SGI Tezro

Se vi interessano le macchine SGI partite da questa url: http://www.futuretech.blinkenlights.nl/sgi.html si tratta del sito di Ian Mapleson, uno dei maggiori esperti e conoscitori di SGI che esista. Tra le altre cose è sempre disponibile a dare una mano per tutto quello che riguarda queste macchine. Un ottimo punto di partenza anche per ricercare hardware o software usato, visto che ha sempre qualche parte da rivendere... Un bell'articolo che parla di IRIX e di cosa è possibile farci oggi (contiene anche un link ad un programma che permette di avere una barra stile il dock di MacOSX) potete leggerlo qui: http://os.newsforge.com/os/05/05/13/131257.shtml?tid=10

SGI O2

SGI O2


Se vi capitasse di pasticciare la risoluzione del monitor e ottenere al riavvio un bello schermo nero....seguire le istruzioni qui indicate per ripristinare una risoluzione valida.

Avete comprato una SGI usata e non avete la password di root per loggarvi nel sistema? No problem, montate il disco come secondo disco in un'altra SGI che possedete, e editate (con VI o Jot o nedit) il file "passwd" che trovate in: /root/etc/passwd



Se un bel giorno la vostra O2 non dovesse partire più.... Leggete questa nota sotto..

Have you tried placing that little jumper in front of the Dallas chip into ON position?
After doing that, put the motherboard back in and connect the cables. When you connect the power cable, the machine should power on by itself. Then go to the command monitor and type "off", you should get some messages that the power supply didn't shut down, ignore those and pull out the power cable, place the jumper back into OFF position and you should have a working O2 This was all that was necesarry to revive my O2 (175MHz R10000) when it failed to power on one day...

 

Se un bel giorno la Fuel si mette a fare i capricci...tipo non partire o altre cose strane, spegnete il controllo d'ambiente:

From a runing IRIX:
l1cmd --scdev /hw/module/001c01/L1/controller env off

From the l1 prompt:
env off

Istruzioni estese per la gestione della L1 sulla Fuel:

Connect to the L1 port (serial port located on the motherboard) to see why the L1 is turning the machine off. Could be environmental monitoring.
You had a serial cable to connect to the rear of the box - same cable to connect to the L1 port on the motherboard - 9-pin serial.
You're not looking in the right place. Take the side panel off your Fuel and locate the L1 serial port on the motherboard, near the PIMM.
Sorry, I have no better picture currently available. What you can see i the SCSI connector and 8 cm to the right (not pn the image) you wll find the DB9 pin adapter. IIRC you need 19200/8/1/n for your terminal programm.
thought it is was 19200/8/1/n but you may need to experiment on the line speed.
The correct is 38400/8/1/n 
001a01 ATTN: XIO 12V bias low warning limit reached 10.500V
001a01 ATTN: XIO 5V high fault limit reached @ 6.630V
001a01 ATTN: brick auto power down in 30 seconds ...
If you feel like taking a chance you can turn off the env monitoring by issuing 'env off' at the L1 prompt. Then boot the system.

Vi hanno regalato una SGI ma non avete la password?

This is another one of those frustrating situations. You've just carted one of these critters home from a hamfest, you power it up, and it sits there and asks for a password. Now what? Well, if the NVRAM password hasn't been set (only possible for Personal IRIS 4D/30 and later systems, covered under HOW TO REMOVE ROOT and NVRAM PASSWORD ) you simply have to bring the system up in single user mode and reset the root password. For newer systems, simply enter the command monitor and type the command:

single

For older systems, you'll have to do it manually. First, boot up sash by typing:

boot dksc(0,1,8)sash

Then set the initstate environment variable to "s" by typing:

setenv initstate s

And finish the boot process:

dksc(0,1,0)/unix

This should bring you up in single user mode. Change the root password by typing:

passwd root

You can then bring the system back down by typing:

init 0

Or, alternately, you can finish bringing it up to multiuser mode by typing:

init 2

Note that once you power the system off, the initstate variable is cleared, and the system will boot using the default init state defined in /etc/inittab
