Installing Mac OS 9

Your computer does not come with Mac OS 9 installed. To use Mac OS 9 applications
with your computer, you have to install Mac OS 9 using the Mac OS X Install Disc 2.

To install Mac OS 9:

1

Back up your important files, if possible.

2

Insert the Mac OS X Install Disc 2 that came with your computer.

3

Double-click “Install Mac OS 9 System Support.”

4

Follow the onscreen instructions.

5

Select the destination disk for installation and continue following the onscreen
instructions.

Maximizing Ethernet Performance

Your computer performs best when the Ethernet port to which it is connected is set to
auto-negotiate. Ask your network administrator to verify this setting.

Important:

If you experience connection problems on your network, make sure your

network switch is set to auto-negotiate, if possible. If a switch’s port is not auto-
negotiating, your computer detects the appropriate speed but defaults to half-duplex
mode. If the switch’s port at the other end of the link is configured for full-duplex
mode, a large number of late events can occur on the link. If it isn’t possible to set the
switch to auto-negotiate, then set the switch’s port to half-duplex. For more
information, see the documentation that came with the Ethernet switch.

Note: If you connect your computer directly to a configurable Ethernet switch, have
your network administrator disable spanning tree on that port. Otherwise your
computer may duplicate the AppleTalk address of another computer on the same
network and both network connections may become unreliable.

Locating Your Product Serial Number

System Profiler shows the serial number of your computer. Open System Profiler (in
Applications/Utilities) and click the System Profile tab.

The serial number of your Power Mac G5 is also on the configuration label, which is
located inside the side panel, directly below the air deflector.
