Updating the custom kernel AFTER DSL HD install

Can't seem to find another appropriate place or this question so I appologize if it is the wrong forum.

After I do DSL HD install, it boots up GREAT! No issue there. But I want to update to a custom 2.6 kernel...

So I install a second HD, boot Knoppix and compile a new kernel modules etc. Now I have "bzImage2.6" and "" modules..

I copied the files over to the HD where the DSL installation is (hda1) and modify /dev/hda1 -> /etc/lilo.conf to point to bzImage2.6 and rerun lilo.

It hangs after lilo.

What did I do wrong and can someone point me to some doc of how to update the kernel for DSL after HD-DSL installation..

Thanks in advance,
