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 11.3 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.

Note -  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.
  1. Reset or power on the server.

    For example, do one of the following to reset the server:

    • From the local server, press the Power button on the front panel of the server (for approximately 1 second) 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 /System

    The server begins the boot process and the BIOS screen appears.

    Note -  The next step occurs very quickly; therefore, be ready to press the F2 key. Watch carefully for messages as they appear on the screen for a brief time.
  2. When prompted in the BIOS screen, press the F2 key to access the BIOS Setup Utility.

    After a few moments, the BIOS Setup Utility appears.

  3. In the BIOS Setup Utility, use the arrow keys to navigate to the Boot menu.

    The Boot Menu screen appears. The UEFI/BIOS Boot Mode field displays the current boot mode.

    Note -  The options in the boot order list differ depending on the storage drive configuration and whether you have enabled the Persistent Boot Support feature. For more information about Persistent Boot Support, refer to the Oracle X6 Series Servers Administration Guide at http://www.oracle.com/goto/x86admindiag/docs.
  4. Use the down arrow key to select the UEFI/BIOS Boot Mode field, and then press Enter.
  5. Select your preferred boot mode, and then press Enter.

    You must select the desired boot mode, Legacy BIOS or UEFI, before starting the operating system installation.

  6. To save your changes and exit the BIOS Setup Utility, press the F10 key.
