BIOS admin password lost

I have a friend who's laptop was stolen, and before they got it back the password on their BIOS was set to something unkn own. Now they cannot access their laptop. If the password for the BIOS is set, is there a way to bypass it? Can the drive be mounted as a slave on another machine and read then or will it still be password protected? Is it possible to format the drive completely including the BIOS in order to reset the password?
Many thanks,
Bartley

BIOS Password Troubles?

Basically there are usually TWO types of BIOS password

1. Startup Password; This stops the PC booting till a password is entered.
2. BIOS password; This stops you entering the BIOS setup until a password is entered.

This information is held in a CMOS (Complimentary Metal Oxide Semiconductor) chip, this is used because it only requires a TINY amount of voltage to keep its settings. This voltage is usually supplied by a Lithium battery on the motherboard (Some Laptops don’t have this they store the info in Flash memory - Consult the handbook)

The easiest way CLEAR the settings is

1. Look in the motherboard Manufacturers handbook most have a set of "Jumper pins" which can be shorted using a "jumper" - This is a small plastic peg that shorts he pins. More modern motherboard actually have a reset switch.

2. Remove the battery, on VERY old PC's the battery is soldered on, if this is the case you need to either wield a soldering iron (which I don't recommend) or take it into the shop. ENSURE the PC is unplugged (at both ends) and remove the battery - leave the PC for at least 20 minutes, and replace the battery.

If you don’t fancy getting the screwdrivers out you DO have other options.

1. Flash the BIOS this resets everything, to do this you MUST have access to the floppy drive, visit the motherboard manufacturers website and find an "Updated" BIOS for your PC, Follow the installation directions TO THE LETTER.

2. Overload the Keyboard buffer; Overloading the keyboard buffer can crash the password routine and let the computer boot. Try this by pressing the ESC key repeatedly, possibly more than 100 times. (I’ve not tried this - I’m to impatient :0)

3. Try a dedicated BIOS cracker

RemPass http://natan.zejn.si/rempass.html

4. Try various known "Back Door" Passwords these differ depending on the BIOS manufacturer (usually written on the chip)
