1186 Please make sure to pick the right CPU type. Linux/MIPS is not
1187 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1188 *not* work on R4000 machines and vice versa. However, since most
1189 of the supported machines have an R4000 (or similar) CPU, R4x00
1190 might be a safe bet. If the resulting kernel does not work,
1191 try to recompile with R3000.

1893 This enables support for systems with more than one CPU. If you have
1894 a system with only one CPU, like most personal computers, say N. If
1895 you have a system with more than one CPU, say Y.
1896
1897 If you say N here, the kernel will run on single and multiprocessor
1898 machines, but will use only one CPU of a multiprocessor machine. If
1899 you say Y here, the kernel will run on many, but not all,
1900 singleprocessor machines. On a singleprocessor machine, the kernel
1901 will run faster if you say N here.
1902
1903 People using multiprocessor machines who say Y here should also say
1904 Y to "Enhanced Real Time Clock Support", below.
