UEFI System Utilities UEFI System Utilities
The UEFI System Utilities is embedded in the system ROM. Its features enable you to perform a wide range of configuration activities,
including:
Configuring system devices and installed options.
Enabling and disabling system features.
Displaying system information.
Selecting the primary boot controller or partition.
Configuring memory options.
Launching other preboot environments.
HPE servers with UEFI can provide:
Support for boot partitions larger than 2.2 TB. Such configurations could previously only be used for boot drives when using RAID
solutions.
Secure Boot that enables the system firmware, option card firmware, operating systems, and software collaborate to enhance
platform security.
UEFI Graphical User Interface (GUI)
An Embedded UEFI Shell that provides a preboot environment for running scripts and tools.
Boot support for option cards that only support a UEFI option ROM.
Selecting the boot mode Selecting the boot mode
This server provides two Boot Mode configurations: UEFI Mode and Legacy BIOS Mode. Certain boot options require that you select a
specific boot mode. By default, the boot mode is set to UEFI Mode. The system must boot in UEFI Mode to use certain options,
including:
Secure Boot, UEFI Optimized Boot, Generic USB Boot, IPv6 PXE Boot, iSCSI Boot, NVMe Boot and Boot from URL
Fibre Channel/FCoE Scan Policy
NOTE: NOTE:
The boot mode you use must match the operating system installation. If not, changing the boot mode can impact the
ability of the server to boot to the installed operating system.
