| * Vector table at the beginning of the image for starting system. The reset |
| * vector is the system entry point, ie. the first instruction executed. |
| * |
| * The table is populated with all the system exception handlers. The NMI vector |
| * must be populated with a valid handler since it can happen at any time. The |
| * rest should not be triggered until the kernel is ready to handle them. |
