Verified Boot can be used to verify system boot blocks and Oracle Solaris kernel modules before they are loaded on the system. Use Oracle ILOM to enable Verified Boot and to specify how the system should respond when a verification check fails. Enabling Verified Boot can prevent harmful changes to the system boot blocks or Oracle Solaris kernel modules from taking effect.
Refer to the information about configuring SPARC Verified Boot properties in Oracle ILOM Administrator's Guide for Configuration and Maintenance.
