5 | Find out whether you have a PCI motherboard. PCI is the name of a | ||
6 | bus system, i.e. the way the CPU talks to the other stuff inside | ||
7 | your box. If you have PCI, say Y, otherwise N. | ||

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