Secure Boot Configuration; Embedded Uefi Shell; Embedded Diagnostics Option; Ilo Restful Api Support For Uefi - HPE ProLiant BL460c Gen10 User Manual

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 Gen10 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 Gen10 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.
For more information, see the following documents:
• HPE UEFI Shell User Guide for HPE ProLiant Gen10 Servers on the Hewlett Packard Enterprise
website
• UEFI Shell Specification on the UEFI website

Embedded Diagnostics option

The system BIOS in all ProLiant Gen10 servers includes an Embedded Diagnostics option in the ROM. The
Embedded Diagnostics option can run comprehensive diagnostics of the server hardware, including
processors, memory, drives, and other server components.
For more information on the Embedded Diagnostics option, see the HPE UEFI System Utilities User Guide for
HPE ProLiant Gen10 Servers on the Hewlett Packard Enterprise website.

iLO RESTful API support for UEFI

The ProLiant Gen10 servers include support for a UEFI compliant System BIOS, along with UEFI System
Utilities and Embedded UEFI Shell pre-boot environments. ProLiant Gen10 servers also support configuring
