  7.4.  New version of the kernel doesn't seem to boot

  You did not run LILO, or it is not configured correctly. One thing
  that `got'' me once was a problem in the config file; it said `boot =
  /dev/hda1' instead of `boot = /dev/hda' (This can be really annoying
  at first, but once you have a working config file, you shouldn't
  to change it.).
