You could try Ghost 11.5 suite, but my feeling is that your reluctance to go to WinPE is just going to cause you additional problems as time passes and hardware becomes increasingly incompatible with DOS.
UEFI is not supported by any currently available version of Ghost, so this needs to be disabled or turned off if using Ghost.
However, re-reading your posting, I am not entirely clear at what point the PXE boot fails. Is it failing before you get to the point of loading the boot image? If so then this would suggest a fundamental issue with the DELL's ability to PXE boot (not unheard of). If it is pulling down the boot image, but the boot is not taking place, then it points to a driver issue in the boot image. Remember that DOS has no SATA support, and does not understand partitions > 2Tb.
