If you have enough physical access to boot the machine from a CD, you have enough access to work around the BIOS password problem. In almost all cases, cracking the case and changing/removing a jumper on the motherboard will bypass/reset the password, and Google will tell you which jumper it is.

This is true; with the exception of some incredibly poorly designed HP desktops I once had the misfortune of administrating. For some insane reason HP decided to store the BIOS password in flash RAM and declined to provide any method for resetting it. In the manual, they specified "If you for any reason forget your BIOS password, please ship the computer to a certified service station to have it reset". The only other known way is to unsolder the surface-mount flash chip from the MB and place it in a flash writer.

We've since managed to lose the passwords for a few of those desktops; is there any way to get linux to overwrite the flash RAM soldered to the motherboard?
