      @Tom-Elliott It does. At least it did in my environment when I was fighting with it. Getting close to being able to revisit this subject myself. Expect to be migrating our DHCP servers to WinSrv 2012R2 in the next 30 days.

          @need2 @Tom-Elliott well that complicates things… why did it work for me then? gah. I really need to sit down and tackle this.

          @Killklli Run the below commands and then try the attached script.

          ln -s /tftpboot/ipxe.efi /tftpboot/ipxe.efi.0
          ln -s /tftpboot/ipxe.efi /tftpboot/ipxe.0
          ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.kpxe.0
          ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.0
          
          port=0
          log-dhcp
          tftp-root=/tftpboot
          dhcp-option=17,/images
          dhcp-no-override
          
          
          #this line is suspicious to me. What the heck does 6,2b mean ?
          dhcp-option=vendor:PXEClient,6,2b
          
          #Here, I define netboot types
          dhcp-vendorclass=BIOS,PXEClient:Arch:00006
          dhcp-vendorclass=UEFI,PXEClient:Arch:00007
          
          #Set bootfile names depending on the client vendor identifier
          dhcp-boot=BIOS,undionly.kpxe
          dhcp-boot=UEFI,ipxe.efi
          
          pxe-prompt="Press F8 for boot menu", 3
          pxe-service=X86PC, “BIOS and LEGACY Network Boot”, undionly
          pxe-service=X86PC, “UEFI Network Boot”, ipxe
          dhcp-range=x.x.x.x,proxy

            @Wayne-Workman Hmmmm. UEFI still isn’t grabbing. But Legacy still is.

              @Killklli I just tested on my system - all I had was failure with using symbolic links.

              So - lets get rid of those and just use copies:

              rm -f /tftpboot/undionly.kkpxe.0
              rm -f /tftpboot/undionly.0
              rm -f /tftpboot/ipxe.efi.0
              rm -f /tftpboot/ipxe.0
              cp /tftpboot/undionly.kkpxe /tftpboot/undionly.0
              cp /tftpboot/ipxe.efi /tftpboot/ipxe.0
              

              Please stand by, I’m testing the code I gave you (it’s been a long day).

                @Killklli Try this, I just confirmed it works with LEGACY, have a great feeling about UEFI also.

                @Developers @Moderators Just making sure you guys see this.

                #port=0
                log-dhcp
                tftp-root=/tftpboot
                dhcp-option=17,/images
                dhcp-no-override
                
                #Here, I define netboot types
                dhcp-vendorclass=BIOS,PXEClient:Arch:00006
                dhcp-vendorclass=UEFI,PXEClient:Arch:00007
                
                #Set bootfile names depending on the client vendor identifier
                dhcp-boot=net:BIOS,192.168.1.2,undionly.0
                dhcp-boot=net:UEFI,192.168.1.2,ipxe.0
                
                pxe-prompt="Press F8 for boot menu", 3
                pxe-service=X86PC, “BIOS and LEGACY Network Boot”, BIOS
                pxe-service=X86PC, “UEFI Network Boot”, UEFI
                dhcp-range=192.168.1.2,proxy

                  @Wayne-Workman I’m still confused that for whatever reason I’m not even seeing the UEFI boot grabbing IP’s. I just get a server timeout.

                    @Killklli try this - beyond this, I need some shut eye and I need to bring home my work laptop which is UEFI capable.

                    log-dhcp
                    tftp-root=/tftpboot
                    dhcp-boot=undionly.0,10.0.0.3,10.0.0.3
                    dhcp-option=17,/images
                    dhcp-option=vendor:PXEClient,6,2b
                    dhcp-no-override
                    pxe-prompt="Press F8 for boot menu", 3
                    pxe-service=X86PC, “Network Boot using undionly.0”, undionly
                    pxe-service=X86-64_EFI, "Network boot using ipxe.0", ipxe
                    dhcp-range=10.0.0.3,proxy
                    
                    
                    #for pxe-service=    the known types are below.
                    #x86PC, PC98, IA64_EFI, Alpha, Arc_x86, Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI

                      @Wayne-Workman Just for when you get back to this. It still didn’t work. Still getting PXE-E18: Server Response Timeout for UEFI machines. But Legacy Works.

                        @Killklli Another thing I learned last night about dnsmasq

                        is…

                        You can only have one config file in /etc/dnsmasq.d/ and the names of the files in there do not matter - the daemon will read all of them and use them as config files if it can.

                        because the configuration file here: /etc/dnsmasq.conf does not specify a name, it just specifies a directory to look in.

                        So if you have a backup config file inside of /etc/dnsmasq.d/ you have to move that file elsewhere because it will interfere with dnsmasq.

                          @Killklli Are you still working on this? I have done a lot of testing and I am pretty sure that dnsmasq is not able to boot most UEFI devices as it uses DHCP option 43 which they don’t like (see here: https://www.mail-archive.com/dnsmasq-discuss@lists.thekelleys.org.uk/msg09233.html). I am working on a node.js proxy DHCP to support BIOS/UEFI and Mac OS X. But will be still a while I suppose - BIOS works pretty good and UEFI is not far either but the code is still a big mess.
