title: Driver INF File: Identifying supported OS Architecture from driver inf file
body: <p>I am trying to parse INF file of drivers in my code to identify the OS architecture supported by them. For this I'm referring to the <strong>"INF MANUFACTURER SECTION"</strong> link:</p>
  
  <p><a href="http://msdn.microsoft.com/en-us/library/windows/hardware/ff547454(v=vs.85).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/hardware/ff547454(v=vs.85).aspx</a></p>
  
  <p>I have an Driver INF File which has a manufacturer section as:</p>
  
  <p>[Manufacturer]</p>
  
  <p>%HSD%=HSD,NTAMD64</p>
  
  <p>according to the manufacturer section documentation given in the above link, the INF Model Section name must be decorated with the supported architecture and hence, <strong>"NTAMD64"</strong> suggests that the Driver is valid for a 64-bit Windows Operating System. 
  But what does <strong>"HSD"</strong> suggest?</p>
  
  <p>Which operating system does it refer to? How to indentify this?</p>
