Firmware archive for the ASUS R558U laptop based on the X556UV motherboard, revision 3.1, packed as a 3.69 MB RAR. The name does not specify CPU or GPU variant, so check which configuration your board carries before flashing. A dump like this is written directly to the SPI BIOS chip using an external programmer to recover a board with corrupted firmware. Always read and keep the original contents first, verify the board revision on the silkscreen, and ensure the image matches the chip capacity.
