Ahh, OK. So the PROM is smart enough to use the first CDROM available.

Good to know. I have no closer experience with IRIX prior to 6.5.

He. I have all my machines in an extra room and use long extension
cables for K/V/M to get the console into the living room. So I don't
care about noise. :-)

It will be interresting to hear how much noise the O2 and the Origin 200
generate that I will get next weekend. I suspect that the O2 is not that
loud, but the Origin 200...

Sure. You have to be lucky and you can't expect more then SI / ESI GFX.
But R10k / SI Octanes are really down below 100,- EUR.

Firefox / Mozilla...
Cross building NetBSD.
Viewing bloated PDFs.

I also used a 150 MHz (later 200 MHz) Indigo2 Extreme and there is still
a R4k4 Indy on my desk... I played a bit with IRIX 3.3 on a PI4D35...
Not to speak about all that non-SGI stuff, including VAXen that are much
slower then a 40 MHz R3k...
