To download the AI boot image, go to: http://www.oracle.com/technetwork/server-storage/solaris11/downloads/index.html.
You can use the default manifest that is provided in the AI image or you can create a custom manifest and provide the location of this custom manifest when the client boots. See Creating a Custom AI Manifest.
Boot the system from the device that contains the boot image. See Booting a SPARC System From AI Media and Booting an x86 System From AI Media for instructions about how to specify the default AI manifest or a custom AI manifest.
A “hands-free” installation is performed. After the installation, the SCI Tool starts and asks you to provide configuration information for the system.
