(However, I've never used Linux.) I use the make buildkernel make installkernel method. If your method has built a kernel in the same manner, though, you might be alright. When a new kernel is installed, the old one is renamed kernel.old. If this is the case, then you should still be able to boot from the previous kernel. When the loader prompt appears (press Enter to skip countdown, any other key to get the loader propmt... hit any key but Enter), type the following: boot /boot/kernel.old and if you do have the old kernel, it should boot, and everything should work as before. Then you should read the Handbook about building kernels in FreeBSD, and rebuild and install the GENERIC kernel. -- Bob
