<note><para>By default, Grub will automatically pass a "mem=xxx" command line
argument to the kernel. However, Grub sometimes gets the amount of memory wrong
which can lead to problems in some circumstances. It's best to disable this
functionality and let the kernel determine the amount of memory itself, hence
the use of the <emphasis>--no-mem-option</emphasis> above.</para></note>
