You cannot just disable BOOTP because DHCP is infact an extension to
BOOTP. Here is the absrtact from RFC2131

Abstract

   The Dynamic Host Configuration Protocol (DHCP) provides a framework
   for passing configuration information to hosts on a TCPIP network.
   DHCP is based on the Bootstrap Protocol (BOOTP) [7], adding the
   capability of automatic allocation of reusable network addresses and
   additional configuration options [19].  DHCP captures the behavior of
   BOOTP relay agents [7, 21], and DHCP participants can interoperate
   with BOOTP participants [9].
