BIOS archive for the Samsung NP300E5Z notebook, identified only by its model code, with no board number or revision in the name. The RAR is about 2 MB, so check the extracted image size against the flash chip before writing it. Repair shops flash files like this onto the SPI chip with an external programmer when the laptop powers on without display or loops at startup. Read and save the existing chip contents first, since that backup preserves the serial number and other unit-specific data.
