BIOS archive for the MSI CX420 notebook on motherboard MS-14531. MSI designs and numbers its own boards in the MS-xxxx format, and the extra digit usually marks a board sub-version. The RAR is about 1.5 MB, so the image inside is likely sized for a small SPI chip, though its exact contents are not described. Check that MS-14531 appears on your PCB and back up the current chip before writing. Also confirm that the dump size matches the flash capacity reported by your programmer software.
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.
