Apple Power Macintosh 9600 - Manual (Page 178)

Installing system software
Your Macintosh came with all the necessary system software installed on its
internal hard disk, so you don’t need to install system software on that disk
unless you encounter software problems.
When should you install system software?
m You have a new hard disk or a newly initialized hard disk that does not yet
contain system software. Follow the instructions in “Performing a Normal
or Easy Installation of System Software” later in this section.
m You want to upgrade to a more recent version of system software. Follow
the instructions that came with your system software upgrade, or the ones
in “Performing a Normal or Easy Installation of System Software” later in
this section.
IMPORTANT If you’re having a problem with your system software, you may
not need to reinstall system software. If you see an icon like this in the
middle of the screen, follow the instructions in “Testing and Repairing Your
Hard Disk” earlier in this chapter to test your startup hard disk and repair
any damage.
If repairing the disk doesn’t help, follow the instructions that follow to
reinstall system software on your startup hard disk.
