In-Band
Manageability
Interface When set to Disabled , this setting will hide the Management Engine's (ME), HECI devices, and the system's IPMI
devices from the operating system. This prevents the operating system from changing the ME power capping

band. This option is set to
Enabled by default.
NOTE: BIOS update requires HECI devices to be operational and DUP updates require IPMI interface to
be operational. This setting needs to be set to Enabled to avoid updating errors.
Secure Boot Enables Secure Boot, where the BIOS authenticates each pre-boot image by using the certificates in the Secure
