Re: Dammit

Hi Jan-Jaap, Read a few threads on Dallas chip expiry issues. Is this SGIs equivalent to vintage Macintosh leaky capacitors? Not a matter of if it will fail, just a question of when it will fail. Every component has a certain life expectancy, and everything will fail eventually. I'd say leaky caps ...

Re: Dammit

Since you have to initialize the 4D PowerSeries NVRAM by hand, I might as well leave this here: .data:B06301D0 nvram_defaults: .word aNetaddr_1 # DATA XREF: init_nvram_params:loc_B0600B5C .data:B06301D0 # init_nvram_params+4C ... .data:B06301D0 # "netaddr" .data:B06301D4 .word a192_0_2_1 #...

Re: Dammit

Well, once you key in the relevant NVRAM parameters, it boots and flips polygons like it's 1991 :D

Dammit

Another Dallas bites the dust:

I'll have to do something because the PowerSeries PROM doesn't know 'resetenv'. And with a garbled NVRAM it doesn't boot.

Ah well, it lasted more than 25 years ...

Re: SGI Origin 2400 Rack cabling help

A cool, I see, I seem to have one of those in each module. So I gather these are to connect to external SCSI devices such as disk arrays? Correct, but beware they are high voltage differential SCSI. I think it's possible to configure channel A in SE mode. I also have some other cards, they seem to ...

Re: SGI Origin 2400 Rack cabling help

That's a breakout cable for the quad channel SCSI XIO board. One A/B cable is for two channels.

Re: Onyx rack start-up problem

Oh, since you didn't realize the serial ports are wired in a non-standard way: beware of high voltage differential SCSI inside the Onyx. That is not the same as low voltage differential (LVD) SCSI. If you connect an SE or LVD device to a HVD bus, magic smoke will escape. Normally, one of the SCSI bu...

Re: Onyx rack start-up problem

3) Do I need any software on hdd or other media to perform the "Diagnostics"? The Onyx performs fairly comprehensive diagnostics when it is powered on. "Big iron" diagnostics are not included with IRIX, like for the workstations. The diagnostics version and the IRIX version it i...

Re: Onyx rack start-up problem

1) What does it mean "sysctlr_getserial: got bad response char: '-1'" While I could guess, I don't know what that means. Some problem with the System Controller... does it store a serial number in its Dallas timekeeper? Correct. The system serial number is stored at least twice: once in a...

Re: C-Ray FP/CPU Benchmark Test Results

Btw, did you know Phoronix adopted c-ray as one of their standard tests? It sometimes crops up in CPU reviews on Anandtech and elsewhere. :D Hmmm. c-ray is a rather trivial program that runs entirely in L2 cache of any CPU made in the last 20 years or so. So while it may say something about CPU per...

Re: Maintaining Hardware / fesability of keeping hardware running

However, I will still end up by owning most, if not all of the SGI's produced, preserved in a functional state for collectors purposes That's more or less what I pieced together, though I certainly didn't start with that plan in mind. And in the process of acquiring all that hardware I ended up wit...

Re: Onyx 10000 deskside keyboard issues

Try to replace the keyboard, mouse and the cable which connects them to the system? Alternatively, test the keyboard and mouse with a compatible system (Indigo). At least you'll know whether to blame the system, or the peripherals. I believe the keyboard controller is on the IO4 board, but there's a...

Re: Maintaining Hardware / fesability of keeping hardware running

Which system with good performance do you think would probably be the easiest to keep going far into the future? Define "good performance" ;) Seriously though: if a 5 year old MacPro crushes an 8 CPU Onyx 350 by an order of magnitude , how do you think any SGI will compare to a contempora...

Re: Maintaining Hardware / fesability of keeping hardware running

I've had my fair share of these problems over the years. I too used to own an Onyx that would eat one or two boards every year. I must have changed most of the system over time and it just would keep failing. I hated that thing. In the end someone gave me an Onyx IR and this one never had a single p...
