Setting up a netboot environment

From within the ISO or image server root path, copy the netboot image (images/netboot/ppc64.img) to the TFTP server root directory (for example/tftpboot, see /etc/xinet.d/tftp) and make sure that it matches the respective entry in /etc/dhcpd.conf. For example:
host somehostname {
   allow bootp;
   allow booting;
   option host-name    "somehost.localdomain.com";
   hardware ethernet   00:20:9f:12:0f:19;
   fixed-address       10.3.5.11;
   filename            "ppc64.img";
   next-server         10.32.0.1;
}
