1545 | MIPS64 architecture. New MIPS processors, starting with the Warrior | |

1556 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1557 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1558 | *not* work on R4000 machines and vice versa. However, since most | |
1559 | of the supported machines have an R4000 (or similar) CPU, R4x00 | |
1560 | might be a safe bet. If the resulting kernel does not work, | |
1561 | try to recompile with R3000. | |

2882 | running a MIPS32 system and know that none of your userland binaries | |
