BIOS image for the ASUS BU403UA laptop, board revision 2.1, with the Management Engine region cleaned, supplied in a 6.34 MB ZIP archive. A cleaned ME region lets the dump be programmed onto a replacement or corrupted chip without inheriting another unit's ME state. Write it to the SPI flash with an external programmer, first reading and saving the original contents, which may carry serial and licence data. Check that the PCB is revision 2.1 and that the image size fits the installed flash chip.
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.
