You need to modify MILO 0.27.1 to properly detect the RM200 ISA.
The ARC firmware in the RM200 loads the kernel with a 8 byte offset to
what is expected (bug, bug ;-)), so the ARC bootloader jump to the wrong 
address. Btw., you should specify the "-v" flag to milo to get some nice
output about what the ARC console thinks the system is :).

I put the modified milo 0.27.1 and pandora on  
ftp://ftp.unix-ag.org/pub/os/linux/mips/rm200/
- just give it a try !

I can build a kernel for the RM200 ISA later, it's currently in a big tar.gz
file as I ran out of disk space ...

regards,
        Michael
