BIOS for the Samsung NP300E5A in its UMA configuration, meaning integrated graphics without a discrete GPU. A dump for a dedicated graphics variant would differ, so check whether the board carries a separate graphics chip before writing. The 2.1 MB 7z archive needs 7-Zip or similar to extract. Program the SPI flash with an external programmer after reading the original. Confirm the image length matches the chip capacity, since a mismatched dump will not fit.
