■Store the motherboard in an electrostatic shielding container or on an antistatic pad
whenever the motherboard is not installed.
■Before turning on the computer, ensure that there are no loose screws or metal
components on the motherboard or anywhere within the computer case.
■Do not use the computer in a high-temperature environment.
■Do not boot the computer before installation is completed. This could cause
permanent damage to the components as well as injury to the user.
