help
|

This enables support for systems with more than one CPU. If
|
|
you say N here, the kernel will run on single and
|
|
multiprocessor machines, but will use only one CPU of a
|
|
multiprocessor machine. If you say Y here, the kernel will run
|
|
on many, but not all, single processor machines. On a single
|
|
processor machine, the kernel will run faster if you say N
|
|
here.
|
|
|
|
If you don't know what to do here, say N.
