Verify the UEFI Optimal Defaults

In the BIOS Setup Utility, you can set optimal defaults, as well as view and edit UEFI settings, as needed. By setting optimal defaults, you ensure that the server is operating efficiently with a configuration that is known to be good. You can review the optimal defaults in the Oracle Server X6-2L Service Manual.

Any changes you make in the BIOS Setup Utility using the F2 key are permanent until the next time you change them.

In addition to using the F2 key to view or edit the system's BIOS settings, you can use the F8 key during the boot process to specify a temporary boot device. If you use F8 to set a temporary boot device, this change is only in effect for the current system boot. The permanent boot device specified through F2 will be in effect after booting from the temporary boot device.

Before you begin, ensure that the following requirements are met:

• The server is equipped with a hard disk drive (HDD) or solid state drive (SSD).

• The HDD or SSD is properly installed in the server. For instructions, refer to Servicing Storage Drives and Rear Drives (CRU) in Oracle Server X6-2L Service Manual.

• A console session is established to the server. For details, see Selecting the Console Display.

The following server BIOS settings may be required to use Oracle VM Server:

• AHCI mode may be necessary to recognize the CDROM device to perform an installation from CDROM.

• Disable I/O MMU Virtualization Settings; for Intel-based servers this is VT-d. I/O MMU (I/O Memory Management Unit) is not supported in this release.

1. Power on or reset the server.

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

   • From the local server, press the Power button on the front panel of the server (for approximately 1 second) to power off the server, and then press the Power button again to power on the server.

   • From the Oracle ILOM web interface, select 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.
