@jmvela2x Well this thread has been going on for 5 days now and I’m not sure I’ve done a good job explaining how FOG works.
With DHCP Profiles setup with the same computer.
BIOS Computer -> BIOS PXE Boot -> undionly.kpxe will be sent to target computer -> the global value of FOG Settings value contained in [BOOT EXIT TYPE] will be used -> SANBOOT for its Exit mode
UEFI Computer -> UEFI PXE Boot -> ipxe.efi will be sent to target computer -> the global value of FOG Settings value contained in [EFI BOOT EXIT TYPE] will be used -> REFIND_EFI for its Exit mode
This process works 99.9% of the time. The oneoffs that you might find would be UEFI based computers with quirky firmware or hardware.
