Lenovo ThinkPad L530 BIOS dump for board LBF-1, MB 11270-4, marked as tested and working, in a RAR archive of about 6 MB. The 11270 numbering with a revision suffix follows the Wistron scheme, the maker of this mainboard. A verified image like this is used to recover a unit stuck with no display or a boot loop by reprogramming the SPI flash. ThinkPad dumps can contain machine-specific serial data, so save your original chip first and confirm the board revision printed on the PCB before writing.
