Here's a neat trick I used at 2 am this Morn to get into a ATX Pentium to clear the password, I took a piece of file card and put it under the button cell battery for 1 hr to break contact, don't remove the battery, left it on for 1 hour, and up, I was into the setup!!! Of course, unplug all power supplies and use anti static procedures and you will get that old cranky Pentium up and running!!!!

For these, there is a special jumper to reset the password. The procedure for using the jumper variesfrom board to board.

Is there a way to
