1029 Please make sure to pick the right CPU type. Linux/MIPS is not
1030 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1031 *not* work on R4000 machines and vice versa. However, since most
1032 of the supported machines have an R4000 (or similar) CPU, R4x00
1033 might be a safe bet. If the resulting kernel does not work,
1034 try to recompile with R3000.

1978 Select this option if you want Linux/MIPS 32-bit binary
1979 compatibility. Since all software available for Linux/MIPS is
1980 currently 32-bit you should say Y here.

1996 Select this option if you want to run o32 binaries. These are pure
1997 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
