Firmware for a TG-K4-5 board, with the code IOT91 and version 1.0 appearing in the name, packed as a 508 KB zip. The meaning of IOT91 is not stated, so treat it as an identifier to match against the PCB markings. The image is meant for reprogramming the BIOS chip with an external programmer when the board shows no POST or a corrupted setup. Back up the original chip before writing, compare all labels printed on the board with the name, and verify that the dump size matches the chip.
