title: PXE Boot Arch Field DHCP Option 93
body: <p>The PXE Specification (<a href="http://www.pix.net/software/pxeboot/archive/pxespec.pdf" rel="nofollow noreferrer">http://www.pix.net/software/pxeboot/archive/pxespec.pdf</a>) specifies the following values for the client system architecture of the DHCP</p>
  
  <pre><code>0 = IA x86 PC(2)
  1 = NEC/PC98(2)
  2 = IA64 PC.(2)
  3 = DEC Alpha (2)
  4 = ArcX86 (2)
  5 = Intel Lean Client (2)
  </code></pre>
  
  <p>While the list looks a bit dated, what do modern Architectures use for the Arch Field.</p>
  
  <p>e.g. If I have a ARM Server or a RISC-V server and want to perform a PXE Boot what value should I provide for the ARCH Field?</p>
