2102 | The Extended Industry Standard Architecture (EISA) bus was | |
2103 | developed as an open alternative to the IBM MicroChannel bus. | |
2104 | ||
2105 | The EISA bus provided some of the features of the IBM MicroChannel | |
2106 | bus while maintaining backward compatibility with cards made for | |
2107 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
2108 | 1995 when it was made obsolete by the PCI bus. | |
