97 | On some platforms, there is currently no way for the boot loader | |
98 | to pass arguments to the kernel. For these, you should supply some | |
99 | command-line options at build time by entering them here. At a | |
100 | minimum, you should specify the memory size and the root device | |
101 | (e.g., mem=64M root=/dev/nfs). | |

114 | This allows you to specify the maximum number of CPUs which this |

116 | minimum value which makes sense is 2. | |
