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

143 | This allows you to specify the maximum number of CPUs which this |
144 | kernel will support. The maximum supported value is 6 and the |
145 | minimum value which makes sense is 2. |
146 | |
147 | This is purely to save memory - each supported CPU adds |
148 | approximately eight kilobytes to the kernel image. |
