That would kill the Live CD problem, wouldn't it? Never really used one, so I don't know. Just asking / wondering.

No.

if you take the top off your pc on the motherboard there is a small silver round battery which looks a little like the type of battery's you see in watches the battery on the motherboard is called the cmos battery.

Anyway WITH THE POWER OFF THE WHOLE TIME pull the battery from whats holding it in place and leave the battery out for a minute or two then put the battery back in.

Then go into the BIOS then all the settings with be reset to their defaults even if you set a password the password will now be gone.

To try to prevent this problem you could look into "PC Entrapment Products" here are some links to some products available to give you some ideas:

EDIT: Sorry if i jumped in head first at the start of this thread but personal problems are getting the better of me right now and i just did'nt think about the physical side of security i was just thinking about answering his question.
