Lenovo BIOS binary for the LT41MB board, Wistron number 14217-1M, delivered as a 3.44 MB ZIP containing a BIN image. The five-digit number with a dash suffix follows Wistron's board naming, used across many Lenovo consumer laptops. Such a raw dump is flashed directly onto the SPI chip with a hardware programmer when the machine fails to boot or shows a black screen. Confirm the board marking matches, save the original chip contents first, and check that the file size equals the flash capacity before writing.
