| 632 | The Extended Industry Standard Architecture (EISA) bus was |
| 633 | developed as an open alternative to the IBM MicroChannel bus. |
| 634 | |
| 635 | The EISA bus provided some of the features of the IBM MicroChannel |
| 636 | bus while maintaining backward compatibility with cards made for |
| 637 | the older ISA bus. The EISA bus saw limited use between 1988 and |
| 638 | 1995 when it was made obsolete by the PCI bus. |
| 639 | |
| 640 | Say Y here if you are building a kernel for an EISA-based machine. |
