A 4 MB BIOS binary for the ASUS N53JG notebook, with the name marking it as ok, presumably a working, tested dump. The name gives no board revision or version. The size matches a 4 MB (32 Mbit) SPI flash, so it can be written with a programmer such as a CH341A or RT809 to restore a corrupted BIOS. Confirm the chip on your board is also 4 MB, save the original contents first, and note that serial and system data in a donor dump may need correcting.
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 @biosbigarchives. 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 →
