2424 | The Extended Industry Standard Architecture (EISA) bus was | |
2425 | developed as an open alternative to the IBM MicroChannel bus. | |
2426 | ||
2427 | The EISA bus provided some of the features of the IBM MicroChannel | |
2428 | bus while maintaining backward compatibility with cards made for | |
2429 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2430 | 1995 when it was made obsolete by the PCI bus. | |
2431 | ||
2432 | Say Y here if you are building a kernel for an EISA-based machine. | |
2433 | ||
2434 | Otherwise, say N. | |
