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 all supported Linux operating systems support 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.

1. Reset or power on the server.

   For example, to reset the server, 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, and 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, and then click Save.

   • From the Oracle ILOM CLI, type: reset /System

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