Unfortunately that's the code which actually calls the underlying PXE 
stack.  Removing it will leave you with an undionly.kpxe binary which 
basically does nothing.

You could try undionly.kkpxe (which unloads less of the underlying stack 
before attempting to use it) or you could try ipxe.pxe (which includes 
all of the iPXE native drivers and so should work on all supported 
hardware).

For a start, you should simplify your test environment as much as 
possible.  Build an iPXE binary with no embedded script, certificates, 
etc., with the standard configuration.  Load it directly from the PXE 
ROM, bypassing pxelinux.
