Password reset on SGI O2

To reset a password on a SGI O2 this is what I had to do:


1. Insert cd for Irix 6.5 "Installation Tools".
2. Click "Stop for Maintenance" button.
3. Click "Install System Software" button.
4. Click "Local CDROM" button then "Install" button.
5. Click "Continue" button that pops up.
6. Choose "3" admin mode.
7. Choose "7" Shroot.
8. At the prompt type "passwd" and then your new root password.
9. Then just type "Exit" then "Return" then "Quit" pressing enter after each.
10. Answer "y" for yes when asked  to reboot.

You could also put the hd in another system. Mount the root filesystem and blank out the password. Now if you have forgotten your PROM/NVRAM Password (when you click "Stop for Mantenance" on boot and your prompted. ) then do the following:

 
1. With the system powered off, remove top cover of the system.

2. Find the black jumper on the motherboard and remove it.

    * On the Indy, the jumper is located next to the connectors where the power supply plugs into the motherboard.
    * On an Indigo2, the jumper is a little harder to get to. It is located on the motherboard underneath the 5.25" disk drive tray.
    * On an O2, it?s a little bit different. Remove the jumper that is located under the CPU board next to the black chip & replace
      it onto the 2-pin jumper slot right next to the memory banks. 

3. Once the jumper is removed, power up the system and enter the System Maintenance menu again.

4. When you try to enter the previously password-protected menu options, you should get this message: "Warning: Password jumper
   has been removed. Not enforcing PROM password"

5. Now enter the Command Monitor and use the resetpw command to remove the password.

6. Power off the system and put the jumper back onto the motherboard from where you removed it. The next time you start the system,
   the password should be gone.

For removing the PROM password from an Indigo, Origin 200 or Crimson system.

If you've lost your PROM password but can still log in as root, you
can zero the PROM password with 'nvram passwd_key ""'. If not, you'll
have to disable the PROM password via the hardware. On a 4D/35 or
Crimson, find the battery which maintains the nvram ("non-volatile
RAM") and remove it.

On a Personal Iris system, you have to open the right side panel. Holding the E-module (metal box containing the CPU & Graphics boards)
in place is one screw accompanied with the little sign underneath saying "Unscrew to Remove". By removing the top screw, the E-module
should be able to lean out. You will some cables plugged into the E-module. Remove the smallest 10-pin plug. This is the equivalent of
removing the black jumper from the motherboard on the Indy and Indigo2. Once, the 10-pin plug is removed, power up the system and enter
the Command Monitor. Use the resetpw command to remove the password. Once the password has been removed, power the system off and plug
the 10-pin plug back into the E-module.

I was going to use the O2 as a room heater (seriously this is all SGI's are good for anymore) but it was not warm enough. I had even written a shell script in csh to get the proecessor to 100% so it would really heat up. But in the end it was warm but not warm enough. Here's the script anyway:

#!/bin/csh
set num = 0
while ($num < 1)
set num = 0
end

Then I put the following line in /etc/rc2: "/root/toasty &" and it would start on boot and peg the procesor at 100%.
