An 8 MB binary read from a Macronix MX25L6405 serial flash, named only with the programmer's date and time stamp of 4 February 2019. No laptop model, motherboard number or BIOS revision is indicated, so its origin must be confirmed before use. The size matches the 64 Mbit capacity of the MX25L6405, so a CH341A-type programmer can write it back. Check the image in UEFITool or a hex editor to identify the platform, and save the original chip contents first so the board can be restored if the result fails.
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 @biosfilebins. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
