I am a total

running Win Linux 2003, which uses 2.4.18. I tried to update to 2.4.27, and everything seemed to install ok, I was able to add the new kernel to lilo.
But what happens is that when I try to boot to the new kernel, the system immediately just restarts. If I select the old kernel in lilo, it boots ok. I must have overlooked something obvious, but what?
