  1573. The Extended Industry Standard Architecture (EISA) bus was
  1574. developed as an open alternative to the IBM MicroChannel bus.
  1575. The EISA bus provided some of the features of the IBM MicroChannel
  1576. bus while maintaining backward compatibility with cards made for
  1577. the older ISA bus. The EISA bus saw limited use between 1988 and
  1578. 1995 when it was made obsolete by the PCI bus.
  1579. Say Y here if you are building a kernel for an EISA-based machine.

  1611. kernels that are loaded within the KSEG compatibility segments the

  1613. smaller binary, but this option is not explicitly supported by the
