* This motherboard supports RS232/422/485 on COM1, 2 ports.
Please refer to below table for the pin denition. In addition, COM1,
2 ports (RS232/422/485) can be adjusted in BIOS setup utility >
Advanced Screen > Super IO Conguration. You may refer to our
user manual for details.
COM1, 2 Ports Pin Denition
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.
