Tested BIOS image for the Lenovo ThinkPad L430, for the Wistron-made mainboard numbered 11248-3. Wistron uses five-digit project numbers with a revision suffix on ThinkPad boards, printed on the PCB. The dump is used to recover a board with corrupt firmware, often after a failed update, by writing the SPI flash with a programmer. Check the board number on your unit, read and back up the existing chip to keep machine-specific data, and confirm the file matches the chip size.
