+      you can go about this. First, see if your Linux vendor provides a &min-kernel;
+      or later kernel package. If so, you may wish to install it. If your
+      vendor doesn't offer an acceptable kernel package, or you would prefer not to
+      install it, you can compile a kernel yourself. Instructions for
+      compiling the kernel and configuring the boot loader (assuming the host
