13 | This function provides a platform-specific method to detect whether the platform\r | |
14 | is operating by a physically present user. \r | |
15 | \r | |
16 | Programmatic changing of platform security policy (such as disable Secure Boot,\r | |
17 | or switch between Standard/Custom Secure Boot mode) MUST NOT be possible during\r | |
18 | Boot Services or after exiting EFI Boot Services. Only a physically present user\r | |
19 | is allowed to perform these operations.\r | |

21 | NOTE THAT: This function cannot depend on any EFI Variable Service since they are\r | |
22 | not available when this function is called in AuthenticateVariable driver.\r | |
