I played with this as recently as December. The BTX halted problem you 
are seeing is the same 'ol same 'ol 'BTX wants to play in vm86 mode, but 
BIOS or expansion ROM wants to play in real mode' problem.

Etherboot's PXE implementation tries to enter protected mode. At least 
with Etherboot, one can actually read the source and see this for onesself.
