Use of PXE Option 61 During the DHCP Discover Process
Many currently deployed Preboot Execution Environment (PXE) solutions are experiencing compatibility issues when using option 61 in the Intel® Boot Agent. Starting with GbE version 1.5.50 and 10 GbE version 2.3.19, the option is discontinued. Because of the compatibility issues, option 61 is not being reinstated in future releases.
