Hi, I have CentOS 4.4 with me. I want to change the default kernel during installation, from 2.6.9 to 2.6.15. I got myself a copy of vmlinuz and initrd.img from the RHEL AS 4.0 installation cd and copied it as vmlinuz-rhel and initrd-rhel.img respectively into the isolinux folder on the CentOS cd. I changed isolinux.cfg so that it would boot into my kernel. I then made a fresh new ISO and tried to boot off it. However, when I boot I get the following error "Cannot find kernel image: vmlinuz-rhel". I cant figure out where the boot loader is looking for vmlinuz and initrd (besides the islinux directory) and if there are any other norms that Im not sticking too.
Thanks, Janice.

Doing this is very much not advised, as the kernel is very closely tied to the rest of the distro. However, were you to insist on doing so, you're going to have to wrestle with anaconda in getting this kernel to work. The build scripts for iso generation are posted on the mirrors, and should be a reasonable reference for you. Without a sane reason for doing this, I really don't want to help you any further, as you're moving away from the supported release.
