      Oops I missed that at first glance, append is not a supported iPXE statement. You do need to use the imgargs statement instead.

      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!

        APPEND is a PXELinux option, not an iPXE option.

        Use the imgargs argument instead.

          at issue. FOG passes a number of kernel parameters to the FOS client engine. You can also use that method to ensure what you are entering in the webgui ends up correctly in the assembled iPXE menu.

          Thank you for the tip. I see there is no “imgargs” option too. Let me give a try.

          Thank you

            Thank you the “imgargs” also didn’t work. Trying without it.

              @csa You replaced APPEND with imgargs vmlinuz ?

                Ok I see a red flag here.

                What version of FOG are you running? What do you have set for dhcp option 67 {boot file}.

                And to refer to your OP. Why does the top one work WITH imgargs and the bottom one does not if you replace append with imgargs? The only thing I see in the top one is you are calling out the kernel with linux then adding in the args.

                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!

                  Team,
                  I tried all the following options but didn’t have any success. This is happening with any centos or RHEL distribution. With ubuntu “kernel, initrd and imgargs” are working like champ.
                  The issue seems to be unable to pass the following option through ipxe.
                  ramdisk_size=100000 ksdevice=eth0 root=/dev/rd/0 ip=dhcp
                  using imgargs or moving to initrd.

                  Option 1.

                  Error --> boots and complains on “ks=… No such file or directory”
                  Moved “ramdisk” before ks=. Errors out saying "ramdisk=100000… no such file or directory

                  :fog.centos
                  set path /fog/OS_IMAGES/CENTOS-6.8-DVD
                  set nfs_path /images/OS_IMAGES/CENTOS-6.8-DVD
                  kernel http://fogsrv/fog/OS_IMAGES/CENTOS-6.8-DVD/images/pxeboot/vmlinuz || read void
                  initrd http://fogsrv/fog/OS_IMAGES/CENTOS-6.8-DVD/images/pxeboot/initrd.img || read void
                  imgargs ks=http://fogsrv/fog/kickstarts/centos6.cfg ramdisk_size=100000 ksdevice=eth0 root=/dev/rd/0 ip=dhcp url --url http://10.0.28.24/fog/OS_IMAGES/CENTOS-6.8-DVD  || read void
                  boot || read void
                  goto start
                  

                  Option II
                  Removed imgargs section and moved everything to “initrd” section. Boots further but errors out saying " Cannot open root device "(null) … Please append a correct “root=” boot option ". Which means its the options in initrd section are getting ignored.

                  :fog.centos
                  set path /fog/OS_IMAGES/CENTOS-6.8-DVD
                  set nfs_path /images/OS_IMAGES/CENTOS-6.8-DVD
                  kernel http://fogsrv/fog/OS_IMAGES/CENTOS-6.8-DVD/images/pxeboot/vmlinuz || read void
                  initrd http://fogsrv/fog/OS_IMAGES/CENTOS-6.8-DVD/images/pxeboot/initrd.img ks=http://fogsrv/fog/kickstarts/centos6.cfg ramdisk_size=100000 ksdevice=eth0 root=/dev/rd/0 ip=dhcp || read void
                  boot || read void
                  goto start
                  

                  Thank you

                    @csa I believe you need to move it to the “kernel” section, not the initrd

                      Tom,
                      You are simply awesome. Yes moving all the options to kernel worked like a champ. So for RHEL / Centos the following ipxe configuration menu works

                      :fog.centos
                      set path /fog/OS_IMAGES/CENTOS-6.8-DVD
                      set nfs_path /images/OS_IMAGES/CENTOS-6.8-DVD
                      kernel http://fogsrv/fog/OS_IMAGES/CENTOS-6.8-DVD/images/pxeboot/vmlinuz ks=http://fogsrv/fog/kickstarts/centos6.cfg  ramdisk_size=100000 ksdevice=eth0 root=/dev/rd/0 ip=dhcp splash quiet – || read void
                      initrd http://fogsrv/fog/OS_IMAGES/CENTOS-6.8-DVD/images/pxeboot/initrd.img || read void
                      goto start
                      
                      

                      Thank you so much

                          @csa I think you could still use imgargs just call it before initrd. Glad it’s working though.

                            @Tom-Elliott I think he simply forgot to put vmlinuz after imgargs.

                              @Quazz I don’t think the kernel has to be specified as its the args but I could be wrong

                                @Tom-Elliott iPXE seems to claim it’s mandatory from what I can tell

                                http://ipxe.org/cmd/imgargs

                                But it does basically the same thing as what you said, so it doesn’t really matter.
