+          If you say N here, the kernel will run on single and multiprocessor

+          singleprocessor machines. On a singleprocessor machine, the kernel
+          will run faster if you say N here.
+
+          Note that if you say Y here and choose architecture "586" or
+          "Pentium" under "Processor family", the kernel will not work on 486
+          architectures. Similarly, multiprocessor kernels for the "PPro"
+          architecture may not work on all Pentium based boards.
+
+          People using multiprocessor machines who say Y here should also say
