2074 | The EISA bus provided some of the features of the IBM MicroChannel | |
2075 | bus while maintaining backward compatibility with cards made for | |
2076 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2077 | 1995 when it was made obsolete by the PCI bus. | |
2078 | ||
2079 | Say Y here if you are building a kernel for an EISA-based machine. | |

2081 | Otherwise, say N. | |
