X-To: bugtraq@securityfocus.com To: BUGTRAQ@SECURITYFOCUS.COM In-Reply-To: X-Mozilla-Status2: 00000000 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 1 (boot sector is sector 0) 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. And that's all! Oscar Vila
