Firmware dump of 8.00 MB, matching a 64 Mbit SPI chip, labelled WS03 with ME and REVB, apparently a backup from a Chinese-made board, as the Spanish words placa china and BCKP suggest. Brand and model are not stated, so identify the target from the WS03 marking and revision B on the PCB. Such backups are written with a programmer like the CH341A to restore a board after a bad flash. Back up the current chip first and confirm its capacity is 8 MB 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 @LCS_Biossolutions. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
