+Description of nk.bin from

+http://www.xs4all.nl/~itsme/projects/xda/wince-flashfile-formats.html
+
+these files contain most information, several non-contigouos blocks
+may be present and an entrypoint in the code.
+
+ 1. a 7 character signature "B000FF\n" ( that is with 3 zeroes, and
+ ending in a linefeed )
+ 2. DWORD for image start
+ 3. DWORD for image length
+ 4. followd by several records of this format:
+ 1. DWORD with address where this block is to be flashed to
+ 2. DWORD with the length of this block
+ 3. DWORD with the 32 bit checksum of this block, in perl:
+ unpack("%32C*", $data);
+ 4. followed by <length> bytes of data
+ 5. the last record has address ZERO, in the length the entrypoint
+ into the rom, and ZERO as checksum.
+
+
+NOTE: The Gigabeat-S nk.bin contains 171 records, plus the EOF record.
+
+mknkboot.c appends two images:
+
+1) A "Disable" image which overwrites a word in the EBoot image
+2) Our bootloader image, which has the same load address as nk.exe
