| 1184 | Please make sure to pick the right CPU type. Linux/MIPS is not |
| 1185 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will |
| 1186 | *not* work on R4000 machines and vice versa. However, since most |
| 1187 | of the supported machines have an R4000 (or similar) CPU, R4x00 |
| 1188 | might be a safe bet. If the resulting kernel does not work, |
| 1189 | try to recompile with R3000. |
