Set the Boot Mode

The server is equipped with Unified Extensible Firmware Interface (UEFI), which supports both Legacy BIOS and UEFI boot modes. Legacy BIOS boot mode is enabled by default.

VMware ESXi supports both Legacy BIOS and UEFI boot modes. However, you must run the software in the boot mode in which it was installed. That is, after you have installed VMWare ESXi, if you decide you want to switch boot modes, you must reinstall the software. Before you install VMware ESXi, determine which boot mode is appropriate for your environment.

1. Access the host console.

   For instructions, see Accessing the Host Console.

2. 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, and then select Reset from the Select Action list box.

   • From the Oracle ILOM command-line interface, type reset /System.

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