A friend came by the other day and dropped off a computer he found cleaning out his old house. It's a windows 2000 professional and it looks like it works fine but it asks me for a username and password. He said the computer's been there before he moved into that house so he wouldn't know how to start it. Is there anyway i can do about this?

LOL @ Abydos, yeah it can be really hard to explain something like this can't it

To aid the above, here is a basic demo of what to do, applying logic to what you see and following the above it should make sense, but don't take any notice of the pins I suggest here, just the principle of covering them.

To start the code I will use is x = a covered pin, o = is a a free pin with nothing on.
xxo = what you will first see, 2 pins will be covered and 1 will be free.
oxx = remove the jumper from the 2 pins it is covering, then move it over to cover the pin that was free, eg pins 1 & 2 were covered to begin with, then move it to cover pins 2 & 3, so 2 pins are covered at all times.
xxo = return the jumper to covering the way it was when you first saw it, failure to do this will stop the system from booting.

I hope with the great help above this completes the picture for you to achieve doing this.
