On\nBig-endian architectures, the memmap_on_memory is consistently displayed\nas 'N' regardless of its actual status.\n\nTo address this endianness problem, the solution involves obtaining the\nmode as an integer.  This adjustment ensures the proper display of the\nmemmap_on_memory parameter, presenting it as one of the following options:\nForce, Y, or N."
