Reset Unknown BIOS Password
Here is the link to generate a bios password to blank a system BIOS password when it is not known.
When you attempt to unlock a BIOS, usually there will be a System Number displayed (Example: System Number: G9WB613-BF97)
When you visit the site above and enter this system number, a code will be displayed. When this code is entered (and on most Dell PC you hold CTRL and Press ENTER) into the PC, the Admin password returns becomes blanked out. Bookmark this website as it might save your bacon someday.
