Installation—AGP Graphics and Gigabit Ethernet Models

5. Carefully remove the cap covering the connector on the bottom

of the Duet processor card (Figure 13), and then place the cap on
the original processor card’s connector.

6. Place the processor card you removed from the computer into

the anti-static package, and then store it, the original heat sink,
heat sink clips, and the screws you removed in a safe place.

7. Align the connector on the bottom of the Duet card with the

connector on the logic board (Figure 14), and then set the card
down on top of the three threaded posts (not shown). Make sure
the connectors are lined up, then, grasping the Duet card by
its heat sink, gently press it straight down until the connectors
snap together. Verify the connectors are completely coupled by
gently pulling up on the edges of the Encore/ST board; the board
should remain fi rmly in place.

8. Making sure the Duet card’s captive screws are engaged prop-

erly in the threaded posts, tighten each of the three screws and
secure the card snugly to the logic board; do not overtighten the
screws (Figure 15).

Close Computer

1. Raise the side panel back into place (Figure 16).

2. Return the computer to your computing area if necessary, and

reconnect the power cord and peripheral cables to the computer.

Turn On Computer

Turn on your Power Mac; your accelerated machine should boot
normally.

Run Sonnet X Tune-Up

Running the Sonnet X Tune-Up install application is necessary
only when Mac OS X (any version) is installed on your system.
This application installs a fi le that enables Mac OS X to properly
identify processor speed, as well as L2 and L3 cache size and
speed. Remember to install this software when you upgrade to
Mac OS X. For complete information on Sonnet X Tune-Up,
please refer to the Read Me notes provided with the software.

1. Boot your system in Mac OS X from a hard drive or parti-

tion, not a CD-ROM.

2. Insert the Sonnet Installer CD into your CD-ROM drive,

double-click the ST/ZIF OS X Support folder, copy the
Sonnet X Tune-Up file to your desktop, and then eject the
Sonnet Installer CD.

3. Run Sonnet X Tune-Up. After the installation is complete,

restart your system; your installation is complete.
