1679 | The Extended Industry Standard Architecture (EISA) bus was | |
1680 | developed as an open alternative to the IBM MicroChannel bus. | |
1681 | ||
1682 | The EISA bus provided some of the features of the IBM MicroChannel | |
1683 | bus while maintaining backward compatibility with cards made for | |
1684 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
1685 | 1995 when it was made obsolete by the PCI bus. | |
1686 | ||
1687 | Say Y here if you are building a kernel for an EISA-based machine. | |

1727 | A 64-bit kernel is usually built using the 64-bit ELF binary object | |

1729 | kernels that are loaded within the KSEG compatibility segments the | |

1731 | smaller binary, but this option is not explicitly supported by the | |

1785 | This kernel feature is useful for number crunching applications | |
