-// The BIOS initializes MemoryOverwriteRequestControlLock to a value of 0x00\r
-// before BDS (BOOT#### processing). When the OS loader calls SetVariable by\r
-// specifying 0x01, the access mode for both MemoryOverwriteRequestControlLock\r
-// and MemoryOverwriteRequestControl is changed to read-only. If any other\r
-// value is specified in the SetVariable call, it fails with the \r
-// EFI_INVALID_PARAMETER error code.\r

+// Note: Setting MemoryOverwriteRequestControlLock does not commit to flash (just changes the internal lock state).\r
+// Getting the variable returns the internal state and never exposes the key.\r
