1249 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1250 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1251 | *not* work on R4000 machines and vice versa. However, since most | |

1253 | might be a safe bet. If the resulting kernel does not work, | |
1254 | try to recompile with R3000. | |
