BIOS firmware for the Samsung NP940X3G laptop with mainboard BA41-02257A, stored as a RAR archive of 4.08 MB. Samsung uses BA41- numbers for its own motherboard designs, and closely related numbers can indicate different variants of the same model. The image serves for reprogramming the SPI flash with an external programmer when the system will not start after a failed update. Read the label on the board to confirm BA41-02257A, back up the existing chip, and confirm the file size matches the flash device.
