Backup BIOS dump for the ASUS X555QG, revision 2.0 board, stored as a 2.83 MB RAR archive. Being a read from a working unit, it can restore firmware on a matching board that lost its BIOS or shows no display. Write it with an SPI programmer after extracting. Make sure the PCB revision is 2.0 and that the image size matches the flash chip. Keep your own original read too, because serial numbers and other unit-specific data in the dump may differ from your machine.
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.
