Power Supply Solution
The development board has the option to be powered from three different power
sources; an ATX power supply, an AC/DC switching power supply ('Mobile Brick'), or
up to 2 external batteries. The board contains all of the voltage regulators necessary
to power the system up. There are two main supported power supply configurations,
Desktop and Mobile. The Desktop solution consists of only using the ATX power
supply. The Mobile solution consists of using the Mobile iAMPS AC Brick in conjunction
with the batteries. When the Mobile solution is being used either AC brick or batteries
can be plugged in. When both AC brick and the batteries are connected at the same
time, the batteries are monitored and charged if necessary.
Note: Desktop peripherals, including add-in cards, will not work in mobile power mode. If
desktop peripherals are used, the platform must be powered using desktop power
mode.
Note: Please use an "ATX12V" 1.1 Spec compliant power supply regardless of Vendor or
wattage level (an "ATX12V" rating means V5 min current =0.1 A, "ATX" V5 min
current = 1.0 A, among other differences). For example, the Sparkle Model No.
FSP300-60BTVS meets this requirement and is an ATX12V 1.1 Spec compliant power
supply.
Note: This development board uses the Intel AMPS solution for AC brick. For more details
refer to Intel® Adaptive Mobile Power System (Intel® AMPS) White Paper (Doc
#603714) available from your Intel Representative
Note: If power button on the ATX power supply is used to shut down the system, please wait
at least 5 seconds before turning the system on again. We do not recommend
shutting down the system this way.

Manual VID support for Graphics VR
The development board supports manual VID operation for graphics Voltage
Regulator. Jumper J2H2 is provided to incorporate "VID override" to allow the
overriding of GMCH VID outputs to the graphics VR. The intent of this "VID override'
circuit is for ease of debug and testing. VID settings are contained in the IMVP6+
Specification (RS – Intel® IMVP-6 Mobile Processor and Mobile Chipset Voltage
Regulation Specification). Contact your Intel representative for access to this
document.
