BIOS backup from a ThinkPad T430s, board 11263-2, LSN-4 design, integrated graphics (UMA), marked as a working backup. The RAR archive is 5.14 MB. Five-digit board numbers with a dash suffix such as 11263-2 follow the Wistron scheme, and Wistron manufactured this Lenovo board. Use the dump to reflash the SPI chip when the machine is dead or bricked. Keep in mind it holds another unit's serial and data. Read your own chip first, and confirm the image size and board revision match.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
