1921 This enables support for systems with more than one CPU. If you have
1922 a system with only one CPU, like most personal computers, say N. If
1923 you have a system with more than one CPU, say Y.
1924
1925 If you say N here, the kernel will run on single and multiprocessor
1926 machines, but will use only one CPU of a multiprocessor machine. If
1927 you say Y here, the kernel will run on many, but not all,
1928 singleprocessor machines. On a singleprocessor machine, the kernel
1929 will run faster if you say N here.

1932 Y to "Enhanced Real Time Clock Support", below.
