      @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.

          based upon what i read this config should work right?

          this config should work right?

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

              yet the file I’m telling it to send is not being sent, something is off.

                @Wayne-Workman @george1421 has this line as dhcp-mac=set:mac_01,<mac_to_match> perhaps i need to add the =set part. i only took it away because of what simon says in his article

                      @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

                      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!

                              @dureal99d I think I can explain this (understand I’m still learning dnsmasq’s insides too.).

                              dhcp-mac=set:r503u,50:46:5d:98:6f:3c

dhcp-boot=net:IA32_UEFI,i386-efi/ipxe.efi,,192.168.1.109
dhcp-boot=net:BC_UEFI,ipxe.efi,,192.168.1.109
dhcp-boot=net:X86-64_EFI,ipxe.efi,,192.168.1.109
dhcp-boot=tag:r503u,intel7156.efi,,192.68.1.109

                              We had a discussion when we were setting up the initial test. if you look at the tag:r503u line. What is matching there?? Look its the mac address so the only condition you have is that the mac address has to be X. So every time dnsmasq see mac address X it will send out intel7156.efi.

                              Now why in efi mode?? This one has me a bit stumped. Logic would say first match wins, in that case this line would be the first match.

                              dhcp-boot=net:BC_UEFI,ipxe.efi,,192.168.1.109

                              So that would explain why ipxe.efi is being sent because the only test here is it be in efi mode.
                              But in my testing I was seeing that the last match was winning. So if that thought is true. This one should be the winning line.

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

                                @george1421 said in Serve different types of .efi boot files:

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

                                You might want to update that line to something like this

                                dhcp-boot=tag:BC_UEFI,tag:r503u,intel7156.efi,,192.68.1.109

                                That will create an AND condition. So it has to be in uefi mode AND the mac address has to match.

                                  @george1421 its back to sending the ipxe.efi. I wondwer what could it be. clearly its something right under the nose.

                                    @dureal99d change up the order put the

                                    dhcp-boot=tag:BC_UEFI,tag:r503u,intel7156.efi,,192.68.1.109

                                    before the one with ipxe.efi. (just guessing)
