1166 *not* work on R4000 machines and vice versa. However, since most
1167 of the supported machines have an R4000 (or similar) CPU, R4x00
1168 might be a safe bet. If the resulting kernel does not work,
1169 try to recompile with R3000.
1178 The options selects support for the NEC VR41xx series of processors.
