94 | you can go about this. First, see if your Linux vendor provides a &min-kernel;
|

95 | or later kernel package. If so, you may wish to install it. If your

96 | vendor doesn't offer an acceptable kernel package, or you would prefer not to

97 | install it, you can compile a kernel yourself. Instructions for

99 | uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>
