The seller is a computer dealer in the Midwest with a huge number of positive feedbacks. I presume the dealer got the computer in a mass buy of surplus computers from an industrial or government auction. With the CF-31 being introduced the CF-30s are beginning to be surplussed. I can easily see how a computer with a password-protected BIOS managed to slip by. Obviously, the dealer didn't know the password or it would have never sold at such a low price. If it were to have come from a private party, that would have raised my suspicions about it having been stolen. Of course, anything is possible.
