Re: Internals of the duel R14k CPU modules, upgrading modules by replacing CPUs

The other issue is that documentation for the silicon starts drying up at about the R12k. You can find lots on the R10k and earlier, but after 12k it was pretty much SGI-only. I don't have much that new, but on the earlier chips multiplier was set on startup from a serial EPROM, along with cache siz...

Re: Rack mounting SGI Origin

No rails. There are brackets that bolt it in to the rack and heavy angle support brackets to take the weight on the bottom. Officially it has the plenum to direct the air to the front/back, but I pulled mine on my O2k so I can drop the lower module and put some more equipment in the rack. It blows d...

Re: Indigo 4000 power on till chime and dead

If I understand properly the PSU is shutting down, correct? If so then that means that something is either going wrong in the PSU (voltages off), there's something drawing too much power in the computer and tripping the protect circuit, or the PSU can't put out the needed power. What exactly was &qu...

Re: SGI PROM binaries? ... Solved

Solid IMPACT was introduced slightly after High/Max IMPACT, so there's a possibility that v11 was made before Solid was a product. There's a big difference between Solid and High/Max with the absence of texturing, whereas with most SGI graphics the difference is in number of processors or amount of ...

Re: SGI 2200

I have one that had several optical FC adapters in shoehorns. What I wound up doing was just keeping the adapters in but pulling them out a bit so they correctly direct the airflow but don't take any power. You can use two of your shoehorns (XIO to PCI adapters) to install GigE cards and have the O2...

Re: SGI 2200

Just a clarification: On an Onyx2 deskside two of the nodeboard slots are taken up by graphics. SGI still needed a bit more space for the graphics to fit. Because there are only two nodeboards they were able to get away with a null router installed in a single router slot, and the second router slot...

Re: OpenVMS Hobbyist Kit

Not only have things changed often, the changes haven't always been announced quickly or in a widespread way. I remember taking a few weeks to figure out how to get updated PAKs when HP took it in-house. I'm wondering what the future holds. I can't imagine HPE is jumping with joy at the program give...

Re: Irix 5.3 Variants

A while back I was working on a "5.3 with XFS for everything" that included a rebuilt miniroot that supported 2MB SC. I got that part working before life intervened, but there was some funkiness in the later install packages that wouldn't work right. I suppose I could get back to it and se...

No. I don't have the tools to pull the CPUs to get the mainboard out. I also have a dual G4 that I was given at about the same time that will work for what I'd be using a PPC mac for.

Re: Openwin 3.0 problems setting resolution on SUN IPX

Do you have a CG6 SBus card to try?

What are the sense pins wired up for in the adapter? There's a list of resolutions at http://ps-2.kev009.com/rs6000/13w3/13w3_pinout.html.

free not-working Mac G5 DP 1.8

Pretty much just as it sounds. Lights come on but no boot. I don't have the tools to re-seat the CPU, so it could be that but it could also be the memory controller. Not something that will have everyone drooling, but I thought I'd offer it before scrapping. Case is in decent shape, possibly a coupl...

Re: What mips flavor is the 6.5.22m /unix kernel on R5K Indy's?

I think SGI tended to build things lower down unless there was a significant performance gain. I remember being surprised that IRIX 6.2 came back as MIPS-2 (can't remember if this was an IP22, IP28 or IP25). Couldn't you do a check for hinv -t cpu output for "R5000" to verify Indy R5k rath...

Re: WTB-Decent SGI Indy

Unless you feel you absolutely have to have an Indy I'd say broaden your search to include Indigo2 and Octane. They're a bit heftier construction, faster, more memory, more complete graphics (unless you have an Indy XZ, and even that is often slower than most I2s), and - most importantly - louder fo...

Re: Origin 2000 newbie

I'd go with the standards over a picture. The drive companies are making their drives to the standard, and the picture may be flipped some way you don't expect. That said, trust but verify is always acceptable - check continuity, solder wires on, then VOM it to make sure it's +12V.
