BIOS image for the ASUS X505ZA laptop at board revision 2.0, packaged in a 4.32 MB RAR. The X505ZA is an AMD Ryzen based model. The dump is used to recover a machine with no display or a failed update by programming the SPI chip directly with a CH341A or similar tool. Verify the revision printed on the motherboard, read and save the original chip first to preserve serial and DMI data, and check that the image matches the flash chip capacity before writing.
