BIOS archive for the MSI CX620 notebook, delivered as a 1.50 MB RAR with no board number, revision or version stated in the name. Extract it to check whether it holds a raw SPI dump or an update file, and note the image size. Technicians use such firmware to recover boards with corrupted BIOS using a hardware programmer. The PCB marking should match the source board, since MSI uses MS-xxxx board numbers that differ between variants. Read and keep the original chip contents before writing.
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.
