216 1) the addition of boot option.\r
217 2) the addition of driver option.\r
218 3) exit from file browser\r
219 4) update of file content if a dir is selected.\r
220 5) boot the file if a file is selected in "boot from file"\r

222\r
223 @param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.\r
224 @param Action Specifies the type of action taken by the browser.\r
225 @param QuestionId A unique value which is sent to the original exporting driver\r
226 so that it can identify the type of data to expect.\r
227 @param Type The type of value for the question.\r
228 @param Value A pointer to the data being sent to the original exporting driver.\r
229 @param ActionRequest On return, points to the action requested by the callback function.\r

234 @retval EFI_UNSUPPORTED The specified Action is not supported by the callback.\r
