* The thermal solution of whole system needs to
be designed additionally.
* This motherboard supports RS232/422/485 on COM1, 3, 4 ports. Please refer to
the table below for the pin denition. In addition, COM1, 3, 4 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.

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.
* +12V PWR in --- system loading under 65W
+19V PWR in --- system loading under 95W
PWR in ≥+24V for system loading over 95W
