    @mjaskowski That’s kind of strange as the firmware should be downloaded by the build.sh script for you - see here. Please run ls -al fos/kernelsourcex64/linux-firmware and post output here. If you get no such file or directory run as suggested by George:

    cd fos/kernelsourcex64/
    git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
    

    Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

    Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

      running ls -al fos/kernelsourcex64/linux-firmware resulted in ls: cannot access fos/kernelsourcex64/linux-firmware: No such file or directory there is however a fos/kernelsourcex64/firmware directory

        This is not the same as fos/kernelsourcex64/linux-firmware. You need both!

          @mjaskowski Did you get to compile the kernel yet?

            I got pulled off this project and just back to it now. So I just updated to Kernel to bzImage Version: 4.19.48 and when I pxe boot to it I only get as far as rEFInd - Booting OS in a blue bar at the top of the screen and below prints:

            Starting bootmgfw.efi
            Using load options ’ ’

            and that’s all folks. What next?

              @mjaskowski Great to see you back. When you see rEFInd that means your client chainloaded to boot from disk. Make sure it is registered and a task is scheduled for it.

                I’m looking at https://wiki.fogproject.org/wiki/index.php/Building_a_Custom_Kernel and it’s not clear to me where I’m to perform step 1:
                Build Process

                • Install [WHERE?] the required packages to build the kernel with:
                  RHEL/Fedora/CentOS/.rpm other: (need confirmation that this is all the packages required?!?, may also need qt-devel and a few others)
                  yum groupinstall “Development Tools”
                • Ubuntu/Debian/.deb other:
                  sudo apt-get install qt3-dev-tools libqt3-mt-dev

                  @mjaskowski From the things you wrote weeks ago I though you where way beyond that point already. The development tools are needed to compile the kernel from source code. You install those on a machine you want to use for playing with the kernel build. You can use your FOG server for this but any other Linux machine will do just as well. Doesn’t really matter.

                    That’s the thing, I never get to the FOG menu options including the Quick Registration and all. I’ve previously tried to manually register and perform a task to no avail but I’ll try that again.

                            @mjaskowski Hmmm, that’s interesting. In the output you posted I counted “Text output” 17 times. Now when I look at the code you posted it also has 17 lines of “Text output”. What that means is that it gets as far as the last “Text output”. That’s really good news because on most systems we debugged this we only got as far as setup_efi_pci…

                            Ok, please add another efi_printk after the exit_boot call and check - see code here: https://elixir.bootlin.com/linux/v4.19.48/source/arch/x86/boot/compressed/eboot.c#L841

                            Best if you make it a different text, e.g. “After exit_boot” so we don’t have to count the outputs.

                            Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                              @Sebastian-Roth said in Lenovo 300e ipxe boots ok but ipxe.efi can't resolve the system:

                              @mjaskowski Hmmm, that’s interesting. In the output you posted I counted “Text output” 17 times. Now when I look at the code you posted it also has 17 lines of “Text output”. What that means is that it gets as far as the last “Text output”. That’s really good news because on most systems we debugged this we only got as far as setup_efi_pci…

                              Ok, please add another efi_printk after the exit_boot call and check - see code here: https://elixir.bootlin.com/linux/v4.19.48/source/arch/x86/boot/compressed/eboot.c#L841

                              So not even the ‘Exit boot 1’ prints

                                  efi_printk(sys_table, "Text output 17\n");

                                          hdr->code32_start = bzimage_addr;
                                  }
                              
                                  status = exit_boot(boot_params, handle);

                                @mjaskowski Ok, seems like it actually hangs on the exit_boot call. Doing a bit of research on this I found that we have another Lenovo device that does the same thing: https://forums.fogproject.org/topic/11060/debugging-lenovo-ideapad-miix-310

                                Doesn’t help much but let’s keep that in mind.

                                Ok, now we need to step into the exit_boot function, starting in line 704. Add those print statements here as well to see which call is the last.

                                  The last print I get is Exit boot 3

                                      status = allocate_e820(boot_params, &e820ext, &e820ext_size);

                                    @mjaskowski Ok, I think we are down to the bones of this. Now we have to take one step back and also enable iPXE debugging to see what happens when the kernel quickly returns control to the UEFI firmware before it takes over for the rest of the boot process.

                                    Please leave all the kernel source code as you have it right now as we might need to get back to that to implement a fix at some point.

                                    Take a look at what is needed to compile iPXE here: https://wiki.fogproject.org/wiki/index.php?title=IPXE#Compile

                                    Beside the prerequisites you only need the following commands:

                                    git clone git://git.ipxe.org/ipxe.git ipxe-efi
                                    cd ipxe-efi/src/config
                                    rm console.h general.h settings.h
                                    wget -O console.h "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/config/console.h"
                                    wget -O general.h "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/config/general.h"
                                    wget -O settings.h "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/config/settings.h"
                                    cd ..
                                    wget -O ipxescript "https://github.com/FOGProject/fogproject/raw/master/src/ipxe/src-efi/ipxescript"
                                    make bin-x86_64-efi/ipxe.efi EMBED=ipxescript DEBUG=efi_wrap
                                    

                                    Then install the new iPXE binary:

                                    sudo -i
                                    mv /tftpboot/ipxe.efi /tftpboot/ipxe.efi.orig
                                    cp path/to/ipxe-efi/src/bin-x86_64-efi/ipxe.efi /tftpboot/ipxe.efi
                                    

                                    Boot the machine and you should get some very funky colored output on screen (for example see here). Please take pictures of the output you get on the screen and post here. We need all the details you see!
