The following are the installation options available:

Desktop

The default is CDE for new and complete overwrite installations. If you select NONE, a minimal configuration is installed including X11, Java, perl, SMIT, and the Web-based System Manager (if Graphics Software is selected).

If you select GNOME or KDE, the BOS installation process prompts you for the AIX Toolbox for Linux Applications CD. If this CD is not available, you can type q to continue the installation without the AIX Toolbox for Linux Applications CD.

Enable Trusted Computing Base

The Trusted Computing Base (TCB) is the part of the system that is responsible for enforcing the information security policies of the system. All of the computer's hardware is included in the TCB, but a person administering the system should be concerned primarily with the software components of the TCB.

If you install the Trusted Computing Base option, you enable the trusted path, trusted shell, and system-integrity checking (tcbck command). These features can be enabled only during BOS installation.

The choices are yes and no. To enable the Trusted Computing Base, type 2 and press Enter. The default is no.

Enable CAPP and EAL4+ Technology

Available in a new and complete overwrite installation. If you enable Controlled Access Protection Profile (CAPP) and Evaluation Assurance Level 4+ (EAL4+), other restrictions exist on installation choices, such as:

• Desktop = CDE or NONE
• TCB = yes
• 64-bit kernel = yes
• JFS2 = yes
• Enable System Backups to install any system (Installs all devices and kernels) = no
• Install more software options = no

For information about CAPP and EAL4+, see Controlled Access Protection Profile and Evaluation Assurance Level 4+ in the AIX 5L Version 5.2 Security Guide.

Import User Volume Groups

Available in migration installation and preservation installation. You have the option to have user volume groups imported after the installation completes. These volume groups can be manually imported at a later time.

Enable 64-bit Kernel

Available only on 64-bit Common Hardware Reference Platform (CHRP) systems.
To toggle the choice between no (the default) and yes, type 3 and press Enter. If you choose no, the 64-bit kernel is still installed, but it is not linked to the running /unix. If you choose yes, the 64-bit kernel is installed and begins running when your system reboots.

Create JFS2 File Systems

Available in new and complete overwrite installation, as well as preservation installation with 64-bit kernel enabled option. Create enhanced journaled file systems during BOS installation.

Graphics Software

Available in new and complete overwrite installation, as well as preservation installation. Install graphics software support.

Documentation Services Software

Available in new and complete overwrite installation, as well as preservation installation. Install the documentation services software.

Remove Java 1.1.8 Software

Available in migration installation and preservation installation. You have the option to have all Java version 1.1.8 software removed.

Enable System Backups

If Enable System Backups to install any system is selected, all devices and kernels are installed, so that a system backup can be installed on a different system. For more information about installing a system backup to a different system, see Cloning a System Backup.

The Install More Software option is available in the new and complete overwrite installation method, as well as the preservation installation method. Select Install More Software to choose additional software to install after the BOS installation process finishes. A software bundle file corresponds to each selection that contains the required packages and filesets. The following software bundles are available:
