help

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

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