Dell 7000 series laptops pxe booting

[Sebastian Roth]

@The-Dealman Which PXE boot file do you use? undionly.kkpxe or ipxe.efi?

[The Dealman]

@Sebastian-Roth I used the undionly.kpxe file. Should i be using the ipxe.efi? I never used that one.

ipxe.efi

for uefi based systems

[The Dealman]

@george1421 Okay. I will give that a try today and report back the results.

[The Dealman]

@george1421 I tried the ipxe.efi file and that didn’t seem to work either. I have included the screen shot below

[george1421]

@The-Dealman Well yes and no. It does work because its in ipxe and it detected a network and has an IP address.

Now the blanked out IP address in the picture. Is that your FOG server’s IP address?

[The Dealman]

@george1421 Yes that would have been the IP of the FOG server so it sort of worked but timed out.

[george1421]

@The-Dealman So two things.

1. Is the fog server on the same subnet as the target computer?
2. If you hit s on that error screen you will be dropped to an iPXE command prompt. Can you ping that address from the pxe booted computer? What happens if you wait for 30 second does the ping success this time?
3. ifstat from the iPXE console should show you the IP address of the pxe booted computer is that address consistent with what you expect? Can you ping that address from the fog server?

[The Dealman]

@george1421 Yes the FOG server is on the same subnet as the target computer. When i hit the S at the iPXE command prompt after the time out i did get to the command prompt. I pinged the ip of the FOG server and i get connection time out over and over again

ifstat

Here is a screen shot of the ifstat results from the client computer

@The-Dealman ok while sitting at that ipxe command prompt, key in dhcp net0 and see if it picks up an IP address. It looks like the interface doesn’t have an IP address.

[The Dealman]

@george1421 I ran the dhcp net0 command and i saw a bunch of … then it said ok. So i did ran a ifstat again and it show the same result as the below screen shot. Should i see the assigned ip in the ifstat results?

@The-Dealman Just to confirm this is a dell 7000 using the built in network interface (or via a port replicator)?

From a functioning windows system of this type, can you tell me the vendor ID and device ID of this network adapter? You can see this in the device manager -> <network device> -> Properties -> hardware IDs.

There is something on on here that I don’t understand. The 7220 should get an IP address here.

[sidebar] What we did by waiting 30 seconds and then attempting to pull a dhcp address is to test to see if spanning tree was blocking the target computer from getting an IP address. 30 seconds is long enough for standard spanning tree to start forwarding data.

[The Dealman]

@george1421 No spanning tree enable on this network. Here is the Hardware ID info

@The-Dealman Is that the usb-c to ethernet dongle?

[The Dealman]

@george1421 Yes it is usb-c. It’s one of these https://www.dell.com/en-us/work/shop/dell-docking-station-wd19-180w/apd/210-ariq/pc-accessories

[george1421]

@The-Dealman ok its a wd19. I know those work with a 7400. I have one of those in front of me now (both wd19 and 7400), let me look at the bios settings. now.

[george1421]

@george1421 In the 7400 firmware System Configuration->Thunderbolt configuration

Thunderbolt: Checked
Enable Thunderbolt Boot: checked
No Security: Checked

Secure boot->Secure boot: disabled

General ->Advanced boot options -> enable uefi network stack: enabled.

These are probably right because you are getting into ipxe. I’m going to pxe boot using this dock to see if I can duplicate the same error you see.

[george1421]

@The-Dealman on a 7400 using a wd19 it pxe boots right into the FOG ipxe menu. So what’s unique about your installation?

Is this a new FOG installation where you have never pxe booted into the iPXE menu before? OR is this the first uefi system you are tying to image?

[The Dealman]

@george1421 Yes your settings match what i have
