ASUS N55SF BIOS image, 4.00 MB in raw binary format, with no board revision, version or status given in the name. The size corresponds to a 32 Mbit SPI flash chip used on this Sandy Bridge era multimedia notebook.

Because the name is minimal, confirm the image is complete and matches your board revision, and read out the original chip before replacing its contents.
