about bios setting...
 

I have an ibm thinkpad r52 laptop and i have accidentally enabled the "lock BIOS settings" setting. though i can still get into bios i cannot change any of the values. i cannot even access bios via the supervisor password that i just set. is there a workaround that i could do besides removing the cmos battery? your help is very much appreciated. btw, the laptop still starts up and i can use it as i always have. thanks in advance. ---ibnyuseff
