BIOS image for the ThinkPad T430s on Wistron board 11263-2, the second revision of that project, packed in a ZIP archive of around 4.8 MB. The name gives no BIOS version, ME status or chip type, so inspect the extracted files before flashing. Technicians use such dumps to recover a board with corrupted firmware by writing the SPI flash with a hardware programmer. Save the original contents first so serial data can be restored, and make sure the file size equals the flash chip capacity.
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.
