Not good :-(

It's definetly a hardware fault or prom bug. The only thing you can do it
to try removing some memory, clean all the connectors you can on the
system, reseat the cpu module.

Otherwise it's a new motherboard :-( But your in luck as you have an
R5000 system you can replace the mother board for £50 or so and you'll
probably get a faster system .

Hello,

thanks for your reply

I'm making some progress now. I'm using a nullmodemcable to get the
console output to minicom on my Linux system. And guess what - the
system boots!
My guess is that there is some hardware error on the onboard GFX. Is
it possible to use a PC-type PCI graphics adapter to the system?

Please note that I'm very new to SGI machines

Thanks
Robert

As a general rule, no. The O2 uses an internal graphics system (CRM)
which is colloquially referred to as "Crime" graphics. Crime is cool
because it uses your internal memory as texture RAM; the more RAM you
have, the more textures you can have immediately available to the
graphics system.

I think Crime also ties into the video module in a very special way, so
even if you could use a standard PC video card I suspect it'd prevent
your captures from working. It'd certainly prevent you from using a
live video stream as a texture in OpenGL.

best always,
