1. Try the images/boot.iso or images/diskboot.img from CD or USB media
2. If you have some flavor of Linux installed, copy the isolinux/vmlinuz
and isolinux/initrd.img to /boot (renamed to *-c5* in GRUB example
below) and create a GRUB or LILO stanza to boot them.
title CentOS5 Installer
kernel /boot/vmlinuz-c5 ro ramdisk=8192
