How can I display the system password

Please tell me,how can I display the system password stored in CMOS Battery by using C -language code.
Also how can I change it using C.

I doubt its possible, for security... what good is a password changeable by any old program?

if it is possible, it's probably mainboard-specific

I know how to get around a bios password, but should i tell him?
What did you forget your password? or is this to get into someone elses computer.

www.google.com ?? :)
