| 144 | On some platforms, there is currently no way for the boot loader |
| 145 | to pass arguments to the kernel. For these, you should supply some |
| 146 | command-line options at build time by entering them here. At a |
| 147 | minimum, you should specify the memory size and the root device |
| 148 | (e.g., mem=64M root=/dev/nfs). |

| 170 | |
