151 want to choose R4xx0 for the CPU Type:
152
153 DECstation 5000/50

541 can simulate a MIPS32 4Kc system. This patch adds support for the
542 system architecture that currently is being simulated by Qemu. It
543 will eventually be removed again when Qemu has the capability to
544 simulate actual MIPS hardware platforms. More information on Qemu
