• • • `LoadImage()`

• - The LoadImage() boot service is not required to install an
  

•   EFI_HII_PACKAGE_LIST_PROTOCOL for an image containing a custom PE/COFF
  

•   resource with the type 'HII'. - HII resource images are not needed to run
  

•   the UEFI shell or the SCT.
  

• • • `ConnectController()`

• - The ConnectController()` boot service is not required to support the
  

•   EFI_PLATFORM_DRIVER_OVERRIDE_PROTOCOL,
  

•   EFI_DRIVER_FAMILY_OVERRIDE_PROTOCOL, and
  

•   EFI_BUS_SPECIFIC_DRIVER_OVERRIDE_PROTOCOL. - These override protocols are
  

•   only useful if drivers are loaded as EFI binaries by the firmware.
  

  • • `EFI_HII_CONFIG_ACCESS_PROTOCOL`
    • UEFI requires this for console devices, but it is rarely necessary in practice. Therefore this protocol is not required.
