True, but Intel's PXE spec expects it to fetch the instructions from the 
TFTP server, and get all the details about what to fetch via DHCP. To do 
the "LoJack" trickery would require a very custom BIOS .. one that a 
laptop manafacturer would be pretty unlikley to provide to a software 
vendor, IMHO.
