Do you have this area in 1.2.0 ?
FOG Configuration -> iPXE Boot Menu -> Exit to Hard Drive Type

If so, play around with that setting. Not every type is supported by every machine. The default is normally Sanboot style.

Actually, that was a good recommendation, when I changed it in the FOG admin/config http interface. Helped for some for sure! Thx
