Firmware archive for the ASUS X553MA laptop, a ZIP of about 3.23 MB, with no board revision or BIOS version stated in the name. Extract it to find the image, then compare the image size with the SPI flash chip on the mainboard before programming. A dump like this is used to recover a board that powers on without display after a failed update or chip corruption. Check that the PCB matches the X553MA, and read and save the original chip first so the serial and UUID data can be restored.
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 @biosarchive. Enginerys does not host this file.
