HELP: Kernel panic

Hello,

I have a problem after I upgrade the kernel. While I try to boot from the 
new updated kernel, I got an error -- "Kernel panic. No init found, try 
init = option to kernel"

What should I do now? I can still use old kernel, but I really need to use 
new kernel.

Some background: I installed the Redhat 7.2 through RAID card using Dell 
GX400 CPU, then I removed the harddrive to an Multi-CPU box. After moving, 
I found it still using the kernel for single CPU, therefore I have to 
change to use smp-kernel. I download one rpm from redhat website. After 
install, I got the above error. I have used the command lilo -v -v, but 
didn't help.


Following is my lilo.conf:
