2024 | The EISA bus provided some of the features of the IBM MicroChannel | |
2025 | bus while maintaining backward compatibility with cards made for | |
2026 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2027 | 1995 when it was made obsolete by the PCI bus. | |
2028 | ||
2029 | Say Y here if you are building a kernel for an EISA-based machine. | |

2031 | Otherwise, say N. | |
