The collected works of tillin9 - Page 1

You pretty much need libc6 to do anything, so my guess is its a version issue. Ubuntu is actually very bad about this, frequently updating their libc. I'm on Debian Etch and can't use packages compiled for newer Ubuntu setups because it was compiled against a slightly newer libc. To see what version you have use dpkg -l

tillin9@Shiva$ dpkg -l libc6

ii  libc6                        2.3.6.ds1-13                 GNU C Library: Shared libraries

Then check the libc needed by the package. An apt-get update, apt-get libc6 might just update the package, but I'd apt-get dist-upgrade to make sure you don't cause any more dependency problems (libc should be backwards binary compatible, but sometime isn't).

Finally, assuming your connection isn't to blame, might I suggest using a different mirror in /etc/apt/sources.list? I'm sure you can find a list of mirrors on the Ubuntu website.

Hope this helps.
I downloaded the latest .deb of limewire and got this error message:

limewire-basic depends on libc6 (>= 2.4-1); however:
Version of libc6 on system is 2.3.6.ds1-13.

Libc on fiesty is (2.5-0)

What version of Ubuntu are you running?
Also, Debian and Ubuntu are not static distributions. Apt-get update, apt-get dist-update will keep your (stable/ testing/ Ubuntu revision) but will update the packages that have changed.

EDIT: Looks like you're using Dapper? If so, you need to upgrade (or at least download the .deb of the newer libc (edgy has 2.4-1, so it should work)) to use that version of limewire.
If you're on 6.10 (Edgy) but have not run apt-get update, apt-get dist-upgrade in awhile, doing so will fix your whole problem as Edgy is should have libc6 2.4-1. Both Debian and Ubuntu routinely compile packages, release them, then upgrade them within a distribution. Doing an apt-get dist-upgrade will not move you to fiesty. It will, however, have a lot of updates if you haven't done this in awhile. An apt-get update, apt-get install libc6 might have fewer packages. However, the bigger point is you should run apt-get update, apt-get dist-upgrade regularly (I script it via cron on my Debian stable servers) to get things like security updates.

As far as the link, it looks like Ubuntu's servers are getting hammered, the whole package search section is down. The google cache: ... cd=6&gl=us also shows the individual package link is down. Maybe the package mirrors are down too?
As much as I'm a Debian fan myself (100+ machines running Debian, okay most are work boxes :) ) Debian Etch would have the same problem with Limewire. The Limewire devs used a very new libc. I only have 2.3.6, it needs 2.4-1. The testing (Lenny now), unstable, and experimental are actually all 2.3.6 also. There are some 2.5 libc6 packages in the works, but nothing on the mirrors.

My opinion is to wait for the Ubuntu servers. Using the Debian unstable package: would also be a possibility (I've used Ubuntu packages on Debian before), but I would think twice if this is more than a test box.

EDIT: Yes, so you're on Dapper. You said above you were on Edgy (6.10). Dapper only has an older version of libc6. Sorry if any confusion was on my part.

You might want to swap dapper for edgy in your /etc/apt/sources.list, then run apt-get update, apt-get libc6 and see what other packages it wants to pull along if the Ubuntu mirrors seem to be responding better than their web page.
Hey, no problem.

I'm on Debian Etch, but your /etc/apt/sources.list should look something like this:

tillin9@Shiva$ more /etc/apt/sources.list
deb etch main contrib non-free
deb etch main contrib non-free
deb etch main contrib non-free

deb etch/updates main

But with a dapper in there instead of etch as that is your release name. Your mirrors will also be different. Anyway... to change distributions you just substitute the release name in this file. For example if I wanted to move my machine to testing (Lenny) I would swap etch to lenny then run apt-get update. You would swap dapper with edgy. The nice thing about apt, is you don't have to upgrade the whole distribution. If you're on Debian stable, but really want something that's only in testing, you change your /etc/apt/sources.list file, apt-get update, apt-get install packagename (it will automatically install the updated dependencies), then swap it back and run apt-get update. Apt is smart enough to leave those updated packages alone when you run your automatic updates. Granted a mixed distribution is inherently less stable than a pure one, but the vast majority of the time it works. This is essentially the same thing as downloading and manually running dpkg -i on the Dapper or Fiesty libc6 package but allows you to get the package through the Ubuntu mirrors since the http site seems to be down.

So what your are saying is that if I change the locations for edgy packages and then run update manager, I will upgrade the system to edgy?

Yes. If you were to change those to edgy, the run a full apt-get update, apt-get dist-upgrade you would update everything to edgy. However, if you just apt-get install libc6 you'll only upgrade libc6 and dependencies to the edgy versions. I'm not sure how good Ubuntu is about going from one whole release to another. I remember I had one of my home machines set to stable (instead of Woody, rather stupidly) and when Sarge became stable instead of Woody the automatic updates migrated the machines over to Sarge (since Sarge was now stable) without a single issue.

As far as libc-2.6-7 not being on the mirrors, these things are not static and when I wrote that it wasn't. My comment still stands that the Limewire devs probably shouldn't have used such a new version when a lot of users don't have it. Using a testing version where things break isn't necessarily the best solution.

EDIT: While I PMed yesturday, the message seems stuck in my Outbox.

Anyway... I'm in Middletown (~30 min away I believe) and can drive over this weekend to pick it up. However, I wanted to check if it was an Octane or Octane2, and what condition the skins were in beforehand.

Thanks in advance.
If the skins aren't too badly damaged I can always do my restoration trick. I care more about the internals as I might want to upgrade the processor/ RAM, so that's good to hear. Video being IMAPCT is perfect, as Linux can't do VPro. I do sort of want everything, with the V6 being the lowest on priorities.

I happen to have a Fibre issue at work that this guy could really help on debugging. I have plenty of cables cables and GBICs or miniGBICs (if the card needs them), so that's not an issue. The model of the fiber card, if its in a PCI shoehorn, or if it needs an SGI DB9 to optical (MIA) would be useful.

Assuming I end up with it, I won't need the Fibre array after about a week's worth of testing (mainly to debug the card so I know it isn''t a problem on my end when I connect to the University computational SAN), so I'd be willing to pass it on to someone who does. I may need to hold onto the card depending on model and other issues. If its a X9-FC-2POPT-B I'd be really happy.
Still interested. As I said above, if I do get it, I'll gladly pass on the array once I'm done with it (a week tops). Shipping to Texas will probably be expensive, though.
PM sent.
I2C is the protocol used by sensors to let the BIOS know things like temps, fan speeds, and supply voltages.


Code: Select all

12V   Wait Pwr  10%  10.80/ 13.20  20%   9.60/ 14.40    0.19


Code: Select all

5V aux   Wait Pwr  10%   4.50/  5.50  20%   4.00/  6.00    5.12

looks like the issue to me. You seem to have a problem with your PSU adaptor (i.e. not all rails are getting power).

If you're sure the wiring is okay, you may have damaged your voltage monitoring IC.

Finally, since the video card does have an I2C connection to monitor fans and voltage on most newer cards. It may be on the Fuel this system is integrated to the central I2C controller and not on a secondary one on the XIO bus, so the lack of a video card means an I2C error. Or the PROM is smart enough to sense the secondary chip. You may be able to disbale this somehow.
I must admit I first learned how to program in BASIC. When I was little the first thing I wrote (well, that I remember) was a game in text mode graphics on an 8088 where you played the Dinosaucers figthing whoever they did in the cartoon (it was a long, long time ago). While I think its best to learn C before diving into other languages like assembly, C++, PHP, etc. if someone is too young to learn C then teaching BASIC might be a good idea. You get a lot of the math and simple programing concepts without all the complexities of pointers, scope, datatypes, etc. that are critical to being able to use C for anything more than hello world.

Plus BASIC->PBASIC (Parallax Basic Stamp language) is a great way to learn about electronics and microcontrollers without having to know assembly if you ever decide to go that route. That's not to say one shouldn't learn assembly, my knowledge of assembly has really helped my C (and other language) coding so I think that its a vital part of any programer's study which is sadly in contradiction to the Java only curriculum of most CS courses (at least in the US).

If you have an old PC, the BASIC interpreters IBM made were quite nice (and the manuals very well done). Windows 3.1 era machines came with Microsoft's QBasic (its on Windows 95 and 98 CDs even though its not installed by default). I'm fairly sure that DOS-box could run all this in emulation on a UNIX or XP machine if you don't have the hardware.
Anybody try a newer ATIon the O2 with > 7.1? I got my legacy IO API working, and sees the card, but still pukes. I haven't had time to play around with newer builds, but have been constantly told they're re-arranging their PCI subsystem.

If anybody has some low-level graphics or even x86 and MIPS assembly (I'm seriously lacking on the x86 side) programming experience, I'd love for them to take a look at the Int10 + ATI + Legacy IO path, its very possible that the Int10 routine needs some MIPS/ O2 specific code. Int10 converts x86 video BIOS to platform assembly to POST the card which is a non-trivial task. However, I ported the underlying kernel API that lets see it as a video card (find registers, pull the BIOS rom, etc.). See: viewtopic.php?f=8&t=13680&start=60

Note, with a 600 Mhz processor compiled with the proper RM7K optimizations, the O2 makes a half-decent desktop even without 2D acceleration. With it, It would be on par with a high end PIII, maybe better with ICE patches and X and KDE compiled with optimizations.

Also, from the Linux-MIPS mailing list, somebody just got a patch to get intelligent PCI extenders working on the O2. I.e. you plug one of those into the single PCI slot and it provides the necessary bridges to get 3 PCI slots. A little hacking with one of those, a video card, and a small USB PCI could give you all the IO you'd need.
zahal wrote: BTW, What's the R12ka optimized port status?

As far as I know Linux will run, but crash after 5min-hour because of the R10K cache issues. Octanes have hardware to prevent corruption and BSD uses a whole other set of DMA routines which is really what prevents Linux from being stable. NetBSD and OpenBSD should have R10K and R12K O2 ports, but the work done for those OSes don't directly apply to Linux. The best info. on the subject is here: ... ssue.shtml The same site has some patches, but work is slow...

As far as Linux/ Irix on a single drive, that's a walk in the park. You just need to use arcload (or the more complex arcboot) and supply the right partion numbers and kernel names. Tell it to boot one by default and if you want another OS, interrupt the boot sequence and type boot Linux or boot Irix (or whatever you name them). I do this all the time to control what kernel I load and whether to load my Debian or Gentoo partitions. I actually haven't tried Linux/ Irix dual boot since I have an R12K O2 that runs Irix and I use my 600 Mhz one purely for Linux, however, I know its possible. You may need a larger hard drive (or to resize your volume header since its advantageous to put both kernels, arcload, and config files there) to do this. I'd highly suggest trying the Gentoo SGI Live CD first though.

If you want to try with arcload, I can help. Arcboot is a whole other issue. Gentoo uses this instead (by default), and it doesn't seem to properly overwrite the OSLoadPartition PROM setting so you either need to change PROM variables before booting (annoying) or do some major trickery to get Irix to load. See this (rather confusing) thread: ... +boot.html

As far as power, I'm okay since my 600 Mhz processor draws < 3 Watts (it probably could run without a heat sink). Trying to add a modern video card on an R12K probably isn't the best idea, but for heat issues rather than power. Open the case of your running R12K and feel the giant heatsink after 30 minutes, rather warm is an understatement.

The fastest PCI ATI card you can get (at this time) is an X1650 and still only draws around 30 Watts full load, which is the max a standards compliant PCI slot can provide. I know the BFG PCI says 250 Watt, but I think this is more of a cya number since most power supplies inflate their wattage. Also, the PCI board doesn't have a power connector so it must be under 30 watt, like the X1650. As far as the numbers on the box go, I've run P4s off high quality 150 Watt power supplies when the box said 300 minimum (and drew a ton of flak for that) but using a Kill-A-Watt measured the real peak load of that system to be closer to 135 Watts. Since an O2 can also accept a secondary video card and video capture board, I'm fairly sure power supply isn't an issue unless you really overdue it. Your PCI extender may need to tap into the power supply directly if you plan on using multiple bus-powered USB devices, but I'm sure its doable, even on an R12K.

Finally. you won't think this from the monster heatsink and how hot it gets, but the R12K @ 400 Mhz is only a 20 Watt processor (according to wikipedia). However, I'm fairly sure about this number since Hennessy and Patterson mention the R14K @ 600 is 17 Watt and that number is also in the Wikipedia chart. That means 150 watts for all the other components in an O2.

Anyway... sorry for being long. :oops:
Seems silly, but why not put the table inside the <form> tag? You can then either have 1 submit button or 1 per line and then do server-side parsing to let the user know more data is needed (or not, thinking like an online order form). The only thing is I'm assuming you can use HTML 4? If you just didn't think of this sorry, but having to use forms only inside of tables seems like a Netscape 3.0 support decision or something to me.
Using pure HTML 4.0 and CGI I'm 99% sure its not possible. I mean if you have multiple forms per page, and submit one, does the server get any info on the other form's attributes? No, its like they're not even there. This is an HTML issue, not a server-side issue. If you can go XML 2.0, XForms lets you do data binding, so two Xforms can share the same attributes with some work since the document has a singular namespace.

If you have to stay HTML, a hack would be to shadow every form's input elements in every other form and use Javascript to toggle all the hidden elements when one real element is toggled. You may be able to accomplish the same via CSS 2.0+ since CSS lets you toggle names elements properties - this is how you do CSS only rollovers and menus, essentially you add text to a hidden element that is sent, then parse it on the server.

Honestly, though, I think it would an order of magnitude easier to just put them all in one form even if it means modifying the legacy code. I mean how hard it is to add a server side variable to not echo the <form></form> tags per line (I'm assuming your code generates each HTML form and checkbox via a function in a template.) and stick one around the whole nested table structure. Maybe a few lines to change the naming scheme, and you're done as each submit now submits the whole form.
Wow, that cryptomemory is some neat stuff. My first instinct was that you could get a 2K SEEPROM and fake it, but I don't think thats possible since the chip doesn't use I2C protocol. A small PIC probably could work as an easier to implement stand-in.

Assuming SGI didn't just use it as PROM and uses the encrypted ATR protocol, you'd need to at least need to log the datastream sent to the module and do some cracking to figure out what the right bits are to send. The encryption seems to be 64-bit, which could be rather painful (DES is only 56) depending on the implementation.

Probably best to call the company and ask for relicensing, if possible.
I only have ATI cards. Specifically I have a 9700 Pro and X850 XT which are about 75% supported via the open source reverse engineered driver. I.e. I can do 3D + compiz, just not as well as my hardware really should.

I'm willing to except limited support and/or less features, but would like to give this a try. Can I? Or do I need an nVidia card? I'm probably not going to buy a new video card for this, but would like to try.
Sorry, I know you have said development would focus on nVidia drivers (and I agreed in the other post that the proprietary fglrx drivers are rather poor) and the request of graphics card in the invite made me think I'd get a "ATI users are out of luck" response. I'll gladly give this a try if I can.
Honestly, I think its cool, but kinda insane. I briefly thought about doing something similar as I have a stack of 2Gbit SFPs leftover from work and a bunch of PCIX fiber cards which are supported under IRIX/Linux/BSD. The main thing which stopped me is that electricity here is very expensive and a full-fledged computer (as a gateway/ firewall/ web server), with a fibre switch and wireless access point consumes a whole lot more energy than my WRT54GS. The heat/ noise factored in there a bit as well.

I know your network has had issues, but trying to "standardized" on fibre is a bit of an oxymoron. Fibre is a very proprietary media and without long distances, it offers little benefit to gigabit often at much higher cost.

I know it lacks the cool factor, but if I were you I'd sell a good portion of that fibre and purchase a good 16-24 port 10/100/1000 fanless gigabit switch with a 1000ft spool of CAT6, a crimper, and bag of RJ45 connectors and maybe some 100Mbit network cards. Ideally you can use expansion cards to make your 10Base2 machines into 10Base-T ones but media convererts do exist and are cheaper than ones to fibre.
Have any LC-LC? I'll trade a bunch of roughly 1000ft CAT6 lengths for a few LC-LCs. We're actually in the process (we'll its somewhat constant since we routinely add new machines) of adding new cables for the research clusters. University IT gave us all the leftover cable they were going to throw out a few months ago and we have more than we'll ever need. I'm sure I could get more very easily as they are horribly wasteful. I can't find any links for anyplace that sells bulk cable like that, but it comes in on trucks via 5ft high plywood spools.

Anyway... sorry to be a downer.

Fibre is cool and can be fun to play with. I liked getting to use 2Gbit links between our main cluster switches at work. However, while all was fun with the same model Linksys switches, trying to get them to interface with the University's Cisco gear was absolute hell. I'm not saying get rid of all the fibre, a single high speed link between two machines like your main workstation and fireserver is fine. Just realize its not something really possible to make a full home network out of without a lot of pain and money.

Also, the sole benefit of using fibre at work besides uping our headroom (we haven't yet maxed out gigabit) was to decrease latency, which it did for longer hops on the network by roughly 60%.
As far as the Mac Intel vs. PPC issue, the only time I've ever found the G5s to be faster is when the software uses Altvec optimizations and hasn't been re-written for SSE. This was a big issue with Final Cut before my old boss got her new software, that the new Intel Macs took 2 minutes longer to compress things than the old G5s. With proper software support, most encoding is now sped up by > 2x.

The dual G5s pump out so much heat, especially when used heavily for video work, I'm not surprised by the "tempermental" quality of the quads.

Finally, a 30" display isn't for everyone. I tried the 3007wfp and couldn't use it, text was too small if I sat at a comfortable distance and I had to move around too much if I got close enough to see. I found the 24" a much better fit, plus it was about $1600 cheaper since I would of had to repace my video card also as my aging ATI can't do dual link DVI. You can get a 24" E248WFP off of Dell for around $410 but its crap. My boss has one and though he loves it, I think the image quality is exceedingly poor. Basically the image head on looks like my 2407wfp if I try viewing at 170 degrees, a little fuzzy, poor gamut, poor contrast, poor brightness. I got my 2407wfp for $540 and think the extra money was worth it. You might want to try for a 2405wfp since its basically the same panel (just doesn't support 1080p via component) and you can get it cheaper.
I've managed to upgrade my Octane2 and while Linux runs like a dream on it, sadly I think I need to re-install and/ or upgrade IRIX to deal with the newer processor. While I know I could try to do it via network, I think a CD drive would make this task easier and help a lot with other software installation and just day-to-day use. A couple questions:

1) My question is what type should I get? I assume any 68 pin and 50 pin w/ adaptor will probably work but always helps to double check.

2) Did SGI ever make any themselves? I won't mind a matching or branded enclosure.

3) If not, anyone know a model that's reasonably quiet? I used one on someone else's Octane which made almost as much noise as the Octane.
Sorry, I guess I didn't quite phrase this quite right. :oops: I'm more interested in the enclosure. I have a spare Plextor 12/10/32 known to work with SGIs, and if all else fails, I do have a spare O2 CD-ROM I could use.

I'm surprised I never saw a picture of the SGI branded one. Anybody who has one mind snapping one?
Neko, thanks for the pic. Looks a little more plain that I expected. I happen to like my Zip650 on top of my Indigo (although connected to my PC) since its a matching purple, and My Jaz next to my Octane as they're both green (I'm probably the only one with all the insides of an Octane2 in a set of green skins).

Naw, I still have an old dirty 6.5.11 I didn't install. I have 6.5.22 overlays, but never got around to using them on the Octane.

Can I do an install over network from an O2's CD? That would work.
Care to share how it was configured? Or is this just a normal network install?

Besides iSCSI, I can't think of a good way to share the device.
Um... Why not just put a copper GBIC into a regular Fibre hub? Something like this: ... dZViewItem
Quad GigE PCIX/PCIe cards do exist (and actually depending upon driver make bonding easier too), making it only need 6 expansion slots. Some of the motherboards with those slots also have built-in U320, I'm thinking of the Tyan Thunder S2676 (3 PCIX, one PCIe, 2 PCI which is the heart of one of my servers at work) which takes it down to 5, so that means 2 quad GigE (say PCIX), FDDI, Thin Net, and Token Ring PCI. Doable, but not easy or cheap. Of course one could also imagine the server being some form of Origin :D or more realistically not having 3 bonded GigE lanes to your fibre channel or 3 bonded 100 Mbit to your router.
Fu, a good topic for the wiki is the 1600sw, considering how many threads come up concerning them. Things like the different multilink adaptors, how the prototype differs from the production model, and mentioning the "Radius Artica" variants would also be welcome. Pics would also probably help as well as a link to the Neko 1600sw gallery would be good too.

Also we might want to add mention of the clear O2s on the O2 page, and a pic of each of the O2 old, new, O2+, and clear skins.
Get well soon Neko!

I'm not sure if Neko's clear O2 was the one for sale on the forum awhile back. I.e. This one - viewtopic.php?f=4&t=14580 The pics on Neko's hinv thread viewtopic.php?f=14&t=14786 don't show the spot where the crack would be.

I almost bought this one - viewtopic.php?f=4&t=14626 , but it was missing the CD bezel and I decided to spend the money elsewhere.

I also seemed to notice 2 clear O2s for sale / trade a long time ago when I was first getting into SGIs. There should be a bunch of them, I'm guessing somewhere between 16 and 40. Though sadly some have not been well cared for, which is a real shame.

Sorry, you can somewhat tell what my #1 wanted piece of SGI kit is, i.e. a set of mint clear O2 skins.
I think 139 and 278 are both right, though 278 is more correct. I counted the pins on one of my modules and got 139 per side, so 278. My 128MB modules are double sided, but some Kingston 64MB modules (I happen to have two) are just half a 128MB module and 139. At the very least 239 is wrong.

Possibly a picture for the wiki might be helpful, I'll see if I can get some shots of my modules. I have 128MB (SGI and Kingston), 64MB (Kingston), and 32MB (SGI).

Also, how does one add pictures to the wiki? I can't believe our O2 page doesn't have a picture of an O2! I'll volunteer pics of my cube style O2 for the old style pic. I believe there are some floating around in the forum in my restoration thread.

We also might want to mention the SGI badges in the Indigo, Indy, and Indigo2 wiki pages. I'm not sure there was a badged O2, was the WebForce O2 marked differently?
Great work! I really like the changes you made to the O2 page with the processor and RAM lists. Two minor issues, one the tables style doesn't match the others in the wiki (personally I think yours is nicer and the others should be changed), and the SS/DS (Single-Sided / Double Sided?) should be clarified.

Couple of fun facts to add (if you have time before me) on the Indy and Indigo RAM info from the SGI specs. since I came across some incomplete and incorrect info. when looking for RAM for my machines as shown in viewtopic.php?f=3&t=17275

Note, the Linux-MIPS site has a lot of specs. which might contain useful information for the wiki.

I like the VPro page and think that's the way to go. Ideally the Impact/ MARDIGRAS boards should also have a page and the sections in the Octane / Indigo2 pages (half the Indigo2 page is on IDing the video options) should be contracted. Also, do you happen to have the PV, Digital, Compression, and Analogue/Digital video option info? I think there is a lot of confusion on this. Personally, I happened to run into this ... dZViewItem on eBay and was wondering exactly what it was.
Just cleaned up the O2 page. The 139-pin number wasn't changed, 278 is correct (especially as used in the article for the motherboard slots), only single-sided modules can even be thought of as 139. Also added the single-sided/ double-sided. My criticism was that SS/DS isn't a universal abbreviation for single-sided/ doubled-sided (well, at least it wasn't immediately obvious to me) so the first time it comes up things should be spelled out completely. I also changed a little of the wording to use better parallelism, etc. and clarify that 3rd party RAM may not follow SGI rules (such as SS/DS and color coding), mainly to prevent posts of "My RAM isn't like that in the wiki! The wiki is wrong!" I also mentioned that DIMMs must be installed in descending order. I.e. after the largest in Bank A, an equal or smaller size kit must be in Bank B, etc.

Finally, I believe that not just high-density DIMMs, but ANY type B module requires PROM 4.4 or higher. This is why 256MB is the maximum memory allowed before 4.4. However, the existence of a Type A 128MB modules is confusing. Anyway, I didn't address this until I was 100% sure.
Yea, I also cleaned up the Add-On options since previously it looked like there was just the dual-head and flat panel (1600sw) options, turns out there are three, there is also the Indy / 1280 Presenter option. I also managed to figure out how to do pictures in the wiki so as soon as I get my camera back (friend barrowed it for spring break) I'll get the images I mentioned up.

I agree the How To section needs work and I like the idea of making it make sense with How To ________ where the blank is the article title. Cleaning that up will take some work though as a lot of those pages need work as well. The biggest issue here is with linked articles, since if other pages link to those pages, changing the titles will break things. Since I'm still new to wiki editting, is there anyway to see all linked pages?

Finally, feel free to clean up my grammatical errors, I've been busy writing papers lately so I have this in mind, but I'm an Engineer not an English major :P so there will likely be mistakes.
Cool, I'll add it to my list of things to do. All the recent OSS progress has really made me wish I had more free time.

Also, what's up with the O2 case on the linked page? Is that an OpenBSD logo by the O2 logo or some kind of extra button hack?
Seriously, why the Linux hate? Yes, I'll third that the Octane's hardware works much better under IRIX and that any of the really unique stuff like video capture and accessories probably don't. However, the original question was has anyone gotten Linux to work on their Octane. The answer is yes, I have. Kumba (the Gentoo-MIPS lead) and Frapazoid are two other forum members who I know have as well.

The Octane isn't quite as crippled under Linux as some posters have suggested. Impact based cards have some degree of X acceleration. The VPro cards don't, however. The audio works, onboard SCSI works, the Octane tape drive works, and PCI shoehorns and card cadges work (and support a large amount of hardware IRIX doesn't like USB cards). I'm not 100% sure on the status of the XIO peripherals, some cards work (anything that internally uses a PCI bridge) including SCSI, Gigabit, and Fibre Channel. The only other thing I remember testing was the SCSI floppy, which didn't work. (Actually caused constant printks so I had to pull it).

Somewhat unfortunately, all of the support is currently only in Gentoo. I highly suggest the Gentoo SGI Live CD. If you have a SCSI CD-ROM, just burn it and boot. If you like what you see, you can go from there. Actually read the readme since its not a normal ISO image.

Getting the kernel patches into Linux-MIPS and mainline is a goal of one of the developers on the mailing list who recently added a lot of SGI support (audio drivers for O2, Indy, and Indigo 2, among other things). Also, I'd like to point out that 2.6.27/28 will likely make the VPro issue moot as Linux will get kernel mode setting. That means Radeon X1550s (or whatever's the best PC PCI video card with Linux drivers around) for our SGIs. I'm fairly sure an X1550 is better than a V12 for the vast majority of video tasks.

Anyway... the point is that Linux support for SGIs is being worked on and will get better as time goes on.
Sorry, I think I overdid it. :oops:

Yea, even though I have a V12, I was looking around for an MXE for awhile for the sole fact that its the fastest card with Linux acceleration.

As far as the kernel mode setting, I haven't gotten that working on an SGI. Actually, the only really working support (as in testable with a released distro) right now is Intel's integrated graphics. If Intel actually releases Larabee, that should work too. Open source radeon support is going to be included in kernel 2.6.27 or .28 (I know the devs. that are working on the ATI side - and have told them about my plans to put a card in an O2) but the current stable linux release is 2.6.25 so we're a few months off. When I get it working, I'll let everyone here know. :D

@Chatuser - Yea, Debian's kernel is based on either Linux-MIPS or the mainline tree and hence won't work on an Octane. As I said, the necessary patches are in Gentoo's repositories. You can use a Gentoo kernel with Debian, but actually getting it on the Octane would be a little tricky. I'd recommend doing something like installing on an O2 or Indy (which Debian supports very well) then compiling a Gentoo kernel for the Debian disk and transplanting it into your Octane.
@pip - Seems like an arcload issue. I also couldn't get arcload (Gentoo's choice of bootloader) working, so I used arcboot (Debian's choice of bootloader) instead. Arcload is technically better, but more difficult to configure. The config file needs lots of nested { and } at the right places. At the time the nice wiki and help entries didn't exist, so you might have more luck now using the live cd and fiddling with the config.
You're not the first person to doubt my statements, but a big thanks for bugging the devs yourself and making a nice article for me to link to in the future. After your first responses I was going to go dig up all the old irc / forum posts where I hashed it out the first time, but now I don't have to. :D

What really surprises me is that more alt-arch people don't know / care about kernel modesetting. I'd think there'd be tons of embedded MIPS / ARM people who program devices with PCI buses (you'd be surprised that this is the majority, and most of the rest have PCIe 1x) who would love this. Just stick in a PC video card and have a low-end desktop environment for debugging / development instead of messing around with serial ports and JTAG.
While AtomBIOS and AMD/ATI's new open source policy makes this a lot easier for radeons, there is no reason why kernel modesetting won't work for all cards. Intel does it themselves, and I'd actually think older cards would have a lot simpler sequence than even an AtomBIOS parsing radeon routine. That leaves Nvidia to be reverse-engineered, and the Nouveau devs seem to think they can do it. ... &px=NjU0Mg

Also note that the radeonhd camp doesn't like AtomBIOS and bit bangs all the registers manually (although the higher ups got a little annoyed since it took much longer to support cards than the radeon folks which used AtomBIOS). AtomBIOS is just a nice interface for register table lookup allowing the same initialization code to reused. It doesn't actually initialize the card itself.

As far as to why, I got into Linux on SGIs since I needed to teach and intro assembly programming course. Most courses either use embedded MIPS devices which make learning very hard because they don't have enough power / memory to compile things themselves or try teaching x86 and confuse the hell out of everyone. In the first case, 9/10 times the problems aren't with understanding the assembly but with getting the program on the embedded device (cross-compiling, bricking the device while flashing) or being able to debug it (JTAG) when something goes wrong. I could just take the proper time to teach everyone how to do all that, but the department and university really look down on skills based classes. One intro to UNIX class was canceled for and I quote "Being too practical." Thus I got a couple of O2s, installed gcc, and was able to stick to Patterson and Hennessy.
