1033 Please make sure to pick the right CPU type. Linux/MIPS is not
1034 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1035 *not* work on R4000 machines and vice versa. However, since most
1036 of the supported machines have an R4000 (or similar) CPU, R4x00
1037 might be a safe bet. If the resulting kernel does not work,
1038 try to recompile with R3000.

1975 Select this option if you want Linux/MIPS 32-bit binary
1976 compatibility. Since all software available for Linux/MIPS is
1977 currently 32-bit you should say Y here.

1992 help
1993 Select this option if you want to run o32 binaries. These are pure
1994 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1995 existing binaries are in this format.

1997 If unsure, say Y.

2002 help
2003 Select this option if you want to run n32 binaries. These are
2004 64-bit binaries using 32-bit quantities for addressing and certain
2005 data that would normally be 64-bit. They are used in special
2006 cases.
