system's design can recognize a maximum of 128MB of RAM in each "bank" of memory. Until recently, virtually alll 256MB DIMMs used two banks of 128MB. Recent advances in RAM have led to the introduction of some DIMMs with 256MB in a single bank, which has raised the visibility of this issue. These parts are stable, and are not known to reduce system reliability, but they will not deliver the full desired memory capacity. There is no single method for identifying these parts without installing them, so it is recommended that you work with a reseller who can either confirm the design, or who will accept a return based on compatibility. |

| When I insert a diskette into my PowerBook it does not mount to the desktop. | May-12-09 |
| This issue occurs when a diskette is formatted with PC support. The diskette becomes unmountable while the "Sonnet Processor Upgrade" extension is running on a PowerBook 1400, 1400c/117, 1400cs/117, 1400c/133, 1400cs/133, 1400c/166, and the 1400cs/166.
If there is a need to mount a PC-formatted floppy disk after upgrading your PowerBook 1400 series Macintosh, the "Sonnet Processor Upgrade" extension must be turned off. To do this, simply open up the Extension Manager Control Panel and scroll down to the beginning of the Extensions list. The "Sonnet Processor Upgrade" extension should be one of the first couple of extensions in the list. Once the extension has been located, click the checked box next to it to deselect it. Once the computer is restarted, the Sonnet extension will be turned off and a PC-formatted floppy will mount. If there is a regular need to mount PC-formatted floppies, you can eliminate a step from this process by creating an alternate set of extensions in which the "Sonnet Processor Upgrade" extension is turned off.
Note: When running the computer with the "Sonnet Processor Upgrade" extension off, the processor will still be running at its rated speed, but the L2 cache will be disabled.

| PowerBook crashes when Sonnet Crescendo/Encore software extension is active. | May-12-09 |

| PowerBook G3 with a Crescendo/WS installed has unstable operation, including slow and erratic operation of applications, and possible machine freeze-up.
| Jun-17-09 |
| Installation of certain combinations of DIMMs (RAM) of different capacities on the Crescendo/WS processor upgrade card may result in unstable operation of the PowerBook.
This issue affects Crescendo/WS cards manufactured before February 12, 2002. These parts may be identified by serial number, ranging from A1001 to A1949. The serial number is printed on a white sticker, and is affixed to the bottom surface of the card. Crescendo/WS cards manufactured February 12, 2002 and after are not affected by this issue, and have serial numbers of A1950 and higher.
Users who encounter this issue should download and run the Crescendo/WS firmware updater.
Note: As it is necessary to open your PowerBook to check the serial number on the Crescendo/WS processor card, you may save time by downloading and running the firmware updater; if your card's firmware is already up to date, no update will take place.
This Sonnet firmware update adjusts specific logic memory timing parameters on the Crescendo/WS processor upgrade card and fixes operational instability of PowerBook G3 Series machines with the Crescendo/WS G3 card installed.
This firmware update also boosts the maximum supported memory on the Crescendo/WS from 192MB to 512MB, far exceeding Apple Computer's stated maximum capacity for these systems. |
