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 Encore/ZIF
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 Encore/ZIF 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 Encore/ZIF 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 installa-
tion. 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.
