81 If you have one of the following DECstation Models you definitely
82 want to choose R4xx0 for the CPU Type:
83
84 DECstation 5000/50
85 DECstation 5000/150
86 DECstation 5000/260
87 DECsystem 5900/260

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

1903 64-bit binaries using 32-bit quantities for addressing and certain
1904 data that would normally be 64-bit. They are used in special
1905 cases.
