@wass Since all of the boot loaders you mentioned are bios boot loaders and you are seeing the no configuration methods succeeded it sounds like the computer is in bios mode. Its strange that iPXE and bios mode computers are not able to configure the interface. For bios the boot loaders undionly.kpxe or ipxe.kpxe should work on 99.8% of all computers. Does this computer have multiple nic cards?

@george1421 @Tom-Elliott
thank you for your answers.

@george1421 i try your solution and is start ! thank you

@wass This is 100% supported and the recommended way to use fog. One thing you need to do for sure is disable secure boot on the machine as the ipxe bootfile isn’t a signed boot file (it hopefully will be in the not too distant future).

The other important step is setting up your dhcp server to point to fog by setting option 66/67 on your dhcp server, see also https://docs.fogproject.org/en/latest/installation/network-setup/

If there’s a more specific part of the setup you need help with we’ll happily guide you through it
