1672 | you have a system with more than one CPU, say Y. | |

1675 | machines, but will use only one CPU of a multiprocessor machine. If | |
1676 | you say Y here, the kernel will run on many, but not all, | |
1677 | singleprocessor machines. On a singleprocessor machine, the kernel | |
1678 | will run faster if you say N here. | |

1680 | People using multiprocessor machines who say Y here should also say | |
1681 | Y to "Enhanced Real Time Clock Support", below. | |
