169 May I discard my original CPU after installing Sonnet's upgrade cards? May-07-09

175 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
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.

To solve this issue, follow these steps:

1) 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). Otherwise, go to step 2.

2) 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).

3) Launch the Crescendo/Encore Installer from the desktop and follow the instructions.
 
176 Sonnet OS X Installer InstructionsMay-07-09
MAC OS X USERS -- Install Sonnet Firmware Patch
This section describes the installation of software required to support the Encore ZIF, Encore ST, or ST Duet G4 in your computer. Please note you MUST run the Sonnet Firmware Updater before you install this upgrade card. If you do not run the updater, your computer will not operate with the processor upgrade installed.

1) Insert the Sonnet Installer CD into the CD-ROM drive. Double-click the Sonnet Install CD icon. When the Sonnet Install CD window appears, double-click the Mac OS X ONLY folder.

2) Double-click the Sonnet Firmware Updater icon; Mac OS X's built-in Install program will launch. Follow the onscreen directions to complete the installation of the Sonnet Firmware Updater and Sonnet Firmware Remover applications to your Applications folder.

3) Shut down your computer.

4) Press and hold the programmer's button until you hear a long tone; release the button when you hear the tone. Note: programmer's button is the little tiny pinhole on the front of a Quicksilver.
4a. For QuickSilver 2002: While holding the programmer's button, press and hold the 'start-up' button on the front of the Mac. When the Mac starts up, release the start-up button. Continue to hold the programmer's button and when you hear a long tone, release it.

5) Once the startup process is complete and you have logged in (if necessary), go to the Finder and select Applications from the Go menu.

6) Locate Sonnet Firmware Updater, and then double-click its icon to launch the application.

7) When the Sonnet Firmware Updater window appears, click OK.

8) When the Authenticate window appears, enter the Administrator password, and then click OK.

9) When the Wait message appears, DO NOT CLICK OK; just wait. Clicking the OK button will cause the application to quit. After the Wait message disappears, another message will appear indicating that the ROM is being patched. Do not turn the power off; this process may take several minutes.

10) When the message stating that the ROM has been patched appears, click OK. Shut down your computer; you may now install the Encore ZIF, Encore ST or ST Duet processor upgrade card.

Note: After updating your system's firmware with the Sonnet firmware installer, you do not need to install the other software located in the Mac OS X ONLY folder on the Sonnet Installer CD; that software is used for other processor upgrade cards by Sonnet.
