IRIX 6.3

Post by JacquesT » Thu Jun 28, 2018 4:12 pm

Does anybody have Irix 6.3 running on an O2? Is it usable for apps like Maya 4 / 5, Softimage, Lightwave and Photoshop?

I don't believe nekoware works on 6.3?

What about mplayer etc? Or is it best to stick with 6.5.22 / .30?

I ran IRIX 6.3 on my O2 for a little while, but it got much better going to 6.5.22m. Max MIPSPro compiler version was 7.3 and you had to patch that. No nekoware as well. Also, no R12K or RM5200 or QED7K processor support.

Also, an O2 with 6.3 came shipped with an awful IBM SCA drive as root device which were really slow and noisy. Better get some sweet 36GB Maxtors or seagates. Only drawback is that 6.5.x eats more memory, so investment in extra ram doesn't hurt.

Thank you very much, that answers that as I have a RM5200 300Mhz pimm. I'll stick with 6.5.22m then.

I have 384Mb ram, I would love to get to 512mb/758mb but that will have to wait.

384MB is fine for running regular 6.5.22m plus a cool program. My R5k only has 128MB and that hurts a bit.

I second that. I have an o2 with 384MB and 6.5.22m and everything I tried runs just fine with no swapping. Effect/Maya/Alias no issues

My O2 is happily running with .22m now, I'm slowly setting up the machine, next thing to do after that is to bring the 1600SW to connect to the O2.

I've got a 250Mhz R10K module on the way as a backup fo a possible future upgrade. I thought I had a spare R10k chassis but it's an old R5k one. May have to drill, but I'd prefer to just nab a really cheap R10k chassis somewhere.

so wait - you have a R5k O2 right? It might not be so easy to just flop a R10k CPU in there (I thought about trying a mod where I stick a R10k CPU into a R5k O2, but I don't think its trivial at all).

At the very worst case, you can convert many r5k chassis into R10k chassis by checking the bottom of the o2 - if you see two screws on the bottom, you can unscrew them and remove the drive bay separator next to the system board:

r5k chassis:

same chassis with plate removed == now a r10k chassis:
o2-r10k.jpg
But this is the easy part - the hard part is getting a system board shell (the system board itself is the same), and even harder to get are the little extender pins and plastic mount needed to actually plug in the R10k module.

so unless you can get the plastic mount for a r10k cpu and the 2 extenders, your screwed. Best bet is to buy a fully working R10k o2, 2nd best option is to buy a R10k systemboard that still has a cpu attached and if you have the model chassis that can be both R5k and R10k, worst bet is try to locate the needed pieces yourself.

Maybe even worse is trying to mod the r5k o2 with a R10k module - I am pretty sure its doable but def gonna risk killing your board (main thing that stopped me was it looked like I might have had to shave down a heatsink on something that was in the way of mounting the R10k cpu using the R5k mounting hardware, and the one person that said on nekochan they did it said they basically lost the ability to use the PCI slot, which is important to me for a 3rd scsi channel

I know :( my shopping list includes the mainboard plastic shell, metal case and extender pins. I thought about mounting the R10k on the R5k pins but one of the heatsinks on the system board is too tall. You can just about fit the shorter PCI riser card on with a R10k cpu module.

It's a nice to have, but not essential. Full O2 machines are just too expensive to warrant the cost just to go to R10k/R12k cpu when I have an R12k Octane.

yeah that's the one. I was going to shave it down and see what happens...

Come to think of it I just happen to have a dead o2 main board and a few spare r10k cpu's... so maybe I might give it a test run just to see what's really needed...

yeah, your right - I guess I was never happy with my o2 until I maxed it out. all my other SGI's are much faster but I find myself using the o2 more just because its small, quite and real quick to just turn on and off - with all the stuff going on in my life I can maybe get an hour in every other day with the sgi stuff. When I need to do some serious lifting I power up my tezro (for example stuff that takes an hour to compile on my o2 takes 5 min on the tezro). on a side note - I do have an onyx350 sitting here too, but I need to get more power in my room before I can turn it on...

I've set up my 1600sw so it's quite nice to use this with the O2. The 1600sw has some fading backlights as it's quite old but still quite nice if you calibrate it with colorlock.

I have two O2 motherboards, one has a short stubby heatsink on that chip and the other a taller one. The shorter (it's stock, no mods) one gets VERY hot and together with the ram, generates all the heat in the machine. The cpu is quite cool after 15 mins use.
