Operating System Installation: Getting Started
New and Complete Overwrite Installation
Use the following steps to perform a new and complete overwrite installation
of AIX 5.2.
For more information on new and complete overwrite installation, refer
to the Installing the Base Operating System section
in the AIX 5L Version 5.2 Installation Guide and Reference.
Refer to the Network Installation Management (NIM) section in the AIX 5L Version 5.2 Installation Guide and Reference,
if you are performing a network installation of AIX.
Step 1. Prepare Your System
- There must be adequate disk space and memory available. AIX 5.2 requires
128 MB of memory and 2.2 GB of physical disk space. For additional release
information, see the AIX 5L Release Notes.
- Make sure your hardware installation is complete, including all external
devices. See the documentation that came with your system unit for installation
instructions.
- If the system is currently installed, make a backup copy of your system
software and data if you are installing over an existing version of AIX.
For instructions on how to create a system backup, refer to the Creating System Backups section in the AIX 5L Version 5.2 Installation Guide and Reference.
- If your system needs to communicate with other systems and access their
resources, make sure you have the following information before proceeding
with installation:

Step 2. Boot from the AIX Product CD
- Insert the AIX Volume 1 CD into the CD-ROM
device.
- Make sure all external devices attached to the system (such as CD-ROM
drives, tape drives, DVD drives, and terminals) are turned on. Only the CD-ROM
drive from which you will install AIX should contain the installation
media.
- Power on the system.
- When the system beeps twice, press F5 on the keyboard (or 5 on
an ASCII terminal). If you have a graphics display, you will see the keyboard
icon on the screen when the beeps occur. If you have an ASCII terminal (also
called a tty terminal), you will see the word keyboard when the
beeps occur. The system will now boot from the installation media.
Note
If your system does not boot using the F5 key (or the 5 key on
an ASCII terminal), refer to your hardware documentation for information on
how to get your system to boot from an AIX product CD.
- Select the system console by pressing F1 (or 1 on an ASCII
terminal) and press Enter. If you have more than one display or terminal,
follow the instructions on the display or terminal to select one as the console.
- Select the language for the BOS Installation menus by typing the corresponding
number in the Choice field. Press Enter to open the Welcome to Base
