Firmware archive for the CX620, a model in the MSI notebook range, even though the brand is not given in the name; no board number or revision is included. The RAR is 1.52 MB. Unpack it and check the contents and image size before flashing. A raw dump can be written to the SPI chip with a programmer to revive a machine with no POST. Identify the MSI board number printed on the PCB and compare it with the source, verify the chip capacity, and save the original flash first.
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.
