This really sounds like your PXE stack is broken.
pxechain uses a hack to pass the new boot path to the next NBP which may 
not work with all PXE stacks, but it shouldn't just hang and fail to load 
the next PXE stack at all.  Give me a couple of days and I will try to get 
you a version I've been working on with an alternate loader method that may 
work better for you.
