BIOS dump for the Lenovo ThinkPad T540p on Wistron motherboard 12308-2. The archive of about 5.6 MB likely contains the main SPI image, which can be written with an external programmer to recover a board with a corrupted BIOS. ThinkPad firmware holds serial, UUID and sometimes supervisor password data, so read and keep the original chip contents before writing. Check that the board number matches and that the image size equals the capacity of the flash chip fitted on your PCB.
