  1570. The Extended Industry Standard Architecture (EISA) bus was
  1571. developed as an open alternative to the IBM MicroChannel bus.
  1572. The EISA bus provided some of the features of the IBM MicroChannel
  1573. bus while maintaining backward compatibility with cards made for
  1574. the older ISA bus. The EISA bus saw limited use between 1988 and
  1575. 1995 when it was made obsolete by the PCI bus.
  1576. Say Y here if you are building a kernel for an EISA-based machine.
  1577. Otherwise, say N.
