I'd like my program to exit gracefully instead of crashing under
emulated environments, such as DOSBox, dosemu, Windows 98/SE console,
etc.  I'm having an especially difficult time detecting DOSBox.
What are the known techniques for doing this?

So far, I've looked at the results of 'mov cr0', 'smsw', and a
variety of Int 0x2f calls, such as 0x1600, 0x160A, 0x4680, 0x4010.
Of course, I don't have all possible environments where the code
could be executed, e.g., I can't test OS/2, Win 3.11, Win NT,
Win 95, etc.  So, compiled information on the expected results of
those calls or any other suggested calls or techniques would be
useful.
