When booting a Dell Latitude 3450 to IPXE the laptop will contact the NBS server but when configuring net0 it gives the following error:
No configuration methods succeeded (http://ipxe.org/840ee186) PXE-E99: Unexpected error (6).
Deployment Solution 8.7.1273
Disabling DMA in the BIOS for both pre-boot and the OS resolved this issue.
Some OEM manufactures BIOS will not allow for machine to boot to PXE or iPXE
