Hi Pascal, This document makes an attempt at an explanation, but in a somewhat obtuse way: http://conventions.cnb.uam.es/References/maplib.html. The important point is that the machine stamp is 4 bytes that are specific for the architecture that wrote the file. For little endian hardware the stamp is 0x44, 0x41, 0x00, 0x00 while the big endian stamp is 0x11, 0x11, 0x00, 0x00.
