Reset forgotten Toshiba 440cdt bios password

Can anyone please tell me how to clear a forgotten Toshiba Satellite Pro 440cdt bios password?

I put this unit into storage years ago when I got a (then new) Tecra 8000 and, now that I have rediscovered the 440, I'd like to give it away working (to my mom, probably).

I remember something from the old days about Toshiba's using a parallel port loopback plug to accomplish this. I attached one and booted but without success.

Thx much
Rich

Most Toshiba laptops and some desktop systems will bypass the BIOS password if the left shift key is held down during boot
Backdoor passwords

Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.

WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key over 100 times in rapid succession.

And here it is! This is what you are all waiting for!

The one and only way to bypass the Power On BIOS password
of a Toshiba Notebook. This method works on all models.

This is what you need:

1. Your notebook
2. An empty formatted diskette (720 kb or 1,44 mb)
3. A second computer (e.g. a DOS desktop PC)
4. A hex-editor (e.g. Norton DiskEdit or HexWorks)

This is what you have to do:

1. Start the desktop PC and start the hex-editor
2. Put the disk in drive A:
3. Change the first five bytes of sector 2 (boot sector is sector 1) to: 4B 45 59 00 00
4. Save it! Now you have a KEYDISK
5. Remove the disk from drive A:
6. Put the disk in the notebook drive
7. Start the notebook in Boot Mode (push the reset button)
8. Press Enter when asked for Password:
9. You will be asked to Set Password again. Press Y and Enter.
10. You now see the BIOS configuration where you can set a new password.

i did a google search for Toshiba bios password and all the above came up

sorry man, you need the keydisk as stated above, and the parralel key. they work in tandem to unlock the bios boot passward, you can sometimes find the parralel key on ebay, other than that you can find an authorised toshiba repair center to unlock it for you
