BIOS package for the Lenovo Miix 520-12IKB detachable, machine type 20M3000TRK, in a 4.92 MB RAR. The 12IKB suffix follows Lenovo's convention for a 12-inch Kaby Lake model. The dump is meant for recovering a tablet that stays dark or loops after a firmware failure by programming its SPI chip. Since the name does not mention the board number or ME state, read and keep the original chip first, then confirm the image size equals the chip capacity before writing.
