brand new dell latitude 3500

Joe Gill

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?

Thanks!

Cheers!

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).

@george1421

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:

Boot Options:
Onboard NIC (IPV4)

System Configuration:
Integrated NIC
Enable UEFI Network Stack
Enabled with PXE

SATA Operation:
AHCI

Secure Boot:
Enable Secure Boot
Audit Mode (I tried this doesn’t make a difference)

POST Behavior:
FAST Boot Thorough

Ah that’s it turn off secure boot because iPXE is not signed at all. So the firmware won’t load iPXE.

Joe Gill

@george1421

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.

@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
it works

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)

Ding ding ding ding! I need to set my dhcp server settings for UEFI!!! Thanks!!!

@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.

Lets first try to understand your problem so we can work on a solution.

Just for clarity PXEClient:Arch:00007:UNDI:003016 The 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?

bigjim

@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.

Thanks

@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 dhcp-boot=tag:UEFI,ipxe.efi,,10.5.0.240

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-prompt is 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)

@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)

dhcp-boot=tag:UEFI32,i386-efi/ipxe.efi,10.5.0.240

dhcp-boot=tag:UEFI,ipxe.efi,10.5.0.240

dhcp-boot=tag:UEFI64,ipxe.efi,10.5.0.240

The syntax tag: is no longer valid and needs to be replaced with net:

https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq#Install_dnsmasq_on_CentOS_7 for reference

It’s confusing because there’s info on both older versions of dnsmasq and the newer ones, but likely this is the cause.

Has anyone figured this out yet?

Sebastian Roth

@Mountainmanmoore What exactly do you mean be “this”???

Joe Gill

@Mountainmanmoore

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.

TheFunk35

Sorry to dig up an old post but I have a lot of 30 of these laptops that need imaging.

I get to the Fog menu, so I know my Windows DHCP server settings are okay, but the second I go to “Perform Quick Host Registration/Inventory” the server reports that bzImage loads and then immediately I receive an error that says Chainloading failed followed by the same message as the error posted here:

https://forums.fogproject.org/topic/12108/could-not-select-exec-format-error-http-ipxe-org-2e008081

I am using the laptop’s integrated ethernet NIC. In the laptop’s BIOS, the UEFI network stack is set to enabled w/PXE. The SATA controller is set to AHCI mode. Secure boot is disabled, as is the TPM and Absolute Guard.

It should be noted that I had previously tried the SATA controller in RAID ON mode and tried a registration previously and those attempts proceeded to boot the registration menu but failed to find a hard drive, so I switched the controller, did a clean install because Windows didn’t like that, and tried again.

george1421

@TheFunk35 What version of FOG, and is the firmware up to date on these 3500s?

TheFunk35

@george1421 Latest production version of Fog 1.5.8 running on CentOS 7. I don’t know about the firmware. I will try to update it tonight. I’m not hopeful that will help. It looks like my older Precision T3610 desktops are having a similar issue. They all reach the Fog menu but then trying to load anything from there is a no go.

george1421

@TheFunk35 For sure the computer is in uefi mode? And you are double sure that safeboot is disabled?

Just for grins what are you sending as a PXE boot file to this computer?

While I seriously doubt is an ipxe menu issue if you go to a browser and call up this url, this is the program behind the iPXE menu. http://<fog_server_ip>/fog/service/ipxe/boot.php post the results here.
