brand new dell latitude 3500
seems that the newest kernel finds no hard drive - these things are brand new, they are fresh off the line from dell.
anything I can do to see if its a hardware compatibility problem or something different?
these don’t have ‘legacy’ boot mode anymore - its all uefi.
If by this you mean booting a Dell Latitude 3500 via UEFI, I was able to get that going by setting up my DHCP server correctly as indicated in the post here.
@Mountainmanmoore What exactly do you mean be “this”???
Has anyone figured this out yet?
@bigjim Your dnsmasq config is outdated if you’re using the a newer version. (and UEFI + BIOS proxydhcp didn’t work at all on older versions)
tag:is no longer valid and needs to be replaced with
It’s confusing because there’s info on both older versions of dnsmasq and the newer ones, but likely this is the cause.
@bigjim If we look at the boot table map these are the different classes of systems
Type Architecture Name ---- ----------------- 0 Intel x86PC 1 NEC/PC98 2 EFI Itanium 3 DEC Alpha 4 Arc x86 5 Intel Lean Client 6 EFI IA32 7 EFI BC (EFI Byte Code) 8 EFI Xscale 9 EFI x86-64
For this device Arch:0007 should have matched, which is EFI_BC so the flag UEFI should be set.
So the boot file name should match
The following section has noting to do with the tags above because this is the boot menu, but its needed to boot correctly with some firmware.
pxe-prompt="Booting FOG Client", 1 # The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86, # Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI # This option is first and will be the default if there is no input from the user. pxe-service=X86PC, "Boot to FOG", undionly.kpxe pxe-service=X86-64_EFI, "Boot to FOG UEFI", ipxe.efi pxe-service=BC_EFI, "Boot to FOG UEFI PXE-BC", ipxe.efi
In this menu BC_EFI flag should match, because this is an internal variable. The
pxe-promptis set to 1 second because there is nothing for the user to select here because dnsmasq picks the correct flag.
Now I might suggest that you remove the comment at the end of hte BC line
pxe-service=BC_EFI, "Boot to FOG UEFI PXE-BC", ipxe.efi #ipxe7156.efi
Now there is one more trick if you have really wacky uefi firmware. Where you append the IP address of your fog server to the end of the pxe-service line making.
pxe-service=X86-64_EFI, "Boot to FOG UEFI", ipxe.efi, 10.5.0.240
But I haven’t see this extra trick needed in quite a while.
All this does is send the correct boot file name to the target computer using proxyDHCP protocol (over udp port 4011)
@george1421 Thanks for the response. Before I added PXEClient:Arch:00007:UNDI:003016 to the conf the laptop showed the
Boot to FOG UEFI PXE-BC
on the screen
but iPXE would never start as if it was not finding the file.
The screen goes away too fast to see if there are any other messages
You are correct 7156 was removed, I pulled it from an old build to try different options.
When i look in the dnsmasq log it shows the vendorclass as PXEClient:Arch:00007:UNDI:003016
Lets first try to understand your problem so we can work on a solution.
Just for clarity
PXEClient:Arch:00007:UNDI:003016The undi part is not unique to identify the hardware, that is only the undi version 3.16 which is not a unique identifier. I’m going to say the issue is that both tags UEFI and UEFIBC will match, then when you get down to the dhcp-boot section, the UEFI will match first and then not check the remainder (guess) so only ipxe.efi will be sent to the client. Also thing to note, unless you have an old version of FOG, ipxe71567.efi should no longer be supported. I’d have to check but that boot loader should have been removed from the build.
What isn’t working at the moment here?
@p4cm4n I have the same problem you had. When i look in the dnsmasq log it shows the vendorclass as PXEClient:Arch:00007:UNDI:003016
so i created dhcp-vendorclass=UEFIBC,PXEClient:Arch:00007:UNDI:003016
iwith that in the ltsp.conf i get the Boot to FOG UEFI PXE-BC prompt but it never boots the efi
here is my conf file.
If anyone could help it would be appreciated.

Ding ding ding ding! I need to set my dhcp server settings for UEFI!!!
Ding ding ding ding! I need to set my dhcp server settings for UEFI!!! Thanks!!!
@Joe-Gill i successfully ran through a pallet of these - 27 - and no issues. this was my process:
boot into BIOS setup.
Click enable UEFI network stack, scroll down to AHCI and click it. hit Apply.
on the left, select secure boot. disable using checkbox - it will ask if you’re sure. hit yes, hit apply. hit exit.
it reboots, hit f12, network boot ipv4
if it doesn’t work for you, make sure your ipv4 UEFI boot settings are setup on your dhcp server (ipxe.efi instead of undionly.kpxe)
I just tried it with the Secure Boot off and it failed the same way it did before.
It never even begins to load the iPXE.
I have secure boot enabled.
Ah that’s it turn off secure boot because iPXE is not signed at all. So the firmware won’t load iPXE.
The BIOS says:
Downloading NBP file... NBP file downloaded successfully.
Than it returns to starting to load Windows. I never see a FOG PXE boot screen at all. I’m running the 4.19.48 32 and 64 Kernel Versions. I have secure boot enabled.
I have the following enabled in UEFI:
Onboard NIC (IPV4)
Enable UEFI Network Stack
Enabled with PXE
Enable Secure Boot
Audit Mode (I tried this doesn’t make a difference)
FAST Boot Thorough
I can’t get it to PXE using UEFI
What doesn’t it do? What errors are you seeing?
You have to give us a bit more detail more that it doesn’t work (my words).
Did you manage to get this figured out? My coworker ordered a pile of these and I can’t get it to PXE using UEFI… Any advice there?
THANK YOU @Sebastian-Roth
just got a pallet of 67 of these and would hate to go back to pre-fog days…:)
@p4cm4n Most probably some kind of Intel software RAID foo. See if you can change from RAID to AHCI somewhere in the UEFI firmware settings.
