• Trusted Platform Module (TPM) Support By combining the onboard TPM 1.2 with TPM security software (provided by the third party), it will enhance the security level of the system. • PRECAUTION: When TPM is enabled and utilized through TPM software, there is possibility that the encrypted data will not be accessible, or recoverable if one of the following situations occurred: 1.
Before you proceed Take note of the following precautions before you install mainboard components or change any mainboard settings. • Unplug the power cord from the wall socket before touching any component inside the system. • Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity.
Mainboard Overview Before you install the mainboard, study the configuration of your chassis to ensure that the mainboard fits into it. Make sure to unplug the power cord before installing or removing the mainboard. Failure to do so can cause you physical injury and damage mainboard components. 1.5.1 Mounting Holes Place the screws into the mounting holes indicated by red squares to secure the mainboard to the chassis.

System Memory 1.6.1 Overview The mainboard comes with two 204-pin Double Data Rate 3 Low voltage (DDR3L) Dual Inline Memory Modules (SODIMM) sockets. A DDR3L module has the same physical dimensions as a DDR SODIMM but has a 204-pin footprint compared to the 240-pin DDR2 DIMM.
You may ONLY install 1GB, 2GB, or 4GB DDR3L-1333MHz (PC3-10600); Non-ECC, Un-buffered 1.35V DDR3L memory modules on this board (4GB maximum for each slot). MX1900J does not support DDR/ DDR2/ DDR3 SODIMM modules, DO NOT install DDR/ DDR2/ DDR3 SODIMM modules on this board.
1.6.3 Installing the DDR3L SODIMM Make sure to unplug the power supply before adding or removing SODIMMs or other peripherals from the system. Failure to do so may cause severe damage to both the mainboard and the peripherals. 1. Locate the SODIMM socket onboard. 2.
1.6.4 Removing the DDR3L SODIMM Follow these steps to remove a SODIMM. 1. Press the two ejector tables on the slot outward simultaneously 2. Remove the SODIMM module from the socket. Hold the SODIMM module gently when pressing the ejector tabs. The SODIMM might get damaged when it flips out with extra force.
Find the proper orientation and push down firmly until the connector is completely fit. In order to power on MX1900J through this connector, the signal “PSON” must be connected with the “GND” signal on the 20/24 pin ATX power connector.

1.9.6 Front USB2.0 Headers: USB56, USB78 Be sure the pins of VCC and GND signals are connected to the USB2.0 headers correctly. Otherwise, it may cause damage to the USB port and/or the connected USB device. 1.9.7 Serial Port Connector: COM1...
1.9.12 Digital I/O Connector: JDIO1 This header provides 8-bit general purpose I/O (GPIO) connections to external device. Customer can write their own monitoring program to monitor the status of external device connected with this header. 1.9.13 The Header: JPSONLOCK1 This header is reserved for factory internal use only.
1.10 Jumpers 1.10.1 ATX/AT Mode Selection: JPSON1 This header provides the option to boot the system in the form of ATX mode (default) or AT mode. When the system is set in AT mode, the system power on/off will be controlled directly by the power switchon power supply.
For normal state (default), the jumper is set on pin location 1 and 2. To clear the CMOS, disconnect all power connections to MX1900J first, then set the CLCMOS1 jumper to pin location 2 and 3 for at least 30 seconds while the system is off.
