Chapter 8. Operating system installation 363
4. The netboot image is larger than 65,500 512 bytes blocks and cannot be
used due to a limitation of tftpd. We must boot the vmlinuz kernel and use
the ramdisk image. Copy the two files from the ppc/ppc64 directory of the
DVD to the tftpboot directory of the installation server.
5. On the installation server, create a directory named tftpboot/etc, and create
a file named 00-XX-XX-XX-XX-XX-XX, replacing all characters except the 00
with the target virtual server MAC address, as shown in Figure 8-48.
Figure 8-48 00-XX-XX-XX-XX-XX-XX file
6. The dhcpd.conf file is displayed in Figure 8-49. It is similar to the SLES
version. Again, change the network addresses and the MAC address and the
IP configuration to your environment settings.

Tip: The yaboot executable is named simply yaboot. We can rename it, for
example, to yaboot.rh61, to avoid conflicts in the tftpboot directory.
