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. |
