WHAT IS THE MASTER PASSWORD TO BYPASS THE BIOS PASSWORD
No such creature. Best way to resolve the issue is to locate the cmos battery and remove it for a few minutes after disconnecting the power wire and removing the battery. Also jump the cmos clear jumper - usually around the battery. After five minutes or so, the default bios will be there with no bios password.
