I finally found this on the web.
Does anyone know if it will work?

What do I do if I forgot my password?
There are two types of password protection in many computers:
The following suggestion will work only for passwords used before the operating system boots. If you set up a password only for booting the PC, in most instances you can enter the BIOS Setup to disable the password.
If you also placed a password on Setup itself, there is no "back door" password unless the computer manufacturer modified the BIOS to have one. The password is stored in CMOS and cannot be accessed by any other means. Contact your manufacturer for assistance. If you cannot contact your manufacturer, take the PC to a computer repair shop.
If you wish to attempt disabling the password yourself, you will need to erase CMOS. You should not do this unless you already have written down or printed out of all the BIOS Setup parameters, or if you are certain that restoring the Setup default values is sufficient for operating your system. Take these steps:
clear the CMOS (remove the CMOS battery until POST displays a "CMOS checksum bad" or a similar message);
re-install the CMOS battery;
run the BIOS Setup;
restore the correct BIOS Setup settings.
NOTE: it can take up to several days for the CMOS to go bad without a battery. This is caused by capacitance in the circuit. This charge can be safely discharged by using a 10k-ohm resistor, touched to the battery connectors for a few moments (while the battery is removed).
