want to choose R4xx0 for the CPU Type:
DECstation 5000/50
DECstation 5000/150
DECstation 5000/260

Some MIPS machines can be configured for either little or big endian
byte order. These modes require different kernels and a different
Linux distribution. In general there is one prefered byteorder for a
particular system but some systems are just as commonly used in the
one or the other endianess.
