BIOS and EC firmware package for a board labelled LTM11 with motherboard number 13247-2, a numbering style associated with Wistron. No laptop brand or model appears in the name. The 4.24 MB RAR should contain both the system BIOS image and the embedded controller firmware, useful when a machine is dead, will not charge or fails to power on after a bad flash. Program each image to its proper chip, save the original contents first and confirm the board number on the PCB.
