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
installation to enable AltiVec on your Encore/ZIF G4-upgraded
Power Macintosh (when no G4 processor was installed in your
system before).
1.
Complete the installation of the Encore/ZIF processor
upgrade card, then turn on your computer.
2.
Insert the Mac OS 9 CD into your CD-ROM drive. In the
finder menu, select Special: Restart, then immediately press
and hold down the C key on your keyboard until your sys-
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..
Installing Additional Software
Support Note:
If you upgrade to Mac OS 9.1 or 9.2, AltiVec
support is installed automatically; the procedure detailed
below will be unnecessary.
