If you have tried the parallel key and the USB key, you can try to remove all power from the system and one line at a time ground all the pins on the security chip.  Some people have had success with that.

Officially you can get your password reset through any Toshiba Authorized Service Provider, provided your laptop hasn't been reported as stolen.  A local ASP can be found using this locator tool: http://pcrepair.toshiba.com/

You can try to build the Toshiba Parallel loopback. To make a simple device that you connect to your parallel port, a lot of Toshiba computers remove the password when you boot it up. The device, named "loopback" by some, could be made out of any parallell wire with 25pins connectors (db25). You should connect these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, 18-25.

If your toshiba has a floppy drive, some models use this keydisk to reset the bios password: http://www.cgsecurity.org/keydisk.exe

My reference material indicates that the 2100CDS should work with the Parallel Loopback dongle.

Here is a page with build description: http://www.plasma-online.de/english/help/solutions/bios_password_toshiba.html

Make sure you have built it properly and you don't have the pins backwards.

Have already built the Dongle as you have described, no joy, also tried the floppy version (Change to ASCII "KEY" on second sector)

Which is the security chip?
