Matthew:  You're welcome. As Kai wrote earlier, you need to change the
line that says default=n to the "title" line for the kernel you want
to use (I think it defaults to 0, after a Kernel upgrade). Every time
you install a new kernel, it will change this file, so you may need to
go back and tweak it, after a kernel upgrade. Lanny
