COM3 Port Pin Denition
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
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.
