ASUS X550VXK repair archive for board revision 2, sized at 107 MB and likely holding several resources such as schematics, boardview and BIOS. Check the contents after extraction. With these files you can trace power sequencing, measure rails at test points, locate shorted components and restore a corrupted BIOS using an SPI programmer. Verify the revision printed on the motherboard matches revision 2, and read and store the original flash contents before writing a new image.
