I have a powerbook ?G4?, with an unknown (as in I don't know what it is) OS on it. When I boot it up it asks for a password. I set the password ages ago to keep my brother out, and now I don't know it. Is there any way to bypass this password screen? On the message asking for the password it says something like "You need a password to run in scsi disk mode" These are not the exact words, but are the words that I can remember off the top of my head.
Also, I only get 3 tries to enter the password before it shuts down... Maybe this can help determine the OS?

Do you have your OS cd?

I know that on OSX you can remove a password using the cd, dont know about older mac OSes.

nope...
