13 The Extended Industry Standard Architecture (EISA) bus was
14 developed as an open alternative to the IBM MicroChannel bus.
16 The EISA bus provided some of the features of the IBM MicroChannel
17 bus while maintaining backward compatibility with cards made for
18 the older ISA bus. The EISA bus saw limited use between 1988 and
19 1995 when it was made obsolete by the PCI bus.
