143 kernel heuristically recognizes these packets, a more general mechanism
144 for doing so should be provided.
148 uses a multicast address when first trying to locate boot
149 servers. While the Ethernet [sic] board is programmed to recognize
150 this particular multicast address (9:0:9:0:0:4), a more general
151 mechanism for doing so should be provided.
