          Find out whether you have a PCI motherboard. PCI is the name of a
          bus system, i.e. the way the CPU talks to the other stuff inside
          your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
          VESA. If you have PCI, say Y, otherwise N.

          The PCI-HOWTO, available from
          <http://www.tldp.org/docs.html#howto>, contains valuable
          information about which PCI hardware does work under Linux and which
          doesn't.

          Enable this option if your platform does not have a CPU cache which
          remains coherent with PCI DMA. It is safest to say 'Y', although you
          will see better performance if you can say 'N', because the PCI DMA
          code will not have to flush the CPU's caches. If you have a PCI host
          bridge integrated with your SH CPU, refer carefully to the chip specs
          to see if you can say 'N' here. Otherwise, leave it as 'Y'.
