8 MB dump read from a Macronix MX25L6405 SPI chip, named by the programmer with the chip type and an October 2018 timestamp. The source machine is not stated. MX25L6405 is a 64 Mbit part common on boards of that period, so the image fits chips of the same capacity. Use a hex editor to look for model text inside. Back up the original chip and confirm the board matches before reflashing, so a wrong image does not leave the unit dead.
