  1594. The Extended Industry Standard Architecture (EISA) bus was
  1595. developed as an open alternative to the IBM MicroChannel bus.
  1596. The EISA bus provided some of the features of the IBM MicroChannel
  1597. bus while maintaining backward compatibility with cards made for
  1598. the older ISA bus. The EISA bus saw limited use between 1988 and
  1599. 1995 when it was made obsolete by the PCI bus.
  1600. Say Y here if you are building a kernel for an EISA-based machine.
