Each "section" is preceded by a 5 byte preamble that starts with 00h. 
The next two bytes are the length and the final two bytes are the load 
address. Then, of course, the contents of the section follows.

After the final "section", you get a postamble which starts with FFh. 
The next two bytes don't matter. The final two bytes are the execution 
address.

There can be any number of "sections". As soon as LOADM encounters a 
postamble, it stops reading the file, even if there's more stuff after it.
