1379 Please make sure to pick the right CPU type. Linux/MIPS is not
1380 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1381 *not* work on R4000 machines and vice versa. However, since most
1382 of the supported machines have an R4000 (or similar) CPU, R4x00
1383 might be a safe bet. If the resulting kernel does not work,
1384 try to recompile with R3000.
