| 11 | The nodes of Origin 200, Origin 2000 and Onyx 2 systems can be |
| 12 | configured in either N-Modes which allows for more nodes or M-Mode |
| 13 | which allows for more memory. Your system is most probably |
| 14 | running in M-Mode, so you should say N here. |

| 20 | Change the way a Linux kernel is loaded into memory on a MIPS64 |
| 21 | machine. This is required in order to support text replication and |
| 22 | NUMA. If you need to understand it, read the source code. |
