Sending a PXE (Preboot eXecution Environment) Client message requires the use of DHCP Option fields. All PXE Client packets provide the same extended DHCP information in these options. This includes DHCP Request messages used to communicate with the server to which the PXE Client has been redirected. Other fields and options may be different between the packets, based on the standard DHCP protocol.
