Installation of ROM Socket
- Do not apply force to the actuator cover after ic inserted.
- Do not apply force to the 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 the 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 the ASRI website.
Warning:
If the installation does not follow the picture, then it may cause severe
damage to the chipset & MB.
