Compressed RAR package with BIOS firmware for the Samsung NP300E5V laptop, 5.68 MB in size, which suggests more than one image or a large full dump inside. The name offers no board number, revision or version details. Check each extracted file against the capacity of the flash chip on your board, since a mismatched image will not fit. Write it with an external SPI programmer after reading and saving the existing contents, and confirm the board code on the PCB matches.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
