UEFI System Utilities

The UEFI System Utilities is embedded in the system ROM. The UEFI System Utilities 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
• Configuring memory options
• Selecting a language
• Launching other preboot environments such as the Embedded UEFI Shell and Intelligent Provisioning
For more information, see the UEFI System Utilities user guide for your product on the Hewlett Packard
Enterprise website.
To access mobile-ready online help for the UEFI System Utilities and UEFI Shell, scan the QR code at the
bottom of the screen. For on-screen help, press the F1 key.

Flexible boot control

This feature enables you to do the following:
• Add Boot Options:
◦ Browse all FAT16 and FAT32 file systems.
◦ To add a new UEFI boot option, select an X64 UEFI application with an .EFI extension. For
example, adding an OS boot loader or other UEFI application as a new UEFI boot option.
The new boot option is appended to the boot-order list. When you select a file, you are prompted to
enter the boot option description. This description, and any optional data to be passed to an .EFI
application, is then displayed in the boot menu.
• Boot to System Utilities
After pre-POST, the boot options screen appears. During this time, you can access the UEFI System
Utilities by pressing the F9 key.
• Choose between supported modes:
◦ Legacy BIOS Boot Mode
◦ UEFI Boot Mode
IMPORTANT:
If the default boot mode settings are different than the user-defined settings, the system might
not boot the OS installation if the defaults are restored. To avoid this issue, use the User
Defined Defaults feature in UEFI System Utilities to override the factory default settings.
