knocknut: Thanks, I tried the pccmos.com download. Did not work. I had been through it with Dell giving me a bunch of passwords and not go. I tried your other suggestion about disconnecting CMOS battery for five minutes. No good. I've ordered a replacement motherboard on ebay. I think that's really crappy that the original owner of a computer can get locked out with no effective fix from the manufacturer that will get around it other than replacing the MOBO. That's a major MOFU. Thanks again for your time.
