    Here's a link to a site where you can download "CmosPwd". It's free. It claims to be able to determine master passwords on machines such as yours. I haven't tried it so I can't vouch for it.

    CmosPwd - CGSecurity

    In the past, we used to simply remove the CMOS battery or disconnect it from the computer (often a jumper) and short the CMOS connections (also a jumper) to reset the CMOS memory back to its default. The usual default is no password. This may still be able to be done if CmosPwd doesn't work.
