Bois Lockout

Toshiba Satillite A505D-S6968 I have been told that the bois has blocked me out .Askes for a password , witch I have no way of knowing sense I never made one. The OS (Vista) AMD64 2.3GHz-4Gb ram PC6400

The BIOS password is stored in CMOS memory that is maintained while the computer is powered off by a small battery, which is attached to the motherboard. If you remove this battery then replace after 5mins or so, all CMOS information (including the BIOS password) will be lost

try typing toshiba for the password.
