Raw 4.00 MB BIOS binary identified only as ASUS N53S, with no board revision, version number or tested status in its name. The size suits a 4 MB (32 Mbit) SPI flash, and the file would usually be written with a CH341A or similar programmer to restore a notebook that powers up without display or loops on boot. Before flashing, read and keep the existing chip contents, confirm the motherboard is the N53S series, and compare the dump against other copies if one is available.
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 @abgm_manutencao_bios. Enginerys does not host this file.
