After another long hiatus, I've come back to this project. After procrastinating for a couple of years we now have the flash dump of the EC, which we are now reverse-engineering.
We have so far dumped the BIOS from the FWH memory on board, reverse engineered it enough to find out it uses the EC (a Renesas M306K9FCLRP 16-bit micro) in order to check the password and password reset response. As a long-term goal we're thinking of porting Coreboot to them. The aim is to uderstand the laptop boot process better, with an immediate goal of writing a keygen for its' challenge/response mechanism, allowing us to actually boot them and use them as a lightweight Internet access platform. Since they are enterprisey laptops, we cannot just reset their password by unplugging the CMOS battery. We have acquired a bunch of BIOS locked Toshiba Portege R100 laptops. What you need to do, is remove the jumper and. When you find the jumper, look carefully. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
If you don't have the manual then look for the jumpers near the CMOS battery.

The computer's response should be: PC Serial No.= XXXXXXXXX Challenge Code= XXXXX XXXXX XXXXX XXXXX XXXXX.

Once you have created the key disk put it into the notebook's drive and turn it on, then push the reset button and when asked for password, press Enter. To create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it (if it's not formatted yet), then use a hex editor such as Hex Workshop to change the first five bytes of the second sector (the one after the boot sector) and set them to 4B 45 59 00 00 (note that the first three bytes are the ASCII for 'KEY':) followed by two zeroes). Some Toshiba notebooks allow to bypass BIOS by inserting a 'key-disk' in the floppy disk drive while booting. In other words, in general, BIOS passwords are not designed to be removed by the end user without some or significant assitance from Toshiba themselves. Most Toshibas have a way to reset the BIOS password, ranging from shorting two connections on the motherboard to getting Toshiba to send a special unlock code, to needing a special cable that only Toshiba and their authorised tech's have access to. I've got a Toshiba Satellite M300 that has a bios password set, but the password has been forgotten. It's a useful tool for users to get their lost BIOS password back, or clean passwords from an old computer bought from others. No need to pay expensive fees to experts. It's an bootable CD that runs on x86 and x86_64 computers. PC CMOS Cleaner is an easy-to-use tool to recover, delete, decode and display the superior passwords stored in BIOS whatever the brand is.
