Installation Of Rom Socket

  * Do not apply force to the actuator cover after ice inserted.
  * Do not apply force to actuator cover when it is opening over 120 degree, 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.
