INSTALLATIONS Installing the CPU The MB950 board supports an LGA1156 Socket (shown below) for Intel Clarkdale processors. . To install the CPU, unlock first the socket by pressing the lever sideways, then lift it up to a 90-degree. Then, position the CPU above the socket such that the CPU corner aligns with the gold triangle matching the socket corner with a small triangle. Carefully insert the CPU into the socket and push down the lever to secure the CPU. Then, install the heat sink and fan.
INSTALLATIONS Installing the Memory The MB950 board supports four DDR3 memory socket for a maximum total memory of 16GB in DDR3 DIMM memory type. Installing and Removing Memory Modules To install the DDR3 modules, locate the memory slot on the board and perform the following steps: 1. Hold the DDR3 module so that the key of the DDR3 module aligned with that on the memory slot. 2.

APPENDIX Appendix A. I/O Port Address Map Each peripheral device in the system is assigned a set of I/O port addresses which also becomes the identity of the device. The following table lists the I/O port addresses used.
APPENDIX B. Interrupt Request Lines (IRQ) Peripheral devices use interrupt request lines to notify CPU for the service required. The following table shows the IRQ used by the devices on board.
APPENDIX C. Watchdog Timer Configuration The WDT is used to generate a variety of output signals after a user programmable count. The WDT is suitable for use in the prevention of system lock-up, such as when software becomes trapped in a deadlock. Under these sorts of circumstances, the timer will count to zero and the selected outputs will be driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts to zero.
