Firmware for the Samsung NP550P7C laptop, platform code name McLaren, on Samsung board BA41-01900A. Packed as a 2.85 MB RAR, it provides the image for direct SPI flash programming during repair of no-boot or bricked units. Samsung numbers its own boards with the BA41 prefix, and this code should be found on the PCB before use. Different revisions of the same platform may need different files, so check the board label, dump the original chip first and ensure the extracted file matches the flash size.
