Second copy of the Samsung NP300E5Z BIOS image, 4.00 MB in .bin format. As with the first copy, only the model is stated, with no board revision or version. Keeping two dumps lets a technician compare them byte by byte to spot a bad read or confirm both are identical. The size fits a 32 Mbit SPI flash chip, written with tools such as CH341A, TL866 or RT809. Always save the existing chip contents first and verify the written image against the file 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 @biosfilebins. Enginerys does not host this file.
