1165 | Please make sure to pick the right CPU type. Linux/MIPS is not | |
1166 | designed to be generic, i.e. Kernels compiled for R3000 CPUs will | |
1167 | *not* work on R4000 machines and vice versa. However, since most | |
1168 | of the supported machines have an R4000 (or similar) CPU, R4x00 | |
1169 | might be a safe bet. If the resulting kernel does not work, | |
1170 | try to recompile with R3000. | |

2030 | A 64-bit kernel is usually built using the 64-bit ELF binary object | |
2031 | format as it's one that allows arbitrary 64-bit constructs. For | |
2032 | kernels that are loaded within the KSEG compatibility segments the | |
2033 | 32-bit ELF format can optionally be used resulting in a somewhat | |
2034 | smaller binary, but this option is not explicitly supported by the | |
2035 | toolchain and since binutils 2.14 it does not even work at all. | |
2036 | ||
2037 | Say Y to use the 64-bit format or N to use the 32-bit one. | |
2038 | ||
2039 | If unsure say Y. | |
