@smazzola Well a question back to you is, what is your dhcp server? What is the manufacturer and model of the dhcp server. If its a linux or windows dhcp server then you are in luck. Here is a tutorial on how to create a dynamic dhcp server that will send the proper boot file based on the pxe booting computer. https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence
