Sourcer is a commercial program, for disassembling x86 binaries (EXE, NE and PE).
Sourcer 8.0, includes the BIOS Preprocessor and Windows Source (which were separate products earlier).
Sourcer does a good job at automatically detecting code and data fragments.
More information can be found on their
web page.
Used together with Windows Source it produces lots and lots of additional information. Windows Source can extract information from .SYM, Codeview or .DBG files; there is full codeview support.
