Install Sonnet Software
Before proceeding with the hardware installation, you must run the
Crescendo/WS Installer. Otherwise, your PowerBook will not operate with the
Crescendo/WS installed.
1. Insert the Sonnet Installer CD into your computer’s CD-ROM drive. Double-
click the Crescendo/WS Installer icon to start the utility.
2. Click the Install button to start the software installation; the process takes just
a few seconds.
3. After the software installation is complete, click the Shut Down button to
shut down your computer.
Shut Down and Open Computer
1. If you have not already done so, shut down your PowerBook. If the comput-
er has been on for any length of time, wait a couple of minutes for it to cool
before beginning the installation.
2. Disconnect all cables from your PowerBook, including the power cable. If
necessary, move your PowerBook to an area with a flat, level surface where
you can freely work.
3. Open the display on your PowerBook to a 90˚ angle; you must do this to
prevent it from tipping over during the installation process (Figure 1).
4. Locate the expansion bay release levers on the front edge of the computer
(Figure 2), then pull them out to eject and remove batteries and modules
installed in both expansion bays.
5. Reach inside the expansion bays to locate the two small, ridged plastic tabs;
these are the keyboard release levers. Slide the levers toward you until the
lower edge of the keyboard rises (Figure 3).
6. Lift up the lower edge of the keyboard slightly, and pull it toward you until
the tabs on the upper edge of the keyboard are visible (Figure 4).
7. Gently flip the keyboard over on top of the palm rest and trackpad
(Figure 5).
Quick Start Guide for Crescendo/WS
Support Note: Before proceeding with the software installation,
ensure your system is NOT booted in Mac OS X, nor Mac OS X Classic
mode; the Crescendo/WS Installer will only function in Mac OS 8 through
OS 9.x. Quit any open applications and disable any security software installed in
your system.

Remove Heat Sink Plate
1. Touch the metal surface of the hard drive to discharge static from your body
(Figure 6).
2. Remove the two screws securing the internal heat sink plate (Figure 7).
3. Pull up on the attached handle and remove the heat sink plate (Figure 8).
Remove Processor Card
1. While holding down your PowerBook with one hand, insert the hook end
of the processor card removal tool under the bottom right corner of the
processor card, then gently and slowly pull straight up on the edge of the card
to disengage it from the logic board (Figure 9). Do not attempt to pry out the
processor card; you may damage the card or the hard drive.
2. Grasping the processor card by its right edge and the edge of its RAM slot,
move the card to the right to disengage its tabs from the processor card
shield (Figure 10). Carefully lift the card up and away from the logic board.
Support Note: To avoid regenerating a static charge in your body, do
not walk around the room until after you finish the installation, reassem-
ble and close the computer.

Move RAM (Memory) From Processor Card to Crescendo/WS
Depending on the configuration of your PowerBook, your processor card may
have RAM modules installed on both sides of the processor card.
1. Turn the processor card over so the two connectors are face up (Figure 11).
Grasping the processor card by its edges, gently spread apart the retainer clips
on both sides of the RAM module (Figure 11); the module will pop up.
Remove the module and set it aside on a static-free surface.
2. Remove the Crescendo/WS (Figure 12) from its anti-static package, making
sure to handle the card by its edges.
3. Turn the Crescendo/WS over, so that the two connectors are face up
(Figure 13). Align the RAM module removed from the bottom of the origi-
nal processor card with the RAM slot on the Crescendo/WS, and insert it at a
30˚ angle, all the way into the slot (Figure 13).
4. Gently push down on the RAM module until the retainer clips snap into
place (Figure 14).
5. If there is a second RAM module installed on the processor card, remove it,
then install it on the Crescendo/WS card following the same procedure as for
the first RAM module.
6. Place the original processor card in the Crescendo card’s anti-static bag, and
store it in a safe place.
Install the Crescendo/WS
1. Turn the Crescendo/WS so that the connectors are face down, and the tabs
on the edge of the card are facing left (Figure 15). Grasping the card by its
right edge and the edge of its RAM slot, carefully insert the tabs into the
processor card shield and align the connectors on the bottom of the card
with the corresponding connectors on the logic board (Figure 15).

Support Note: Do not touch the RAM modules’ connectors; always
handle RAM only by its edges.
Support Note: If you are installing two RAM modules into the
Crescendo/WS card, be sure to install them into the expansion slots that
correspond to those on the original processor card. When you install RAM, note
that the modules are designed to fit into the slot only one way; align the notch
in the module to the guide in the slot.

Reinstall Heat Sink Plate
1. Insert the tabs on the edge of the heat sink plate into the PowerBook, then
lay the plate flat (Figure 17).
2. Gently press down on the lower section of the heat sink plate, then secure
the plate with its two screws (Figure 18). Do not overtighten the screws.
Reassemble Computer
1. Flip the keyboard over, and insert the tabs at the top of the keyboard into the
slots in the PowerBook case (Figure 19). Press down on the keyboard until it
snaps into place.
2. Install the battery and expansion module(s) back into the expansion bays
(Figure 20).
3. Connect the power cable to the PowerBook, but leave other cables discon-
nected for now.
4. Affix the Powered by Sonnet label to your computer.
Turn On Computer
1. Press the Power button on your PowerBook. You will not hear the normal start-
up sound, but instead a long tone; the display will remain blank.
2. During the next 30 to 45 seconds, the hard drive will spin up and you will
hear eight tones.
3. Your PowerBook will restart. Your accelerated machine should boot normally.
If you have just installed a Crescendo/WS G3 card, or if Mac OS 9.1 or later is
already installed on your system, your PowerBook is ready to use and your installa-
tion is complete. Otherwise, continue to page 6.
