47 The Extended Industry Standard Architecture (EISA) bus was
48 developed as an open alternative to the IBM MicroChannel bus.

50 The EISA bus provided some of the features of the IBM MicroChannel
51 bus while maintaining backward compatibility with cards made for
52 the older ISA bus. The EISA bus saw limited use between 1988 and
53 1995 when it was made obsolete by the PCI bus.
