33  * Support for NFS diskless booting with BOOTP (RFC951, RFC1048)
85  * This implementation uses BOOTP (RFC951, RFC1048), and
88  * This method gets everything it needs with one BOOTP
90  * the old BOOTP functionality subset of DHCP.  It is not
91  * clear that DHCP provides any advantage over BOOTP for
98  * address for the client and support BOOTP.
