Platform Names and Groups
When you are  adding clients for a network installation, you must
know your system architecture (platform group). If you are writing a custom JumpStart installation
rules file, you need to know the platform name.
Some examples of platform names and groups follow. For a full list
of SPARC based systems, see Solaris Sun Hardware Platform Guide at http://docs.sun.com/.
