BIOS firmware archive for the ASUS-style X550IUAS model designation, with 307 given in the name, most likely the BIOS version number. The ZIP holds a 2.84 MB package whose exact contents are not listed, so open it and confirm the image type before use. Technicians use such images to recover a corrupted or bricked board by writing the SPI flash with an external programmer such as a CH341A. Read and save the original chip contents first, and check that the image size equals the flash capacity, since a mismatched file will not fit.
