1146 Please make sure to pick the right CPU type. Linux/MIPS is not
1147 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1148 *not* work on R4000 machines and vice versa. However, since most
1149 of the supported machines have an R4000 (or similar) CPU, R4x00
1150 might be a safe bet. If the resulting kernel does not work,
1151 try to recompile with R3000.
1160 The options selects support for the NEC VR41xx series of processors.
1161 Only choose this option if you have one of these processors as a
