150 If you have one of the following DECstation Models you definitely
151 want to choose R4xx0 for the CPU Type:
152
153 DECstation 5000/50
154 DECstation 5000/150
155 DECstation 5000/260

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
