Mac OS X can be installed on a single partition
along with Mac OS 9.x. You can also install Mac OS X on one
partition or volume while Mac OS 9.x is installed on another. Mac
OS X can also be installed by itself, without Mac OS 9.x. You can
also choose to update a previous version of Mac OS X to Mac OS X
10.4.
Before installing Mac OS X, you should make a
backup of the data on your hard disk, read the Read Before You
Install document, collect network configuration information from
Mac OS 9.x, upgrade firmware (if necessary), and upgrade to Mac OS
9.2.2 (if you plan on using Classic applications).
The initial local account is automatically an
administrator account with which you can change settings in System
Preferences, install applications, and use certain utilities.
Check the installation log; confirm that
firmware is up-to-date; restart/reinstall; check for disk problems;
disconnect nonessential hardware; and turn off Energy Saver and
Screen Saver preferences.
