1658 | bus system, i.e. the way the CPU talks to the other stuff inside | |

1686 | The Extended Industry Standard Architecture (EISA) bus was | |
1687 | developed as an open alternative to the IBM MicroChannel bus. | |
1688 | ||
1689 | The EISA bus provided some of the features of the IBM MicroChannel | |
1690 | bus while maintaining backward compatibility with cards made for | |
1691 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
1692 | 1995 when it was made obsolete by the PCI bus. | |
1693 | ||
1694 | Say Y here if you are building a kernel for an EISA-based machine. | |

1734 | A 64-bit kernel is usually built using the 64-bit ELF binary object | |

1736 | kernels that are loaded within the KSEG compatibility segments the | |
1737 | 32-bit ELF format can optionally be used resulting in a somewhat | |
1738 | smaller binary, but this option is not explicitly supported by the | |

1792 | This kernel feature is useful for number crunching applications | |
