       srec_msbin - Windows CE Binary Image Data Format

       This  format  is	 the  output  of the Microsoft WinCE Platform Builder.
       This is a binary	(non-text) file	format.	 File  names  in  this	format
       typically (ambiguously) use the .bin suffix.

   File	Format
       Files in	this format start with a header	record.

       Then comes the data itself, organized into records.

       The  file  finishes  with  an  execution	start address record.  This is

   File	Header Record
       Data in this format start with an optional header containing the	 magic
       "B000FF\n", followed by the image start (four bytes, little endian) ad-
       dress and the span of the image (highest	address	- lowest address +  1)
       (four bytes, little endian).  The file header does not have a checksum;
       it is therefore possible	that a corrupt file header will	go undetected.

       |Magic	   | Least	| Greatest   |
       |"B000FF\n" | Address	| Address    |
       |(7 bytes)  | (4	bytes)	| (4 bytes)  |
       There-is-no-provision-for+a-file-comment	of any kind.

   Data	Record
       Each record consists of a record	start address (four bytes, little  en-
       dian),  a  record length	(four bytes, little endian), a record checksum
       (four bytes, little endian), followed by	the  record  data.   The  data
       part of each record is raw byte values, no encoding.

       |Start	  | Length    |	Checksum  |   Data    |
       |address	  | (4 bytes) |	(4 bytes) |	      |
       |(4 bytes) |	      |		  |	      |
       The  checksum  is  calculated  by a simple sum of unsigned bytes	into a
       32-bit accumulator.

       The 12 record header bytes are not included in the record checksums; it
       is therefore possible that a corrupt record header will go undetected.

       It is not possible to place data	at address zero	with this format.  Ad-
       dress zero is reserved for use by the execution start address record.

       There is	effectively no limit on	the length of a	record	(2^32-1).   It
       is  not	uncommon for a MsBin file to contain records with sizes	in the
       tens of megabytes.

   Execution Start Address Record
       Last comes a special record with	the record address  set	 to  zero  and
       record  length  set to the image	execution start	address.  According to
       specification the record	describing the execution start address must be
       always present, and must	always be the last record in the file.

       |Zero	  | Start     |	Checksum  |
       |(4 bytes) | Address   |	= 0	  |
       |	  | (4 bytes) |	(4 bytes) |
       The  MsBin  files produced by SRecord are valid and can be successfully
       parsed by the command line utilities viewbin and	cvrtbin	(part of  Win-
       dows CE platform).

       For  a  MsBin  file to be usable	in Microsoft WinCE Platform Builder it
       has to contain a	TOC meta-structure.  This is data embedded in the file
       by Microsoft WinCE Platform Builder itself.

       The  opposite conversion	- from MsBin - comes in	handy when analyzing a
       MsBin file (i.e.	a WinCE	image).

   Size	Multiplier
       In general, binary data will expand in sized by approximately 1.0 times
       (approaching asymptotically from	above) when represented	with this for-
       mat, as the 15-byte file	header is  averaged  over  the	data  content.
       Holes in	the data will also increase the	size.
