 233           Find out whether you have a PCI motherboard. PCI is the name of a
 234           bus system, i.e. the way the CPU talks to the other stuff inside
 235           your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
 236           VESA. If you have PCI, say Y, otherwise N.
 237
 238           The PCI-HOWTO, available from
 239           <http://www.tldp.org/docs.html#howto>, contains valuable
 240           information about which PCI hardware does work under Linux and which

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