ecc722ad 17 This function provides a platform-specific method to detect whether the platform\r
18 is operating by a physically present user. \r
19\r
20 Programmatic changing of platform security policy (such as disable Secure Boot,\r
21 or switch between Standard/Custom Secure Boot mode) MUST NOT be possible during\r
22 Boot Services or after exiting EFI Boot Services. Only a physically present user\r
23 is allowed to perform these operations.\r

0c18794e 25 NOTE THAT: This function cannot depend on any EFI Variable Service since they are\r
26 not available when this function is called in AuthenticateVariable driver.\r
