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

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

1390 if the target TC is interrupt-inhibited (IXMT). In the first

1893 Select this option if you want to run o32 binaries. These are pure
1894 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1895 existing binaries are in this format.
