So what you have is actually a SGI machine.  I don't know if this machine
has been modified from the original Silicon Graphics box, so I cc this to
linux@engr in the hope someone can comment on this.

Well, I would take them, though probably not all of them because I'm
already stockpiling MIPS boxes ...

Choose between IRIX and IRIX.  Someone else is working on a Linux port to
the Indigo.  No results yet, he has just started some days ago.  Since
you're interested in Linux for SGI machines you should also subscribe to
SGI's mailing list linux@engr.sgi.com via majordomo@engr.sgi.com.

The system is about a foot and a half tall and about 8-10 inches deep and
wide... (Square bottom rectangular sides...)    Bright blue with a pop-off
front that reveals the hard drives on the right and another panel on the
left... twisting the nob at the top of the left panel couses the panel to drop
forward and the CPU and Video card can be removed.  (The run from top to bottom
with clips on the top and bottom... pull forward on both clips and they slide
out.)

How much does IRIX cost?  And were can I obtain a copy...    I really need to
repartition these drives and start over... Becouse the system can't be shut
down properly becouse you need the root password to preform the shut down....
Consequently it's all messed up.    I plan on mounting it's drives in my
desktop and hoping that Linux can read the filesystem so I can clear the root
password....  Bye the way... Is there an easier way to clear the root
password?    And does anybody know what filesystem IRIX uses?

How do I subscribe to the mailing lists?  (Wow... Lot's of silly questions in
this letter huh? <G>)  Please CC to me becouse I'm not on you'r lists yet.

                Thanks guys, I really apreciate your help.

If its running Irix < 6.4 then read bugtraq archives for about 100,000 ways
to break root on your machine  8)

The best general scheme on a remote box is to stuff the disk into a machine
and without mounting it replace any disk block starting root:........:dfgkd
with your own password string.

5 minutes of looking on the net using tools like altavista would tell you.

  I don't have any idea how to do that, or even were to start looking for how
to do that...  Could you give me a place I could begin searching or reading?
