This isn't a very long phase... and PXE will unfortunately only answer 
ARP while it is either sending or trying to receive a packet.  However, 
I find it extremely odd that you would see failure due to a window that 
usually amounts only a few milliseconds.  There are other delays which 
would seem much more severe.

PXELINUX, or perhaps better said, it's a known issue with PXE.
