Binary BIOS image for the ASUS K53SD laptop, described in the name as New MCS. The name does not say what MCS stands for, so treat it as an uploader label marking a newer copy. At 4 MB the file matches a 32 Mbit SPI chip and can be loaded into most programmer software as is. Typical uses are reviving a bricked board or clearing a corrupted BIOS region. Back up the existing chip first and verify the board revision on the PCB before writing this image.
