Some Toshiba bios passwords can be reset using the Key Disk.exe utility, to do this you need a 1.44Mb floppy disk. Format the disk using Windows and then with a hex editor, change the first five bytes of the second sector to 4B 45 59 00 00.
Then put the floppy into your machine and boot it up, you'll be asked for a password, just press Enter. Then when you're asked to set the password, type Y then Enter, this will get you into the bios configuration where you can then type in a new password.
Aside from the KeyDisk, you can build a parallel Loopback plug, this is a simple device that plugs into the parallel port of the machine and removes the password when you boot it up.
To make it you will need a 25 pin DB25 plug, take the plug apart and join these pins using some old cable;
Pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, and 18-25
Plug it into your parallel port and boot up your machine, the password should be removed as soon as it boots.
Note: This will work on majority of older Toshiba's (1995 – 2002) and obviously only ones that have a parallel port.
