BIOS firmware archive for the MSI CX620 laptop, packed as a 1.50 MB RAR. The file name gives only the model, so no board number, revision or BIOS version is stated and the contents should be inspected before use. MSI notebooks carry an MS-xxxx board code on the PCB, and that code should be confirmed against any readme inside the archive. Before flashing with an SPI programmer, read and save the original chip contents, then make sure the image size matches the capacity of the flash chip fitted on the board.
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.
