This section covers the installation of additional software your system 
may require to fully support the Encore/ZIF G4 processor upgrade 
card. Complete the steps on the following pages after you have suc-
cessfully installed the Encore/ZIF card. 

Check the requirements listed below to determine which, if any, addi-
tional software you must install. If you have multiple operating sys-
tems 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 26 regarding updating your Mac OS X software

.

•  

Mac OS 8.6

: No additional software installation is required; you 

may skip this section if OS 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). 
You do not need to perform this installation if you replaced an exist-
ing G4 processor card.

•  

Mac OS 9.1.x or 9.2.x

: No additional software installation is 

required; you may skip this section if OS 9.1.x or 9.2.x is your sys-
tem’s only OS.

•  

Mac OS X (any version)

: You must run the SonnetCache install 

application; this software enables L2 and L3 cache support for the 
Encore/ZIF G4 card under OS X (see page 25). Also, unless you are 
using a Power Mac G4 (PCI Graphics) system, you must install a 
bootable Mac OS 9.1.x or 9.2.x System Folder (selectable from System 
Preferences) if your system does not have one*. 

Enable AltiVec—Existing OS 9.0.x installation

This section describes how to update an existing Mac OS 9.0.x

Power Macintosh (when no G4 processor was installed in your 
system before).

tem restarts and the 

Welcome to Mac OS 

screen appears.

 

*  Options for completing this task include A) installing Mac OS 9.1.x or 9.2.x on one of 

your Mac OS X hard drives, B) connecting a spare hard drive inside your computer and 
installing Mac OS 9.1.x or 9.2.x, or C) reformatting your existing hard drive with two or 
more partitions (erasing all data on the drive in the process), and then installing Mac 
OS 9.1.x or 9.2.x on one partition, Mac OS X on another..
