BIOS file for the ASUS ET2311I all-in-one, version 1403, reported working. The name gives no board revision, so confirm the mainboard is the ET2311I before use. Such an image is typically written to the SPI flash chip with a programmer to recover a unit that powers on without display or after a failed update. Extract the RAR first, read and save the original chip contents, and make sure the image size corresponds to the chip capacity, otherwise the write will not fit or verify.
