I too have been searching for answers on various sites and forums and none of the suggestions (including downloading XP drivers) worked.
This definitely works (at least for the Toshiba L300 Laptop anway).
Note: This will work on majority of older Toshiba’s (1995 – 2002) and obviously only ones that have a parallel port.
CG Security have a utility available that claims to work for a range of Toshiba bios passwords as well as the following machines; The utility also has the ability to restore, backup and erase/kill cmos.
Aside from the Key Disk, 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.
Then scroll down to the SATA option and change it from ACHI to Compatibility then exit saving your changes (F10) and then reboot your Laptop from the XP Operating System disk.
This 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.
Toshiba is aware of the problem and last I heard will fix the problem for free. Thanq for ur post i successfully reset the bios password in toshiba A100-294 motherboard, after that i entered bios and in security option i accidently changed TPM option (Disable) i activated the option.
Problem is you must send the thing in to them and do with out it while they do the repair. repair may take them over a week and you're stuck with out your laptop. When i restarted the notebook, Display is gone off now not working, How can i fix this plz help me? Unfortunaltely, it doesn't work on my model (A100-768 (PSAA9E)).
1) If you are lucky and haven't had the problem yet, up grade your BIOS ASAP. 2) If it has happened to you and you think you're stuck with a brick, Good news. I acually found C88 jumper un der the card, shorted it, but the computer still request a password.
You can fix this by removing first removing all power, then remove the plastic cover above the keyboard, removing removing the two keyboard screws. I also removed the hard drive to make sure th password isn't stored on HDD.
