109 string "Default kernel command string"
112 On some platforms, there is currently no way for the boot loader
113 to pass arguments to the kernel. For these, you should supply some
114 command-line options at build time by entering them here. At a
115 minimum, you should specify the memory size and the root device
116 (e.g., mem=64M root=/dev/nfs).
119 bool "Multi-Processing support"
121 Enables SMP support in the kernel. If unsure, say "Y"
124 int "Maximum number of CPUs" if SMP
129 This allows you to specify the maximum number of CPUs which this
130 kernel will support. The maximum supported value is 6 and the
131 minimum value which makes sense is 2.
133 This is purely to save memory - each supported CPU adds
134 approximately eight kilobytes to the kernel image.
