Re: removal of bios level password
Some laptops are passworded default at'oooo' or 'ooooo'.
The bios re-set is the 'JBAT1' terminal, from jumpers 1-2 to 2-3 for a few seconds and then back to 1-2 again, but where the terminal is exactly on your motherboard i do not know.
You may also try removing the bios didc shaped battery for 15 minutes or so, then replacing.

Heres a quick and dirty way to reset the password on the Toshiba Satellite A205 BIOS. Warning! You can only use these tips on your own Toshiba computer if you forgot ...
Hi That would be the BIOS password is open the ram
compartment and pull up the plastic sticker or whatever you want to
call it between the motherboard and the ram. There is a jumper called
"CMOS_CLR1" use a screwdriver to short out the pins and it clears the
The Toshiba BIOS password is stored on an EEPROM chip and removing the BIOS battery won't work. There is a hardware hack solution (a dongle) to remove the password.
Buy a 25 pin male D Sub connector and join the following pins together by soldering wires to these pins. Make sure the wires do not short against each other. The pins are numbered on the connector.
1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15
Plug the dongle into the printer port of your laptop and power up the laptop. Press F2 function key to get into the BIOS and then remove the password. Your laptop should boot up without the password and you can remove the dongle.
If removing the ROM battery (for a period of time, perhaps about 24 hours) does not help (and many people report it does not), you may need to take it to an official Toshiba distributor who will help you get past the password after you confirm that you are the legitimate owner of the notebook.
There is a reason for putting these controls on computers: it makes life difficult for laptop thieves, as it should. I only wish more manufacturers would do this. In the future, it would be nice if manufacturers allowed owners to verify their ownership (which they previously registered during machine initial system startup) online through a form, then download a file to a USB thumb drive that could be inserted during boot to allow the option of resetting (or unsetting) the BIOS password.
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
The problem is you have a BIOS level password installed. Laptop owners and computer departments sometimes install them in case the laptop is lost or stolen to prevent unauthorized users from gaining access.
