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). | |

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