DFI image file format:
32-byte header 16-byte padding MBR-partitioned disk image FAT16 filesystem
CE.CEX format: Weird. Looks like a debian archive, but it's not. More specifically, it appears to be a debian archive header that's been overwritten with other values in certain places: 64-byte header with overwrite at 0x10-0x13 and 0x30-0x37, with the actual data payload starting at 0x40 instead of 0x44 0x10-0x13 contains the hex value '27 5b c9 47', or '[EG in ascii The useful bits are at offset 0x30-0x37, two little-endian encoded int32 sizes (including headers), representing the sizes of the two chunks in the file: First chunk is a 64-byte header (since it includes the file header) and a tar.gz Second chunk is an empty debian archive.
