780 | Some MIPS machines can be configured for either little or big endian | |
5e83d430 | 781 | byte order. These modes require different kernels and a different |
3cb2fccc | 782 | Linux distribution. In general there is one preferred byteorder for a |
5e83d430 | 783 | particular system but some systems are just as commonly used in the |
3dde6ad8 | 784 | one or the other endianness. |

1647 | kernel and 64 for 64-bit kernels; the minimum value which makes | |
