Set the Boot Mode
The server UEFI firmware supports both Legacy BIOS and UEFI boot modes. Legacy BIOS Boot Mode
is enabled by default.
Because Oracle Solaris 11.2 supports both Legacy BIOS and UEFI, you have the option of
setting the boot mode to either Legacy BIOS or UEFI before you perform the OS installation.
After you have installed the Oracle Solaris operating system, if you decide you want to switch
from Legacy BIOS Boot Mode to UEFI Boot Mode, or vice versa, you must remove all partitions and
reinstall the operating system.

For example, do one of the following:
From the local server, press the Power button
(approximately 1 second) on the front panel of the server to turn the server off, then press the
Power button again to power on the server.
From the Oracle ILOM web interface, click Host Management
→ Power Control, select Reset from the Select Action list box, then click Save.
From the Oracle ILOM CLI, , type: reset
The server begins the boot process and the BIOS screen appears.

The Boot Menu screen appears.
The options in the boot order list differ depending on the storage drive configuration and
