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.It will now let you install Windows XP or any other Operating System.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.
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.
You'll need to fold the keyboard in such a way that you don't damage the cable. Anyone having an idea on how I can reset the password on my computer ?
If you don't get the password screen, then the password is a hard drive password and not a P-O-P.
Toshiba says that the BIOS version should be at least v1.30. Select your laptop model and find any downloads for the BIOS.
In the BIOS change history you will see the description of changes.
