Toshiba BIOS image in a RAR archive; the name gives FAL5SY2 and A2971 A, which look like the board code and revision marking, though the laptop model is not stated. Before using it, compare these markings with the silkscreen on your motherboard. Such dumps are flashed to the SPI chip with an external programmer to revive a board with corrupted firmware. Read and keep the original contents first, check that the file size equals the chip capacity, and expect serial or system data to need restoring afterward.
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.
