If you attempt to install the card yourself but experience difficul- ties, it is recommended that you have an Apple-authorized service provider complete the process. Apple does not warranty damage caused by improper removal or installation of CPU cards.

•Prepare your work area by ensuring that you have a well

lighted space, preferably not on carpet (less static), and
