@FOG38640 said in DHCP option 67:

Is there an option for FOG to automatically choose between BIOS and UEFI?

For what? For the network boot file?

If so that is done by your dhcp server. What is your dhcp server? (its been a few days so I don’t remember, a quick scan of the thread didn’t answer that question either)

Edit: found it way at the bottom Windows 2019 server. So there is instructions for windows 2012 and later. Hopefully it translates to 2019 dhcp servers. https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy
