3117 The Extended Industry Standard Architecture (EISA) bus was
3118 developed as an open alternative to the IBM MicroChannel bus.
3119
3120 The EISA bus provided some of the features of the IBM MicroChannel
3121 bus while maintaining backward compatibility with cards made for
3122 the older ISA bus. The EISA bus saw limited use between 1988 and
3123 1995 when it was made obsolete by the PCI bus.
3124
3125 Say Y here if you are building a kernel for an EISA-based machine.
3126
3127 Otherwise, say N.
