+  "ALTCFG=<StringToken>". That <StringToken> (when

+  string in the associated string pack.
+

+

+  This function is called to provide results data to the driver.

+  @param  This                   Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
+  @param  Action                 Specifies the type of action taken by the browser.
+  @param  QuestionId             A unique value which is sent to the original
+                                 exporting driver so that it can identify the type
+                                 of data to expect. The format of the data tends to
+                                 vary based on the opcode that generated the callback.
+  @param  Type                   The type of value for the question.
+  @param  Value                  A pointer to the data being sent to the original
+                                 exporting driver.
+  @param  ActionRequest          On return, points to the action requested by the
+                                 callback function.
+
+  @retval EFI_SUCCESS            The callback successfully handled the action.
+  @retval EFI_OUT_OF_RESOURCES   Not enough storage is available to hold the
+                                 variable and its data.
+  @retval EFI_DEVICE_ERROR       The variable could not be saved.
