 240           Find out whether you have a PCI motherboard. PCI is the name of a
 241           bus system, i.e. the way the CPU talks to the other stuff inside
 242           your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
 243           VESA. If you have PCI, say Y, otherwise N.
 244
 245           The PCI-HOWTO, available from
 246           <http://www.tldp.org/docs.html#howto>, contains valuable
 247           information about which PCI hardware does work under Linux and which
 248           doesn't.

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