I am not sure if this is an issue that can be solved in iPXE but I will talk to the developers to see if they can help.
Argh! Thanks for all your help on this. I’ll see about getting Lenovo developers to cooperate or return their products.

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!

@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…
In doing the prerequisites I have the following roadblock:
[root@MCS-FOG ipxe]# git clone git://git.ipxe.org/ipxe.git ipxe-bios
Cloning into ‘ipxe-bios’…
fatal: unable to connect to git.ipxe.org:
git.ipxe.org[0: 212.13.204.60]: errno=Connection timed out
git.ipxe.org[1: 2001:ba8:0:1d4::6950:5845]: errno=Network is unreachable

@mjaskowski Ok, seems like it actually hangs on the
exit_bootcall. 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-310Doesn’t help much but let’s keep that in mind.
Ok, now we need to step into the
exit_bootfunction, 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);
if (status != EFI_SUCCESS)
return status;
efi_printk(sys_table, "Exit boot 3\n");
/* Might as well exit boot services now */
status = efi_exit_boot_services(sys_table, handle, &map, &priv,
exit_boot_func);
efi_printk(sys_table, "Exit boot a\n");
if (status != EFI_SUCCESS)
return status;
efi_printk(sys_table, "Exit boot 4\n");
@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_printkafter theexit_bootcall and check - see code here: https://elixir.bootlin.com/linux/v4.19.48/source/arch/x86/boot/compressed/eboot.c#L841Best if you make it a different text, e.g. “After exit_boot” so we don’t have to count the outputs.
So not even the ‘Exit boot 1’ prints

@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.
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.
So I get the following:
Succeed to download NBP file.

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
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:

and that’s all folks. What next?
