1561 | *not* work on R4000 machines and vice versa. However, since most | |

3121 | The Extended Industry Standard Architecture (EISA) bus was | |
3122 | developed as an open alternative to the IBM MicroChannel bus. | |
3123 | ||
3124 | The EISA bus provided some of the features of the IBM MicroChannel | |
3125 | bus while maintaining backward compatibility with cards made for | |
3126 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
3127 | 1995 when it was made obsolete by the PCI bus. | |
3128 | ||
3129 | Say Y here if you are building a kernel for an EISA-based machine. | |
3130 | ||
3131 | Otherwise, say N. | |
