Once you enter BIOS (Basic Input Output System you would need to setup your boot priority to your CD or DVD drive. Once you do that you will need to save your configuration and with your operating system disk in the disk drive restart your computer and then you will need to select Boot from CD or DVD, which ever type drive you have and your operating system setup should start.

GOOD LUCK!

Disabling a Forgotten Password

If you forget the system password, you will be unable to operate the system until disabling the password. Disabling the password involves going inside the computer and changing a jumper setting (twice) on the system board.
To disable a forgotten password, perform the following steps:

1. Turn off the system and remove the cover.
2. Move the jumper plug on jumper A to pins 2 and 3 to disable the password(s).
3. Turn on the computer. Powering up the system with jumper A set to the disabled position erases existing password(s). Before assigning a new system password, you must reset jumper A to the enabled position.
4. Turn off the computer.
5. Place a jumper plug on pins 1 and 2 of jumper A to enable the password features.
6. Replace the computer cover.

Using Passwords
Using passwords helps prevent your computer from being used by others.
Once you set a password and enable it, a prompt appears on the screen each time you power on the computer. Enter your password at the prompt. You cannot use the computer unless you type the correct password.
Make sure that only authorized individuals access your computer.
Establishing different kinds of passwords requires that other possible users know the proper passwords in order to access your computer or your data.
As many as three passwords might be needed for your computer: the Supervisor password, the User Password, and the hard-disk drive (HDD) password. When the Supervisor password is set, only the Supervisor password entitles you full control of the computer.
• User password
If a user password is set and Password on boot is enabled, a password prompt appears when you turn on the computer. Unauthorized users cannot get access to configuration data.
You can also use the user password to enter the BIOS Setup Utility, but once the Supervisor password is set only a part of the options can be set.
• Supervisor password
With a Supervisor password, you can get full control of the computer. It also can be used as a power-on password, the same as the User password. Also, when you enter the BIOS Setup Utility with a Supervisor password, you are entitled to set all of the options.
• Hard disk (HDD) passwords
Once an HDD password is set, you need to enter it to get access to the hard disk. You can set the HDD password through either the User Only selection or the User + Master selection in the BIOS Setup Utility.
Note: If you set passwords through the BIOS Setup Utility and you put your computer into sleep mode by pressing Fn + F1, the following describes the behavior of the computer when you bring it out of sleep mode:
• You are prompted to type the Windows log-on password rather
than the User password to resume operation.
• If an HDD password is assigned to any hard disk drive, the hard
disk drive is unlocked automatically when you resume operation.
To set a User Password:
1. Turn on your computer. Press F2, while the initial screen is displayed.
The BIOS Setup Utility screen opens.
2. Select Security, using the cursor directional keys.
3. Select Set User Password, and press the Enter key. The Set User Password window opens.
4. Choose your user password, which can be from one to eight
alphanumeric characters in any combination. Type it in the Enter New Password field.
5. Press the Enter key once to move to the Confirm New Password field. Retype the password you just entered to verify it.
6. Commit your password to memory, and press the Enter key.
7. Press F10 to exit.
8. Select Yes in the Setup Confirmation window.
Changing or Removing the User Password
To change the password, do the following:
1. In the Enter Current Password field, type your current password.
2. In the Enter New Password field, type a new password; then retype it to verify.
To remove the password, do the following:
1. In the Enter Current Password field, type your current password.
2. Leave the Enter New Password field blank, and then press the Enter key twice.
Note: Make sure the Password on boot is set to Enabled if you need the password protection at power on.
To set a Supervisor Password:
Only a system administrator will be able to perform this procedure.
1. Turn on your computer. Press F2, while the initial screen is displayed.
The BIOS Setup Utility screen opens.
2. Select Security using the cursor directional keys.
3. Select Set Supervisor Password, and press the Enter key. The Set Supervisor Password window opens.
4. Choose your supervisor password; it can be from one to eight
alphanumeric characters in any combination. Type it in the Enter New Password field.
5. Press the Enter key to move to the Confirm New Password field.
Retype the password you just entered to verify it.
6. Commit your password to memory, and press the Enter key.
Attention: You might want to note your password and keep it in a
safe place. If you forget your supervisor password,
Lenovo can not reset your password. You must take your
computer to a Lenovo reseller or a Lenovo marketing
representative to solve this problem. Proof of purchase is
required, and a fee will be charged for parts and service.
7. Press F10 to exit.
8. Select Yes in the Setup Confirmation window.
The next time you open the BIOS Setup Utility program, you will be prompted to type your password to proceed.
Changing or Removing the Supervisor Password
To change the password, do the following:
1. In the Enter Current Password field, type the current supervisor
password.
2. In the Enter New Password field, type the new supervisor password; then retype it to verify.
To remove the password, do the following:
1. In the Enter Current Password field, type the current supervisor
password.
2. Leave the Enter New Password field blank, and then press the Enter key twice.
Hard Disk Passwords
Two types of the hard disk passwords help protect the information stored on the hard disk:
• Hard disk user password
• Hard disk master password, which requires a hard disk user password If User only is selected and a hard disk user password has been set, but no hard disk master password has been set, the user must enter the hard disk user password in order to gain access to files and applications on the hard disk.
If User + Master is selected you need to set a master password and a user password both as the Hard Disk Password. Either of the two passwords can be used to get access to the Hard disk. Any change or removal to the master password deletes the user password.
To set a hard disk password:
Print these instructions.
1. Turn on your computer. Press F2, while the initial screen is displayed.
The BIOS Setup Utility screen opens.
2. Select Security, using the cursor directional keys.
3. Select Built-in HDD1 Password Select, and press the Enter key. A window for selecting User Only or User + Master opens.
I will send the rest in the comment section..hope this helps in some way...the Fang.

from the Toshiba support site

The BIOS and Supervisor passwords cannot be removed or changed unless you know the existing password(s). If you forget your BIOS or Supervisor password, you will have to have the password removed by a Toshiba Authorized Service Provider. Although the prompts for these two passwords have the same appearance, the passwords are set and removed differently. If both are set, the Supervisor password takes precedence.

I assume that the notebook will have a BIOS battery similar to a standard PC. If you are happy to disassembe it you may be able to reset the BIOS by removing the battery and/or locating the bios reset jumper

Another alternative is to If this doesn't work or you dont want to disassemble the PC, you can try to build the Toshiba Parallell loopback.

A lot of Toshiba computers remove the password when you boot it up with the loopback connected

It can be made out of a 25pin male connectors (db25). Connect these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, 18-25
