8 MB firmware binary labelled BAT-TIS V1.23, which looks like a BIOS version 1.23 for a board identified by the code BAT-TIS. The name does not state the manufacturer, so verify the target board before use. An 8 MB image matches a 64 Mbit SPI flash chip and is normally written with an external programmer such as a CH341A to revive a board that will not boot. Read and save the existing chip contents before erasing, and check that the chip on the board has the same capacity.
