Toshiba A215 locked out

[auntly]

ok anyone that can help me- i would appreciate it!! My toshiba satellite A215 is locked. I logged on to it, everything was fine, checked email, no problems went back to the computer after about an hour (it lockes automatically after so many minutes idle) and guess what, the password I have been using doesnt WORK!! if you click reset password it says to insert floppy or disk to reset. I do not have a disk with information stored for this. I have been researching possible issues, does this sound like a bio password problem or something else. thanks for your time.
