BIOS image for the ASUS N53SV notebook, motherboard revision 2.0. The compact 1.48 MB archive matches the smaller flash chips common on that generation. Use it to recover a board with corrupted firmware by programming the SPI chip directly. Check that the PCB carries the same revision, since a mismatched image can cause no-boot or fan and power issues. Read and save the current chip contents first, then confirm the extracted image size equals the flash capacity before writing.
