In this release, the following changes have been made:
The eeprom command has be updated to Implement NVRAM storage for EEPROM variables specific to the UEFI environment. See Working With EEPROM Parameters for more information.
Boot support for advanced format (AF) disks. For more information, see Using Advanced Format Disks in Managing Devices in Oracle Solaris 11.2 and the boot (1M) man page.
Booting from GPT labeled disks is now supported on SPARC as well as x86 systems. The installer automatically writes the EFI GPT disk label to the disk if the firmware supports it. The disk will only boot under Sun System Firmware 8.4.0 or later on SPARC T4 systems or Sun System Firmware 9.1.0 or later on SPARC T5 and SPARC M5 systems. If a host is downgraded to an older version of the Sun System Firmware, then the disk will fail to boot.
