1032 Please make sure to pick the right CPU type. Linux/MIPS is not
1033 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1034 *not* work on R4000 machines and vice versa. However, since most
1035 of the supported machines have an R4000 (or similar) CPU, R4x00
1036 might be a safe bet. If the resulting kernel does not work,
1037 try to recompile with R3000.
