BIOS archive for the ASUS X556UF, 3.81 MB in a ZIP, referencing the X556UJ mainboard at revision 2.0, which ASUS uses across related X556U models. Extract it and program the SPI flash with a programmer to repair boot failures or a corrupted firmware. ASUS boards carry the model and revision printed on the PCB, so confirm that it reads X556UJ Rev 2.0. Save the original dump first to keep the serial and MAC data, and check that the image size matches the chip.
