Samsung NP500 series BIOS dump, 8.00 MB and without a file extension, sized for a 64 Mbit SPI flash. The name does not give the exact submodel, board number or firmware version, and NP500 spans many configurations, so identify the BA41 board code on the PCB before writing. Load it as a raw binary in the programmer software. Read and keep the original chip contents first, compare by checksum with the other NP500 copy, and verify after flashing.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
