Restoring and customizing configuration settings
You can reset all configuration settings to the factory default settings, or you can restore system default
configuration settings, which are used instead of the factory default settings.
You can also configure default settings as necessary, and then save the configuration as the custom
default configuration. When the system loads the default settings, it uses the custom default settings
instead of the factory defaults.
Secure Boot configuration
Secure Boot is integrated in the UEFI specification on which the Hewlett Packard Enterprise
implementation of UEFI is based. Secure Boot is completely implemented in the BIOS and does not
require special hardware. It ensures that each component launched during the boot process is digitally
signed and that the signature is validated against a set of trusted certificates embedded in the UEFI BIOS.
Secure Boot validates the software identity of the following components in the boot process:
•
UEFI drivers loaded from PCIe cards
•
UEFI drivers loaded from mass storage devices
•
Pre-boot UEFI shell applications
•
OS UEFI boot loaders
Once enabled, only firmware components and operating systems with boot loaders that have an
appropriate digital signature can execute during the boot process. Only operating systems that support
Secure Boot and have an EFI boot loader signed with one of the authorized keys can boot when Secure
Boot is enabled. For more information about supported operating systems, see the
HPE UEFI System
Utilities and Shell Release Notes for HPE ProLiant Gen9 Servers
on the Hewlett Packard Enterprise
website (

A physically present user can customize the certificates embedded in the UEFI BIOS by adding/removing
their own certificates.
When Secure Boot is enabled, the System Maintenance Switch does not restore all manufacturing
defaults when set to the ON position. For security reasons, the following are not restored to defaults when
the System Maintenance Switch is in the ON position:
•
Secure Boot is not disabled and remains enabled.
•
The Boot Mode remains in UEFI Boot Mode even if the default boot mode is Legacy Boot Mode.
•
The Secure Boot Database is not restored to its default state.
•
iSCSI Software Initiator configuration settings are not restored to defaults.
Embedded UEFI shell
The system BIOS in all ProLiant Gen9 servers includes an Embedded UEFI Shell in the ROM. The UEFI
Shell environment provides an API, a command line prompt, and a set of CLIs that allow scripting, file
manipulation, and system information. These features enhance the capabilities of the UEFI System
Utilities.
