Working BIOS dump, marked OK in the name, for the Lenovo E49AL on the 11310-1 LSS-1 motherboard, PCB number 4TK01.011. The 11310 board number follows the Wistron numbering scheme, the ODM behind this Lenovo model. A tested image like this is useful for reviving a board stuck with corrupted firmware after a failed update. Confirm the -1 variant on the PCB before flashing, keep a copy of the original chip contents, and check that the file size matches the flash chip before writing it with a programmer.
