 227           Find out whether you have a PCI motherboard. PCI is the name of a
 228           bus system, i.e. the way the CPU talks to the other stuff inside
 229           your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
 230           VESA. If you have PCI, say Y, otherwise N.
 231
 232           The PCI-HOWTO, available from
 233           <http://www.tldp.org/docs.html#howto>, contains valuable
 234           information about which PCI hardware does work under Linux and which

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