Install Software… First!
Install Mac OS Software
If you intend to upgrade your PowerBook’s Mac OS software, you
should do so first, before you run the Crescendo/WS installer application and install your Cresendo/WS card. This is especially important
if you are planning to install or upgrade Mac OS X, and you are
installing a Crescendo/WS G4 upgrade card; this will avoid certain
compatibility issues reported in some PowerBook configurations.
1. If you are installing or upgrading your Mac OS software, do so
2. After you complete the installation or upgrade process, restart
your computer.
WARNING: Before installing the Crescendo/WS processor
upgrade card, you must run the Crescendo/WS Install utility.
If you do not run the utility, your PowerBook will not operate
with the Crescendo/WS installed.
Ensure your system is booted in Mac OS 8.x or 9.x to run this utility.
Do not attempt this in Mac OS X Classic mode; this software will only
function in Mac OS 8.x through OS 9.x. Also, quit any open applications and disable any security software installed in your system.
Please note that this installer only needs to be run once, prior to the
hardware installation.

Additional Software Installation—Crescendo/WS G4
Support Note: The Crescendo/WS G4 processor upgrade
card features AltiVec (dubbed Velocity Engine™ by Apple), an
on-chip vector processing unit that greatly speeds certain operations
in AltiVec-enabled applications. To take advantage of AltiVec-enabled
applications, your system must be running Mac OS 9.0 or higher. If
your PowerBook is running Mac OS 9.1 or later, AltiVec-support is
already enabled.
The following section covers the installation of additional software
your PowerBook may require to fully support the Crescendo/WS G4
processor card. Complete the steps on the following pages after you
have successfully installed the Crescendo/WS G4 card.
Check the requirements listed below to determine which, if any, additional software you must install. If you have multiple operating systems installed, install software into the appropriate System folder for
each operating system (OS). If you have already installed Mac OS X
on your system, be sure to also read the important information on
page 10 regarding updating your Mac OS X software.
• Mac OS 8.1–8.6: No additional software installation is required; you
may skip this section if OS 8.1–8.6 is your system’s only OS.
• Mac OS 9.0.x: You must rerun the Mac OS 9 install application to
install AltiVec libraries into your System Folder (instructions follow).
