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

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
