Working BIOS package for the ASUS X513UA, board revision 2.2, shipped as a 21.6 MB RAR; the flash size is not given in the name, so check the image length against the chip on the board. The larger archive size suggests more than one file may be inside, so inspect the contents before use. Program the SPI flash with an external programmer when the laptop fails to start because of corrupted firmware, backing up the original first and confirming the PCB reads R2.2.
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.
