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