Creating a BIOS Password Key Disk for Toshiba laptops
Many of the Toshiba notebooks allow you to bypass the BIOS password by inserting a "key-disk" into the floppy disk drive while booting. To create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it (under windows), then use a hex editor to change the first five bytes of the second sector (the one after the boot sector) and set them to 4B 45 59 00 00 (note that the first three bytes are ASCII for "KEY") followed by two zeroes.
Here is an example of what you are looking for. Your invdividual editor may look slightly different:

If you currently don't have a Hex Editor, you can download the freeware hex editor XV132 for windows

Once you have created the key disk put it into the notebook's drive and boot the laptop. When asked for password, press Enter. You will be asked to Set Password again. Press Y and Enter. You'll enter the BIOS configuration tool where you can set a new password.
