A second copy of an ASUS N53S BIOS dump, distinguished from the first only by a duplicate number in the name. It is a 4.00 MB raw binary with no stated revision, version or verification. Keeping alternate dumps is useful when one image fails to boot a repaired board, since a technician can try another through an SPI programmer. Compare checksums against the other copy to see whether they differ, back up the original flash first, and confirm the chip on the board is 4 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 @abgm_manutencao_bios. Enginerys does not host this file.
How to open a .bin 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 →
