Installation of ROM Socket
- Do not apply force to the actuator cover after IC inserted.
- Do not apply force to actuator cover when it is opening over 120 degrees. Otherwise, the actuator cover may be broken.
- The yellow dot (Pin1) on the ROM must be installed at Pin1 position of the socket (white arrow area).
- Make sure the white dot on the ROM is installed outwards of the socket.
- For further details of how to install ROM, please refer to ASRI website.
Warning: If the installation does not follow as the picture, then it may cause severe damage to chipset & MB.
