6. Host bootp / NFS setup¶
  R0P7785LC0011RL requires bootp and NFS capablities on host machine .

6.1 /etc/dhcpd.conf (Fedora 8 sample)

	ddns-update-style ad-hoc;
	default-lease-time 600;
	max-lease-time 7200;
	log-facility local7;
	option domain-name-servers 192.168.10.230;
	next-server	192.168.10.30;

	server-identifier 192.168.10.30;

	allow booting;
	allow bootp;

	subnet 192.168.10.0 netmask 255.255.255.0{
	}

	host r0p7785 {
	        hardware ethernet xx:xx:xx:xx:xx:xx;
		fixed-address 192.168.10.233;
		filename"/rootfs_r0p7785/uImage";
		option root-path "/tftpboot/rootfs_r0p7785";
	}

6.2  /etc/exports (Fedora 8 sample)

	/tftpboot/        192.168.10.0/255.255.255.0(rw,sync,no_root_squash)

6.3  /etc/xinetd.d/tftp (Fedora 8 sample)

	# default: off
	# description: The tftp server serves files using the trivial file transfer \
	#	protocol.  The tftp protocol is often used to boot diskless \
	#	workstations, download configuration files to network-aware printers, \
	#	and to start the installation process for some operating systems.
	service tftp
	{
		socket_type		= dgram
		protocol		= udp
		wait			= yes
		user			= root
		server			= /usr/sbin/in.tftpd
		server_args		= -s /tftpboot
		disable			= no
		per_source		= 11
		cps			= 100 2
		flags			= IPv4
	}

6.4  startup network (Fedora 8 sample)

  Then startup network servece on your host machine.

	[root@localhost ~]# exportfs -a
	[root@localhost ~]# /etc/rc.d/init.d/rpcbind restart
	Stopping portmap:                                          [  OK  ]
	Starting portmap:                                          [  OK  ]
	[root@localhost ~]# /etc/rc.d/init.d/nfs restart

	Shutting down NFS quotas:                                  [  OK  ]

	Starting NFS mountd:                                       [  OK  ]
	[root@localhost ~]# /etc/rc.d/init.d/nfslock restart
	Stopping NFS locking:                                      [  OK  ]
	Stopping NFS statd:                                        [  OK  ]
	Starting NFS statd:                                        [  OK  ]
	[root@localhost ~]# /etc/rc.d/init.d/dhcpd restart
	Shutting down dhcpd:                                       [  OK  ]
	Starting dhcpd:                                            [  OK  ]
	[root@localhost ~]# service xinetd restart
	Stopping xinetd:                                           [  OK  ]
	Starting xinetd:                                           [  OK  ]
