  1559. Find out whether you have a PCI motherboard. PCI is the name of a
  1560. bus system, i.e. the way the CPU talks to the other stuff inside
  1561. your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
  1562. say Y, otherwise N.
  1563. The PCI-HOWTO, available from
  1564. <http://www.tldp.org/docs.html#howto>, contains valuable
  1565. information about which PCI hardware does work under Linux and which
  1566. doesn't.

  1583. The Extended Industry Standard Architecture (EISA) bus was
  1584. developed as an open alternative to the IBM MicroChannel bus.
  1585. The EISA bus provided some of the features of the IBM MicroChannel
  1586. bus while maintaining backward compatibility with cards made for
  1587. the older ISA bus. The EISA bus saw limited use between 1988 and
  1588. 1995 when it was made obsolete by the PCI bus.
  1589. Say Y here if you are building a kernel for an EISA-based machine.
  1590. Otherwise, say N.
