Burning Bootloadter to Atmega168P

I have an Atmega168P chip instead of the normal Atmega168. When I try to burn the bootloader I get...

avrdude: Expected signature for ATMEGA168 is 1E 94 06 * Double check chip, or use -F to override this check.*

How can I override this error to burn the bootloader please?

Any ideas anyone?

No not really. That refers to burning them using AVR-Studio. I would like to be able to use the Arduino IDE.
