Oracle Solaris 11.2 adds support for firmware version checking with Oracle Solaris Image Packaging System (IPS). IPS can check installed firmware versions to ensure that they are compatible with driver updates that may occur during a system update. If an incompatibility occurs, IPS prevents the system from being updated and flags that the firmware must be manually updated by the administrator first. For certain hardware drivers, firmware is automatically updated on driver attach to maintain compatibility.
