-> Hi all,
-> I just got an Origin200 from a friend free. I'm fairly familiar with 
-> the lower end SGI models, but not so much with these. I want to try 
-> and take a stab at getting NetBSD to support this monster. So I have 
-> a couple of quick questions:
-> 
-> 1. Is there a way ARCS(which is a completely different version than 
-> previous ARCS?) can load 32bit ELF kernels?

Probably not ELF32 kernels; IIRC, the trick the Linux-MIPS people use is
to link it as a 32-bit kernel then convert to ELF64 via an objcopy which
changes addresses (via --change-addresses) by adding in the "upper half"
of the address.

-> 2. Could there be a secondary boot-loader that's 64bits that just 
-> loads the 32bit kernel? What are the basic implications?

I think as Soren points out, this is probably doable; I don't think this
is like the R8k where you don't have a 32-bit mode at all 8-)

-> I haven't had a chance to look at the Linux code base yet (they seem 
-> to have initial support for the O200, yet the oss.sgi.com cvs server 
-> seems to be down) so I thought I'd ask here first. Sorry for my naive 
-> questions, I'm fairly new to MIPS et al. Thanks in advance!

OSS got moved somewhere... Lemme dig out the addresses from my archive..
