RAR archive of around 9 MB called GeoBooks, a name that indicates no specific board number, revision or file contents. It probably relates to Geo-branded laptops, but the archive must be opened to learn whether it holds BIOS dumps, schematics or boardview files. Before relying on anything inside, compare the board number printed on the PCB with what each file states. If it contains firmware, read and save the existing flash chip with a programmer before writing, and check that the image size matches the chip capacity.
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 @biositechyangiyer. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
