title: What is the MZ signature in a PE file for?
body: <p>I'm working on a program that will parse a PE object for various pieces of information.</p>
  
  <p>Reading the specifications though, I cannot find out why the MZ bytes are there, as I cannot find this on the list of machine types that these 2 bytes are supposed to represent.</p>
  
  <p>Can anyone clarify?</p>
