Dell Latitude 3120 no Legacy boot
-
Legacy boot not an option on new Dell Latitude 3120s. When connected Boot Menu only shows USB NIC (ipv4) and USB NIC (ipv6). Is there an option to boot USB from FOG?

@garydfrady You need to send dhcp option 67 of ipxe.efi or snp.efi to boot a uefi based computer. For the latest hardware support you need to update the FOS Linux kenrel (Web ui ->FOG Configuration -> Kernel update) Update both the x32 and x64 versions to 5.15.x or later.
You will probably need to update ipxe to the latest version if you are on FOG 1.5.9 then you can follow this process: https://forums.fogproject.org/topic/15826/updating-compiling-the-latest-version-of-ipxe
Lastly in the uefi firmware on the dell you need to make 2 modifications.
- Disable secure boot
- Set the disk mode from raid-on to ahci mode.
Once you’ve done everything then the system should pxe boot.

@george1421 Where do we need to send option 67 if ipxe.efi or smp.efi?

@george1421 Attempting to update the ipxe version. When booting to usb nic ipv4, no build code is listed. Is this because we are using the usb nic (dongle) to hardwire the laptop to the network?

Not sure I fully understand the question but for pxe booting your dhcp server (what ever that is) should have settings for dhcp option 66 (next-server) and 67 (boot-file). That boot file needs to be ipxe.efi or undionly.kpxe depending on what target computer is pxe booting.
So lets start out with what device is the dhcp server that is being used for this network? Are you using the fog server on a dedicated imaging network or are you using your campus dhcp server?

This statement also confuses me. You are using a usb dongle. That is OK. Does that dongle PXE boot? If you use the F12 boot manager while the dell is booting is IPv4 listed for PXE booting? If no then you must used a Dell certified usb dongle to pxe boot.

@george1421 We are using Dell Certified dongles.

Then I guess I don’t understand the above statement? What does no build code listed mean?
Do you have a clear picture of what’s not working taken with a mobile phone? -
@george1421 WE GOT IT! Thanks for your help!
