Step 5 had no effect, just localhost:/ root#
Hmm... ok, there are various options for that step depending on your version of OS X.... guess I gave you the wrong one.... but no harm done. I'll go back to the drawing board.
As I stated, I have my original install disks which I purchased.
I'll try to do some research and see. When the install disk boots up, on the very first screen, do you see any menus ? (drop down type, like the usual file edit etc. ones you see on OSX). Is there any option in those menus that looks like password reset ?
