On some platforms, there is currently no way for the boot loader
|
||
|
|
to pass arguments to the kernel. For these, you should supply some
|
||
|
|
command-line options at build time by entering them here. At a
|
||
|
|
minimum, you should specify the memory size and the root device
|
||
|
|
(e.g., mem=64M root=/dev/nfs).

This allows you to specify the maximum number of CPUs which this

kernel will support. The maximum supported value is 6 and the

minimum value which makes sense is 2.

This is purely to save memory - each supported CPU adds

approximately eight kilobytes to the kernel image.
