Small BIN image, 400 KB packed, for the IBM System x3100 M4 server, labelled revision 1.04. The name does not say which chip it belongs to. The small size suggests it may be a secondary firmware rather than the full 16MB system BIOS. Before writing it with a programmer, compare the image size with the flash chip capacity, because a size mismatch means it is for a different device. Read and keep the original contents of the chip.
