128 KB binary for the Acer Aspire 5740G, labelled small and OKOK, meaning it was reported working. The small tag and size indicate this is the smaller of two chips on the board, most likely the embedded controller or keyboard controller firmware, paired with a separate larger main BIOS file. Flash it with a programmer that supports the target chip after reading out a backup. Make sure the chip on your board is also 128 KB, otherwise the image will not fit correctly.
