@FlorianLenz I did all these steps and it worked with normal USB adapters, but with USB-C-Ethernet adapters does not work, could you help me out?
(It could be important to know this type-c adapter have 1 HDMI port and 3 normal usb ports)

@sloeckle You can use an older kernel for now, but I’ll work on a fix for this issue. I don’t have access to the hardware needed to reproduce this issue. Are you willing to help us test some kernels?

I think I have the same problem and I want to be sure of exactly what I need to do (I don’t know if there is a step-by-step tutorial…).

I boot with a USB-C network adapter on an HP Elitebook. It finds FOG, I have the menu, I choose to deploy an image, and then I get this error message:

IMG_20251106_162705.jpg

Is this the problem in question?
If so, what exactly should I do? I see (link @FlorianLenz ) that I need to replace two files with the new ones, then run the .sh. But isn’t that dangerous for other network boots?

Thank you in advance for your help.

@phant0mbot said in Dell OptiPlex 3000 Thin Client:

have tried both SAN and GRUB exit options

boot loader == snponly.efi

These are in contradiction with each other. SAN boot and Grub are bios boot methods. snponly.efi is a uefi boot loader. Since you are getting into the fog iPXE menu we can assume the hardware IS uefi based since it is booting snp.efi. Try a uefi exit mode of rEFInd (refind) to see if that will boot from the hard drive. The default value can be set globally in the fog configuration->fog settings page. Don’t force a bios attempted boot from a uefi booted computer, that never works.

@Tom-Elliott thanks for the quick response. No joy though.

I’ve been and tried an Ubuntu live iso with a 6.14 kernel from the Ubuntu Concept Snapdragon Elite branch (https://discourse.ubuntu.com/t/faq-ubuntu-25-04-on-snapdragon-x-elite/61016) and even that doesn’t boot - though it gets as far as telling me it can’t create a device tree. So I guess I’m just going to have to be patient while upstream gets this whole SoC working.

@Tom-Elliott
Of course, it’s disabled. 😉

@rodluz Updating the kernel to the latest version helped; the computers are finally being restored at full and consistent speeds, for both unicast and multicast deployments. Thank you for your help.

Dear Tom,

Thanks, and this is what I figured. At least I can pxe boot it and capture the image now, if I switch it to “AHCI/NVMe” mode, and switch back to “RAID” mode to boot the single NVMe drive.

I made this known so we can reach out to Dell and possibly have this changed as it actually doesn’t need this “RAID” mode.

Also we still have to disable secure boot on any computer either HP or Dell to get the pxe boot to work.

We did manage to use FOG to capture a RAID from an HPE DL380 Proliant Gen10 RAID controller and use that to load Windows Server 2022 now, so it does seem the kernel is the issue here on this intel motherboard RAID.

Regards,

Matt

@george1421

thank you for your great answer. You are completely right, it is a 17-x104ng, not a fg. It was an error of me 🙂

The needed hardware id is VEN_10EC&DEV_8136

Hope that helps

Thx,

@Donutsrule5

OK lets see if we can boot from a usb drive. This tutorial will instruct you on how to build a usb boot image. https://forums.fogproject.org/post/69606 the google drive link below will take you to step 7 in the thread.

https://drive.google.com/file/d/1psCrPVzBTvlakLkCMvhdoScAEZp1CKE6/view?usp=drive_link

Once you build the usb boot drive, take the kernel and init.xz from your current version of fog and replace the ones on the flash drive with the ones in from the FOG server. The files are in /var/www/html/fog/service/ipxe directory.

Once you have the usb drive ready, pxe boot into the grub menu on the flash drive, then go into debug mode. After several pages of text you need to clear with the enter key you will be dropped at a fos linux command prompt. If you can get that far then fos linux is OK and the problem is probably with ipxe or the handoff between the two.

If you want to image with the flash drive, schedule the task in the fog server BEFORE you usb boot and select option 1 from the menu. If you get it out of sequence you will get an error that says something about Null. Basically its saying you don’t have a task scheduled on the fog server so there is nothing to do. Lets see if we can get it to boot this way.

@skyhawk3355 I remember awhile ago I needed to create a one-off kernel for a system that had a 486 cpu. I checked but I don’t have that kernel any more.

I just recompiled the linux 6.6.85 for a 586 based CPU. I can recompile for a 486, but I don’t know if that is going to get us anything better.

Here is 6.6.85 586 version
https://drive.google.com/file/d/1GAzFjbtpDVXXCRpe6bIZ5mwySSXeDHko/view?usp=drive_link

Here is 6.6.85 586 where I stripped out some drivers like scsi, nvme, uncommon network drivers, virtualization drivers, etc. I was able to strip out over 1MB of kernel size from the previous one above. Did I through out too much?? YMMV.

@Ced58 I use this model. It’s best to get either the official Lenovo usb c ethernet adapter or the proprietary Lenovo adapter for the special ethernet port on these. Also in the bios there’s a Mac pass through option that you want to set to internal or second Mac address. With the latest version of fog and kernel it should see that internal mac even if you share an adapter for imaging multiple of that device.

@rodluz said in Lenovo ThinkPad L14 Gen 5 - kernel panic:

@jflash Great! Did you use the default kernel from FOG after the update, or did you use the kernel from my repo?

I don’t try older kernel, just put new one 🙂

@pilipp_edv I had a very similar issue to this a while back but it was with an HP laptop. It turned out to be a hardware defect. I was able to get the motherboard replaced under warranty, so maybe you can too for this laptop.

Hello All! (Especially Wilsol)

I used the top configuration ideas from Wilsol, and before I could get through the entire list, darned thing started working. (yeah probably secure boot, thanks Tom for pointing us in the right direction)

Thanks to everyone for the assist.

@aurfalien If you are still on this quest. What we would need is the hardware id of this network adapter. You can get this from windows in the device manager. We would need the vend and device IDs.

If in linux then use lspci -nn to get the device IDs. They will be 2 sets of 4 character hex numbers within the square brackets separated by a colon. i.e. [8086:1b4e].

With that code we can see if there are standard linux kernel drivers for this network adapter.

I got this fixed.
i think they fixed it without me but i had an open ticket and was talking iPXE and swapping files and all sorts.

Anyway new firmware 1.21 now working.

@Nyeine I’ve got an Orin Nano at home and an AGX at work. I’m not sure you can image them with FOG. TBH I have never tried, so it would be interesting to find out.

One comment before I get too deep into this, if you use for your dhcp server either WIndows 2016 or later or linux as your dhcp server, you can setup profiles with your dhcp server to automatically send the right ipxe boot loader based on the pxe booting computer. You won’t need to mess with the ipxe.efi files like you have. You can surely continue to do it that way, I just wanted to let you know there might be an easier way to go about it.

So you are able to pxe boot into the iPXE boot loader, as soon as you pick a menu option that is where the wheels come off, so to say. Looking at the screen shot the process is failing at the handoff between ipxe and FOS Linux (arm_Image+arm_init). Its hard to tell if its ipxe or fos linux at fault.

I have a process to create a debug usb image for x64, but I haven’t tried to create one for arm. In theory if you have a working Jetson Orin running ubuntu you should be able to follow this to create a FOS linux usb boot image: https://forums.fogproject.org/topic/7727/building-usb-booting-fos-image In your case you don’t want to use bzImage and init.xy but use the arm_Imag… (to replace bzImage) and arm_init (to replace init.xz). The idea here is to see if you can select register from the grub menu to get FOS Linux to boot on the jetson nx. If it can then the issue is with ipxe. If it doesn’t hopefully you can debug with the usb boot image.

You may need to build a custom linux kernel for the Jetson. Just for reference https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/SD/Kernel/KernelCustomization.html

@yardk Okay, good news, bad news, so good news is the code loading the Arm architecture seems to be working correctly.

Bad news, we haven’t really had much time to troubleshoot against all potential arm devices and I believe this is a semi-known issue that we just haven’t been able to narrow down and/or fix at this point.

If you’re able, can you try loading a 6.1.22 arm kernel or maybe 6.1.89?

I suspect, and it’s just a sneaking suspicion, what you’re seeing is similar to the issue we’re seeing with hyper-v/proxmox and efi loading.
