Here you go.

Solutions

The following descriptions only apply to Toshiba notebooks.

Version 1
1. Your notebook
2. An empty formatted diskette (720KB or 1.44MB)
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.

Version 2
Parallel port loopback
It's a simple device that you connect to your parallell port. A lot of Toshiba computers remove the password when you boot it up. The device 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

I removed the password from my Toshiba notebook a bit easier - you just have to find the BIOS battery - it's usually something in an open space as you unscrew the back of the notebook and mostly in yellow, so you can't miss it. Leave it unplugged for half a minute and bye bye, bios passwords :}.

Cheers,

Hi

I unlocked a lot of laptops and i can say that the hard part is to find that dam eeprom, after that is easy.
For old models before '99 you can unlock any laptop by removing his ram batery, for the new ones you have to do more then that.
Foe example, for al Toshiba you can build your own dongle, his schematic is extremly simple and you can find it on internet, for Dell you have to open the laptop, find the eprom, always 24C02, read the eprom and make backup afte this fill the eprom with FFFF, pack the computer and, voila, you have an unlocked computer, for vayo is the same, just fill the eprom with FFFF, if is not working fill with 0000.

Regards

Fludor
