The device is a Lenovo X1 Yoga Gen 2.
There are no other devices on the subnet. I have the server physically and logically separated from all other networks/devices in my scheme. I will disable secure boot and report back.
EDIT: Secure boot disabled is letting me boot to the FOG menu now. I just need to change the MENU EXIT TYPE I think. When I chose the Boot From Hard Disk option, I got a “Chainloading” failure. I think once I get that straightened out, it will work.
EDIT 2: I changed the option
REFIND_EFI and it was able to boot successfully from the FOG Menu.
