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.
For instructions, see Accessing the Host Console.
