      Oct 12 12:59:32 dureal99d-Precision-WorkStation-T5400 dnsmasq-dhcp[1280]: 3272245650 vendor class: PXEClient:Arch:00007:UNDI:003016

      That is what I see:

      Not ignoring you on this. The vendor class (option 60) doesn’t have anything that is unique to describe this machine. While the arch does tell you if it is a uefi or bios machine that is all that can be gleaned from that option. The UNDI part is only what version of UNDI the client supports. The Dell 6230 I had also had a undi value of 003 016 and that one used ipxe.efi or snp.efi for a uefi boot.

      The UUID (option 97) is suppose to be unique on a model (first half of uuid) and device (second half of uuid). on a per machine basis. My hope is that we can use the uuid for this. The only other thing that is unique in the dhcp request is the mac address, but then you will need a match filter for every mac address you want a unique iPXE boot kernel for. That (IMO) is not very sustainable if you have more than about 20 devices on your campus.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          Well that would be amazing. We should work on using that for ISC-DHCP too.

            It would be wonderful if all hardware manufacturers did this too. But as with the Lenovo the OP has, its all zeros. As long as that is model unique then we can work with it, but I suspect all lenovos have that set to zero.

            From what I understand isc-dhcp can do this too like dnsmasq make run time decisions based on what client advertises. I just haven’t dug into the isc-dhcp settings as of now to say for absolute.

              @george1421 According to rfc4578, Option 97 is one of the public DHCP options - meaning vendors can use it for whatever they want, including nothing. https://tools.ietf.org/html/rfc4578

              That’s why there isn’t a DHCP option for 97 listed in the ISC-DHCP manual:

                  @dureal99d For dnsmasq, George is the guy to ask. He’s laid out several matching techniques. If option 60 sent from the host doesn’t have something unique appended to the end of it, you’re probably out of luck - unless you want to do it the insane-hard way and use MAC address matching.

                    I don’t mind using mac address matching. or rather learning it and then using when needed.

                      @dureal99d well then you know the basics then you probably want to look into this filter

                      dhcp-mac=set:mac_01,<mac_to_match>

                      so then you will need a dhcp-boot with the conditional test for mac_01 and the name of the boot file you want to send.

                        @dureal99d I’ve been on dnsmasq’s mailing list for about a year now. Simon Kelly - creator and maintainer of dnsmasq - sends out an email with answers to questions about every day or every other day. You can get on this mailing list, and you can email him questions like I have, and he’ll respond. As with anything, include as many details as possible. The link to the mailing list and such is below.

                              You’ve tagged a specific MAC as Simon did in his answer, then later assigned that tag a specific file. Looks good to me.

                                        @dureal99d I would say this line is important

                                        dnsmasq-dhcp[1283]: 1735601825 tags: BC_UEFI, r503u, enp8s0

                                        This tells me that you have the match mac address right because there is the r503u tag. To prove it change the mac address slightly and than pxe boot again. That tag should disappear. (Don’t forget to change it back because this part IS working)

                                        So the dhcp-boot section is failing to match for us. This is just me guessing but change

                                        #this line
dhcp-boot=net:r503u,intel7156.efi,,192.68.1.109

#to this
dhcp-boot=tag:r503u,intel7156.efi,,192.68.1.109
