@george1421 I used TCPDUMP without telling which ports to listen (tcpdump -i enp12s0 -w output3-BIOS-hp.pcap), in 3 computers:
UEFI Computer #1 - file is “output1-UEFI-insys.pcap” - https://drive.google.com/file/d/1lBxNv2bhjTtMhPEC2gd66tpzV3egZK5i/view?usp=sharing UEFI Computer #2 - file is “output1-UEFI-b560m.pcap” - https://drive.google.com/file/d/1TgiQS15RrESjc3Q92euB7UWOMLPOxXFu/view?usp=sharing BIOS Computer #3 - file is “output1-BIOS-hp.pcap” - https://drive.google.com/file/d/1gkz71TMr8XzJovDSOZqyvkcvtsjCz2I0/view?usp=sharingI think in these files, you can see at DHCP information and finally can figure out how to help me. I really need this to be working. School starts next tuesday and I have a lot of computers to deploy images to.
