Yeah, I know. Not the same. And there's no documentation of this dualie carrier sadly.

That guy in Florida who had a whole bunch of oddball stuff wrote up his method with photos, maybe saved soemwhere ?

It wasn't very difficult, anyhow. The biggest problem is the middle latch. I think he just skipped using it, maybe.

Richtom ?

DCDs are a grand now ? that's ridiculous. A second V12 would do a better job.  The nicest thing about the dcd is the dvi connectors.

As someone who is running more or less this exact configuration (to support the Octane Digital Video option), I can attest that it's flaky. The PROM will only display on the ESI, certain full-screen demos won't run, and you do only get GL support on one screen as Raion said. You can link the screens into one large desktop, but there will be no GL support at all. Definitely not worth the trouble in my mind.

I've had an idea for a while to try using a CADDuo (which I have, and which are relatively inexpensive on eBay when they show up) to see how well that isolates each card, but I don't have a PCI card cage for my Octane yet. I'll certainly report on how things go when that changes, though!

That's interesting, I wonder why the Octane integration is so flaky, while the Tezros' has always been flawless (in my experience)? I got one from Raion several months ago (and for considerably less than a grand, thanks R!), and I haven't had a single problem with it. Are they the same board?

The graphics boards are not the same.

I thought the cad dual required 2 keyboards as it was meant to have 2 users share 1 octane, hence the dual display and dual keyboard, mouse inputs.

Yep, it does. I'm curious to see how the Octane/IRIX handles the different video adapters, GL, and the output from the Digital Video Option. It may well break in crazy ways. We'll see!

Hi Kaigan,

can you elaborate a bit more on any special configuration you had to do with IRIX to get V12 (Odyssey) and SI (Impact) graphics to work on same machine.

I was thinking of doing some tinkering with IR (Kona) graphics and V12 (Odyssey) and was wanting to avoid having to physically remove the V12 card from O350 chassis.

Was hoping I could just do some type of SW switching.

Cheers from Oz,

It wasn't very difficult. Again, this was specifically on an Octane(2). The V12 was in slot A and the ESI was in slot C. I installed IRIX fresh from Booterizer, and the standard commands provided appropriate drivers for both the Odyssey and Impact graphics. IRIX seems to somewhat randomly prefer to accelerate one card over the other between the installations I've tried and I'm not certain how to switch which card received the GL acceleration.

First of all, if you mean that you have the massive 12U rackmount unit that provides support for IR graphics on the O350, I'm *extremely* jealous. I'd love to have one.

I can't say with any certainty that such a config will work on an O350. The Onyx350/Onyx4 manuals state that it's one or the other. I don't imagine that connecting both would break anything, but it may operate very strangely, if at all. Still, it's worth the try in my mind. I'll poke around through documentation and see if I can find further information on how IRIX could be configured to switch which card is being accelerated. Given that it's a completely unsupported config, there may not be a good option for it. Hopefully I can find something.

Hi Kaigan,

I did read docs, about not being able to have both IR (yes the big beast) or V12, which is why I was curious about your Octane setup.

I did once have an MXE with Personal Video EVO board (now long gone on ebay) in my Octane2 and as I recall I was able to swap this and V12, as I had SW installed for both, but in my case I only had single set of HW installed at any given time.

This is long term project as IR is currently with another Aussie sgi "maniac" :-) , and needs to be couriered from interstate.

Your setup gives me reason to hope that I might be able to do this and get it to work by just unplugging IR when I want to just use simpler and less noicey V12 setup.

I will give it a go around mid March and see if it is possible to have "power" of IR with general convenience of V12 most of the time.

Thanks for providing info.

Cheers from Oz,

Hi kaigan,

I finally got to testing this with V12 and IR in same machine.


What I found was:

1. O350 with V12 in chassis + IR connected via XIO Link and booted from IRIX with IR Graphics , it just ignores that V12 (it does not even show up in HINV) and  runs machine as if it is IR graphics only

2. O350 with V12 in chassis + IR connected via XIO (but not powered up) and booted from IRIX with Odyssey/VPro Graphics, boot and runs as InfinitePerformance (V12) machine

3. O350 with V12 in chassis + IR connected via XIO (powered up) and booted from IRIX with Odyssey/VPro Graphicss, boot fails part way through with "HARDWARE ERROR" message on console.


So the answer is that you can have V12 (InfinitePerformance) and InfiniteReality on the same machine, but you have to have two distinct boot disks.

This is pretty good, as I do not have to remove the V12 to run the IR graphics. As swapping out boot disk is way easier then pulling a V12 board out of an O350 chassis.

For the moment I am running machine as IR, but that is due to it being the shiny new toy at the moment as I learn about how to get this configuration up and running smoothly.
