Toshiba bios password removal process is meant for use on Toshiba
laptops that you own or have had permission from the rightful owner to
remove the password. If any of these processes are done incorrectly it
may result in complete system failure or permanent system damage
(you've
been warned!).
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.
