If that's what happened you either need to reinstall FreeBSD or boot the install/rescue cd and try to copy the generic kernel from it. That handbook page has a lot of good information, but most of it is preventative. The best suggestion is to always keep a working copy of the kernel seperate from the kernel.old that FreeBSD makes for you. HTH Micah
