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
241 doesn't.

246 default y
247 help
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'.
