ASUS BIOS for the GA401IV board revision 1.04 fitted with an AMD Ryzen 7 CPU, reported as a working image and stored in a RAR archive of 12.6 MB. The CPU note matters because BIOS builds can differ between processor options on the same board. Write it to the SPI flash chip with a programmer when the laptop shows no display or fails after a bad update. Check the revision on the PCB matches, confirm the image size fits the chip, and back up the original contents first.
