Upgrading to Mac ® OS 9.x and a G4
This chapter contains instructions for installing Mac
OS and application software that adds libraries and
extensions to use AltiVec instructions for
Crescendo/ PCI G4 processor upgrade cards.
Upgrading to AltiVec-Enhanced Software
Mac OS 9.x
Mac OS 9 is the earliest Macintosh ® operating system
to include AltiVec libraries. The Crescendo/PCI
G4 fully supports AltiVec-enhanced software. To
correctly install the AltiVec libraries, make sure you
perform the installation upgrade in the following
order (if you have already installed Mac OS 9.x, the
Sonnet software, and the Crescendo/PCI G4
processor upgrade card, skip to step 4).
1. Install Mac OS 9.x
Sonnet recommends a Clean/Universal install of
the Mac OS. Start up your computer from the
Mac OS CD and double click the Mac OS Install
application. In the Select Destination window, click
the Options button and click the Perform Clean
Installation checkbox that appears in the
subsequent screen. Click the Select button.
Proceed through the next several screens until
you reach the Install Software window. Click the
Customize button. In the Custom Installation and
Removal window click the pop-up menu to the
right of Mac OS 9.x. Change the “Recommended
Installation” to “Customized installation.” The
Select Mac OS 9.x Features to Install window will
appear shortly. Change “Recommended
Installation” to “Universal Installation” from the
pop-up menu. Click OK, Start, then Continue to
complete the installation. After the software is
installed, quit the Mac OS Install application and
restart your computer from the hard drive where
Mac OS 9.x is installed. 10-1
