BIOS archive for the Lenovo ThinkPad L430 with motherboard number 11248-3, compressed as a 3.14 MB RAR. The five-digit number with a dash revision matches Wistron's board-numbering scheme, and Wistron was the ODM behind this ThinkPad. Technicians write the extracted image to the SPI flash with a programmer to revive a board with corrupted firmware. Confirm that the number on the PCB matches, read and archive the original chip contents before writing, since it holds machine-specific data, and check that the image size matches the chip.
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.
