Firmware dump packed in a RAR archive of 2.82 MB, named after a Macronix MX25L3205 SPI flash chip and a date-time stamp from January 2020, which looks like an automatic programmer read. The name states no laptop model or board number, so the source device is unknown. The MX25L3205 is a 32 Mbit (4 MB) part, so the image should only go back onto a chip of that capacity. Confirm the exact board it came from before writing it, and always save a backup of the original chip first with 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 @SCHEMATICWORLD. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
