== Dune Firmware ==

The dune firmware has an unknown header of $100 bytes, consisting of string identifier and several large integers. Most likely file-size, offsets and checksums.

In side the large file we have several parts. In no particular order, vmlinux.gz, which has the rootfs cpio attached, the main cramfs file-system as well as the usual romfs for SMP ucodes.

The file-sizes are not correct, I just dd from the right point until the end.

TODO: Check for uh.. checksum and algorithm.

TODO: Look at the .dsf (Dune service file) which can arbitrarily execute files. Here is a .dsf header:
